datagrid return value - please help

smd5049 — Fri, 06 Nov 2009 16:37:35 GMT

will someone please help me with this. It seems simple enough but I'm very new to asp and vb. I have a datagrid and I want to know how to access the values in a specific column. The dg is bound to a sql query. The column returns integer values in sql. I want to be able to sum the column and have a button_click command send the datagrid values to 0. I only want to change the datagrid values NOT the sql values (I currently have an Update/Set sql command in vb for this but as I said I only want the Datagrid values to change). Simply put where, if anywhere are the datagrid values stored? I have the column set as a template column and the items are displayed in the datagrid as textboxes (to allow the cells in this column to be changed). can someone please help or at least tell me if this question makes any sense. thank you

Membership, Profiles and Security

Sazabi02 — Fri, 06 Nov 2009 00:47:07 GMT

I've been reading a bunch of books on how Membership and Profiles can make an ASP.NET developer's life easier but these kind of things are usually too good to be true. Any idea on the drawbacks and security issues I'll have to compromise if I choose to implement either? I've been browsing the internet and I haven't found a reasonable answer yet.

Ohhh.. Posted on the wrong forums. Sorry...

help with datagrid

smd5049 — Thu, 05 Nov 2009 20:47:45 GMT

I have a datagrid bound to a sql proc. I have made the last column in the datagrid into text boxes so the items are editable. how do i return the values from these cells? Basically I want to be able to sum the entire column, as well as set the values in each item of the column to 0 upon a button_click. I'm very new to vb.net and if I'm not explaining this correctly please let me know.

the datagrid is built through this funtion:

             Dim strConnString As String

            Dim strSQLText As String

            strConnString = ConfigurationManager.ConnectionStrings("SDWConnectionString").ToString

            strSQLText = "SELECT TN_CN_S_Desc, Item, Pack, Location, Lot, Label_Nb from sdw.sdw_user.SAR_DTD_840_copy where Pick_Num = '" & Picklist & "'"



            Dim SqlCOnnection As New SqlConnection(strConnString)

            SqlCOnnection.Open()



            Dim sqlCmd As New SqlCommand(strSQLText, SqlCOnnection)



                     Dim adapter As New SqlClient.SqlDataAdapter(strSQLText, SqlCOnnection)



            Dim ds As New DataSet

         

            adapter.Fill(ds, "sdw.sdw_user.SAR_DTD_840_copy")

            Dim dataTable = ds.Tables("sdw.sdw_user.SAR_DTD_840_copy")



            Me.DataGrid1.DataSource = dataTable

            Me.DataGrid1.AutoGenerateColumns = False

            Me.DataGrid1.DataBind()

the html for the column that I made editable and want to sum/set to zero looks like this:



                                        

                                            
                                                    Width="65">

Application Homepage with Favorites

Stretcher75 — Wed, 04 Nov 2009 12:45:19 GMT

I'm developing a program that will have a tree control that will aloow the user to navigate around the application. There will be over 50 nodes on the tree from adding, editing & Listing Customers, Items, Invoices, Credit Memos etc. I have a main page that when the user logs in they arrive at their homepage of the application. Let's say be on the Customer Listing page and they use this page daily, instead of clicking through the tree control looking for the node I would like the user to be able to add the Customer Listing page to their homepage as an icon or a text description saying "Customer Listing". This will allow for the user to be able to save all their most accessed pages to their homepage for easy access everytime they login or navigate back to the homepage. Does anyone have an example they can share or any information? I am using VB code.

Thanks

UserControl postback problem

Falzz — Wed, 04 Nov 2009 11:58:41 GMT

Hi All!

Im having a problem regarding PostBack issues. Ive got a user control (WebUserControl1.ascx) which dynamically creates labels according to the value it is set from the Default.aspx page.

Code In Default.aspx.cs

public partial class _Default : System.Web.UI.Page

    {

        WebUserControl1 _control = new WebUserControl1();



        protected void Page_Init(object sender, EventArgs e)

        {

            _control = Page.LoadControl("WebUserControl1.ascx") as WebUserControl1;

            _control.clickedEvent += new EventHandler(_control_clickedEvent);

        }



        protected void Button1_Click(object sender, EventArgs e)

        {

            _control.Count = 5;

            _control.clickedEvent += new EventHandler(_control_clickedEvent);

            _control.draw();

            

            PlaceHolder1.Controls.Add(_control);

        }



        protected void _control_clickedEvent(object sender, EventArgs e)

        {

            Response.Write("Test");

        }

Code In WebUserControl1.ascx.cs

public partial class WebUserControl1 : System.Web.UI.UserControl

    {

        public event EventHandler clickedEvent;



        private int _count;



        public int Count

        {

            get { return _count; }

            set { _count = value; }

        }



        public void draw()

        {

            for (int i = 0; i <= _count; i++)

            {

                Button button = new Button();

                button.Text = Convert.ToString(i);

                button.Click += new EventHandler(button_Click);

                Panel1.Controls.Add(button);

            }

        }



        void button_Click(object sender, EventArgs e)

        {

            clickedEvent(this, e);

        }

    }

Now, on Default.aspx I have a button which creates the instance of a control and assigns the value to count which is then placed on the PlaceHolder. However when I click on the buttons (the ones dynamically created) the click event isnt firing, and the WebUserControl in Page_Init is set as null, meaning its losing its reference

Can anyone help out please?

Thanks

Help with insert statement

twilitegxa — Wed, 04 Nov 2009 09:09:23 GMT

Can anyone help me with why my insert statement won't work? I have tried countless tutorials online, but I cannot figure out what I am doing wrong. Can anyone point me int the right direction here? Here is my form:

form:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="form.aspx.cs" Inherits="_form" %>

<%@ Import Namespace="System.Data.SqlClient" %>













    Add Character





    

    

    Add


    Identity:

    


    Name:

    



    
            onclick="add_char_Click" />

form (code-behind):

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Data.SqlClient;

using System.Configuration;



public partial class _form : System.Web.UI.Page

{

    protected void Page_Load(object sender, EventArgs e)

    {

    }

 protected void add_char_Click(object sender, EventArgs e)

    {

     SqlConnection conn;

     SqlCommand comm;

     string connectionString = ConfigurationManager.ConnectionStrings["smrpg"].ConnectionString;

     conn = new SqlConnection(connectionString);

     comm = new SqlCommand("INSERT INTO scouts (charID, char_identity, name) VALUES (@charID, @char_identity, @name)", conn);

     comm.Parameters.Add("@charID", System.Data.SqlDbType.Int);

     comm.Parameters["@charID"].Value = 10;

     comm.Parameters.Add("@char_identity", System.Data.SqlDbType.NVarChar, 50);

     comm.Parameters["@char_identity"].Value = char_identity.Text;

     comm.Parameters.Add("@name", System.Data.SqlDbType.NVarChar, 50);

     comm.Parameters["@name"].Value = name.Text;

     try

     {

         conn.Open();

         comm.ExecuteNonQuery();

         Response.Redirect("repeater.aspx");

     }

     catch

     {

         dbErrorMessage.Text = "Error submitting the character! Please try again later, and/or change the entered data!";

     }

     finally

     {

         conn.Close();

     }

 }

    }

I have three fields:

charID, int, allow null unchecked, primary key, is identity yes
char_identity, nvarchar(50), allow null unchecked
name, nvarchar(50), allow null unchecked

What have I done wrong? I am connecting to the database and can display the records in the table, I just can't insert new records from a form for some reason. What am I doing wrong? It only displays my error message when I try to submit the form.

Trying to compute total based on gridview items

dfs3000my — Tue, 03 Nov 2009 13:09:58 GMT

Hi,

I'm actually trying to compute the total for my individual gridview items but I am reaching the dead end at the moment.

I had an idea that probably I can specify another datasource for my total computation but was told that gridviews may only be bound to one datasource at a time.

My second idea simply tells me that, do I have to compute the total in the SQL statements itself as my SQL is already pretty complicated. Attached is how the gridview looks like and what I am trying to accomplish.

I hope someone could actually guide me through this process. Thanks in advance

Below is my ASP code:



            

                

                    

                        <%# Container.DataItemIndex + 1 %>

                        Max((CASE WHEN RowNumber = 3 THEN total ELSE '' END)) AS hurdle3, 

                        Max((CASE WHEN RowNumber = 4 THEN total ELSE '' END)) AS hurdle4,

Crystal Report Best Practice Question

mkosucu — Tue, 03 Nov 2009 10:37:26 GMT

Hello All;

I have got a task regarding parameter passing to Crystal Report via Crystal Report, I would like to find best way to achieve it.

Imagine that I have got parameterized and non reports-parameterized. I am developing a report manager that will enable users to subscribe to the reports and schedule them with their parameters. I have got a subscription web page with the list of reports. When a user wants to subscribe to a report and schedule it, if there is no parameter in the report, it is fine but if there is any parameter that needs to be passed to the report(which we can find from rpt file), user should be able to enter these parameters values via a panel in the page. and I will save those parameters' values to the database.

Effectively, I need to create a parameter entry panel to get the parameters and save them to the database with their type, value and so on, then I need to use these parameters programmatically for exporting reports to the different file formats.

Basically, I must develop parameter entry panel run time in accordance with the parameter types that the corresponding report has.

Does anyone have any idea what the best way is to achieve it?

Thanks for your help from now on and please ask for further clarification if needed/

Kind Regards.

Custom Validation Check Duplicate Data

Stretcher75 — Mon, 02 Nov 2009 18:37:42 GMT

I'm still trying to get my validation to work correctly. So far if a user enters in a Salesman Code that exists in the database it displays the error message when tabbing off the field. The Salesman Code field is also required so I can't get this validator to work either with the customer validator that checks duplicates. What I am looking for is when a user does not enter a Salesman Code for the error to appear and not let the user submit the form. If the user enters a Salesman Code that exists in the database the error message will be displayed and the user should not be allowed to submit the form. Any help or examples would be appreciated. Below is my code that I have using VB.

Below is my aspx page:

Can't Recompile My Website
quickershopper — Sat, 31 Oct 2009 06:43:00 GMT
I'm a first time hoster, so I apologize for the novice question. When I'm working on my local computer, everything is fine, but I'm just having a problem on the hosting server.  



I use FileZilla to edit my website. When I edit the main page (.aspx), the system automatically recompiles the changes and everything works fine. However, when I make changes to the CodeBehind page (.aspx.vb), the website doesn't recongize the changes...



I've tried making the changes on my local computer, Build Solution, and everything works.  I then delete the web page off the server and upload the new page... but still no changes...  I've tried deleting all the files off the sever and uploading everything again, but then I run into a problem where the website is looking for files off the localhost, instead of the server... I had to pay someone $150 originally because I couldn't figure out why the website kept looking for localhost instead of the server.   I'm hoping I can learn the cause of this instead of hiring someone again.  



I just need to know the easiest way to recompile the changes I make to the codebehind page.  Do i need to recompile/reupload the whole site? just the one page that I made changes to?  is it something in the global.asax/assembly/web.config that i need to recompile???



Thank you so much to all who answers!!!

Problems with dynamic Excel with Module
Jojo1974 — Fri, 30 Oct 2009 21:08:37 GMT
Hi, I am hoping someone can help with a problem I am having



I am using ASP (VB).Net 2003 on Windows Server 2003 and I am trying to create a web application which dynamically creates an excel spreadsheet which has a module included. When I run this on the local host it works fine but once I load it onto the server I get the following error message



HRESULT = 0x800A17B4 "Programmatic Access to Visual Basic Project is not trusted



I am using the following VB.Net code 

Code:

 Dim xlmodule As Object 'VBComponent

xlmodule = xlbook.VBProject.VBComponents.Import(PathToImport & "Module1.bas")
If I turn off the code then it will load the spreadsheet without the module but the module is the critical part of the spreadsheet. 



I have tried changing permissions but this is running on a client and not a physical machine. I am populating on the server in Excel 97 to avoid microsofts security issues



Does anyone have any ideas?



Regards

programmaticly alter the command text of a sqldatasource???anyone?
ricksvoid — Fri, 30 Oct 2009 18:40:18 GMT
I have a simple sqlDataSource  that populates a GridView control

Nothing out of the ordinary here.

                         
                            SelectCommand="SELECT customerID, lname, fname, dateNow FROM dbo.customers ORDER BY lname ASC">

                        



                   
                                   AutoGenerateColumns="False" DataKeyNames="customerID" AllowSorting="True">

                            

                            

                            

                            

                                

                                

                                

                                

                             

                                
                                    SelectText="Select" ItemStyle-HorizontalAlign="left"

                                    HeaderText="Details" >

                                

                                

                            

                        


The problem is that my client wants to be able to click a button and refine the querry by only showing certain records instead of all of them.  Can i do this programmaticaly? Can I programaidically change the  commandtext so that it says :

SELECT customerID, lname, fname, dateNow FROM dbo.customers WHERE rep is null> ORDER BY lname ASC



I beleive that i can but im unsure of what the proper syntax is.  Remember, I want the gridview to display all records by defalut and only filter them as the result of some event such as a button click.



Thanks in advance.

radiobuttonlist postback error
phantom1000000 — Fri, 30 Oct 2009 12:20:36 GMT
Hi all,

I've got a spot of bother with my radiobuttonlist.  It has 3 items in it and I want them to control the visibility of certain divs/tables.



But even simple text changes are becoming a headache and the postback is not firing the event I clicked on but the PREVIOUS event (ie, I click on value 1 and text shows nothing, I click on value 2 and text shows value 1, I click on value 3 and text shows value 2)...always 1 step behind.



Here's my code:

 function SetMessageInTextbox() {

var rdolist_0 = document.getElementById("rdolist_0");

var rdolist_1 = document.getElementById("rdolist_1");

var rdolist_2 = document.getElementById("rdolist_2");

if (rdolist_0.checked)

document.getElementById("TextBox1").value="One";

if (rdolist_1.checked)

document.getElementById("TextBox1").value="Two";        

if (rdolist_2.checked)        

document.getElementById("TextBox1").value="Three";

}


I've tried combinations of adding attributes in the vb.net pageload function, the vb.net code behind rdoList.selectindexchange using

rdolist.Attributes.Add("onload", "javascript:SetMessageInTextbox()")

and also the onClick event of the HTML page.



If you can assist, please do. 


/forums/clientscript.RegisterClientScriptBlock doesnot work in UpdatePanel
mania_comp — Fri, 30 Oct 2009 09:27:32 GMT
Hi friends..



I am trying to display message box using server-side code. I have written code in buttons click event and Page Load Event. It is as follows :



     Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        TextBox1.Text = "I Enjoy ASP.NET"



        Dim myscript As String = "alert(document.getElementById('TextBox1').value);"

        Page.ClientScript.RegisterStartupScript(Me.GetType(), "myscript", myscript, True)

    End Sub



    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim strMessage As String

        strMessage = "Hi, You clicked ClickMe button"

        Dim strScript As String = ""



        If (Not ClientScript.IsStartupScriptRegistered("clientScript")) Then

            ClientScript.RegisterClientScriptBlock(Me.GetType(), "clientScript", strScript)

        End If

    End Sub


If button is not in UPDATE PANEL, then both alert are displayed normally (i.e. during Page Load and Button Click)



But when I put the button inside UPDATE PANEL , alert dosn't work in Button Click. Here only Page_Load alert is displayed 

In case of UPDATE PANEL is also tried

 Me.UpdatePane1.GetType() 

but in vain..!!!

Any ideas??

BoundFields with different DataSources
dfs3000my — Thu, 29 Oct 2009 05:31:30 GMT
I'm currently populating my GridView using code-behind codes and it looks like this:-



 BoundField boundField = new BoundField();

boundField.DataField = "student_name";

boundField.HeaderText = "Name";

GridView1.Columns.Add(boundField);


Is there a possibility where I can have a different DataSource for the different BoundFields that I insert?



Perhaps, Column 1 - 5 uses SQLDataSource1, Column 6 uses SQLDataSource2, and Column 7 uses SQLDataSource3 


Update INT type Checkbox Field
Stretcher75 — Wed, 28 Oct 2009 17:41:20 GMT
I'm having an issue trying to update a field in my database that is a INT type. I'm using this field for a  checkbox on my form. The checkbox works correctly by using the field in the database containing a 0 for unchecked and a 1 for checked. The problem is when I try to update my form the checkbox field errors out. The error says:



Conversion failed when converting the varchar value 'on' to data type int.





Below is my code which works fine asides from this problem:





 Sub Page_Load()

strSQL = "SELECT * FROM tblCustomers WHERE Customer_ID=" & Request.QueryString("Customer_ID")

    

        DataBase_Connect(strSQL)

        objDataReader.Read()

The code below is a sample of my form code:

  Inactive:

 Customer Code:

Any help would be appreciated. I would like to use the code I have just with correcting the checkbox field updating problem.

I am using .Net 2 in Vs 2008 and I am trying to get the onclick event for  a checkox to fire when clicked. Unfortunately it is not firing. I can see the code is added to the checkboxs html.



This is the checkboxlist:

 


this is the code that set the onclick attribute:

  protected void chkSides_OnItemDataBound(object sender, EventArgs e)

    {

        

        CheckBoxList chkSides = (CheckBoxList)sender;

        foreach (ListItem listitem in chkSides.Items)

        {

            listitem.Attributes.Add("onclick", "alert('hey');");

        }

    }


The checkboxlist is databound and within a databound repeater.



Any ideas?

What should i charge for developing the followin project
ricksvoid — Sat, 24 Oct 2009 22:53:04 GMT
Im a recent grad working on my first paid project as an aspiring freelance .net developer. I have no idea what to charge for the project description below:



Client needs a web app to manage sales leads. Sales reps, managers, and call center will all be able to insert a sales lead (name, address, phone number ect ect) into sql database table.

Only the manager will be able to access these records via a GridView of last names arranged alphabeticaly. Once the manager clicks on a name, the details are then presented in a

FormView control. Manager can then assign a rep to each perticular lead.

When a rep logs in he will only see his leads arranged in the same way "Master/details". He will also be able to update comments unto the nature and state of the lead eg..sold,killed,next month.

Manager will also have the abillity to delete and create new reps and assign them passwords..



Ive got it all figured out, I just need to know what i could/should charge for this project. Please no hour/rate equations. This wont work for me as i am a recent grad and this will take me twice as long to develop as would a seasoned professional. I am interested in knowing what the final damage should be. I apreciate any feedback.

What is the difference between PostBack and IsCallback ( !IsPostBack and if(!IsCallback)) 



Like in the following Code Snippet:



 



      public partial class _Default : System.Web.UI.Page

    {

        protected void Page_Load(object sender, EventArgs e)

        {

            if (!IsPostBack)

            {



            }



            if(!IsCallback)

            {



            }

        }

    }
 



As far as I know, when I 1) refresh the page or 2) revert back to the page after round trip, the behavior is such that IsPostBack = !IsCallback. I don't find any difference.



Can you please explain with example code?



 I just want a sample code (for Page_Load event) that will demonstrate the difference in the Page_Load event so that I can toggle breakpoint and understand it for myself.



Thanks.
