I am creating a update member page. I would like the page to auto retrieve the information he or she originally used while registering on my site and display them into the individual textboxes of the update profile page, this is to prevent the hassle to rekey in every individual details and allow the user to edit what he or she wants before it is updated into the database.

I am having problem retrieving information from the database and displaying them into the individual asp.net web text boxes. I am trying to use SQL DataAdapter or SQL Reader, but both fails. Some help to resolve this problem please, an example with code snippets will be very much appreciated. :rolleyes:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

 displayrecord()
        End If

 Private Sub displayrecord()
 SqlConnection1.Open()
        Dim SqlDataAdapter1 As New SqlDataAdapter("SELECT * FROM Member", SqlConnection1)
        Dim objReader As SqlDataReader
        Dim SqlCommand1 As New SqlCommand("SELECT * FROM Member", SqlConnection1)
        SqlDataAdapter1.Fill(dsMember)
        objReader = SqlCommand1.ExecuteReader()

        objReader.Read()
        txtbox_user.Text = objReader("MemberUserName")
        txtbox_password.Text = objReader("MemberPassword")
        txtbox_confirmpass.Text = objReader("MemberPassword")
        txtbox_name.Text = objReader("MemberName")
        txtbox_birthdate.Text = objReader("MemberDOB")
        txtbox_nric.Text = objReader("NRIC")
        txtbox_address.Text = objReader("MemberAddress")
        txtbox_contact.Text = objReader("MemberPhone")
        txtbox_email.Text = objReader("MemberEmail")
        Dropdown_Gender.SelectedValue = objReader("Gender")
        DropDown_Age.SelectedValue = objReader("Age")
        DropDown_Income.SelectedValue = objReader("Income")
        DropDown_Children.SelectedValue = objReader("NumofChildren")
        DropDown_HearUs.SelectedValue = objReader("HowDidYouKnowAboutUs")
        objReader.Close()
        SqlConnection1.Close()
    End Sub

you can use data reader for this,

command = new SqlCommand("SELECT * FROM Member",sqlConnection );
command.CommandType = CommandType.StoredProcedure;
try
{
     sqlConnection.Open();
     reader=command.ExecuteReader();
     while (reader.Read())
{
//if it is a text box 
txtbox_user.Text=reader.IsDBNull(reader.GetOrdinal("MemberUserName"))? null: reader["MemberUserName"].ToString();
//if it is a dropdown put defalut value 0 or 1, what ever value you use.
DropDown_Children.SelectedValue=Convert.ToString(reader.IsDBNull(reader.GetOrdinal("NumofChildren")) ? (int)0 : (int)reader["NumofChildren"]);						
					
}
}
catch(Exception ex)
{
   throw new Exception(ex.Message);
}
finally
{
   reader.Close();
   sqlConnection.Close();
}

Hi Aish,

I do not understand what is this line of code is doing except a rough guess that it is trying to read the column MemberUserName. Would you mind explaining it to me? In addition, i am writing this code using ASP.NET with VB. Would you mind tuning this part of the codes that i have quoted into ASP.NET with VB as i am having a hard time trying to fix it into that. :o

//if it is a text box
txtbox_user.Text=reader.IsDBNull(reader.GetOrdinal("MemberUserName"))? null: reader["MemberUserName"].ToString();
//if it is a dropdown put defalut value 0 or 1, what ever value you use.
DropDown_Children.SelectedValue=Convert.ToString(reader.IsDBNull(reader.GetOrdinal("NumofChildren")) ? (int)0 : (int)reader["NumofChildren"]);

Naters,

I've seen an error already, look at the code.

Why do you have a closing "End If" on the Sub Page_Load were you don't have an opening If? That should be End Sub

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

displayrecord()
End If


Post the the SQL error message that way it is easy to troubleshoot.

Regarding this set of codes, can i know how to display the records using OleDbConnection, OleDbReader?

I have got the same problem, if anyone helps you they are helping me as well

frossie,

your post is 3 years ago.. I'll answer it anyway..

just add:

Imports system.Data.OleDB -- for VB
using System.Data.OleDB -- for C#

then revise the code by changing Sql to OleDB..
EX: SqlCommand to OleDBCommand.

Hope this one helps!
