Here is a picture of a form. http://postimage.org/image/a813nony5/

Please help:
I have a form with:
- 4 textboxes (textbox 11,21,311 & 41)
- 4 buttons (add, delete, save, refresh)
- 1 DataGridView (MS Access database connected)
- 1 filter to filter the data through DatagridView

Here is the story:
When I use buttons to navigate the database, I have to click ten times on button "Next" to go to the tenth record.
Code for that is:

(...)
BindingContext(DatasetTelefonija1, "Telefoni").Position = BindingContext(DatasetTelefonija1, "Telefoni").Position + 1
(...)

What if I have onehundred records?

So, I explored the internet and made another code: using DataGridView to click items and sending the data to text boxes.
Code for that is:
(...)
TextBox21.Text = DataGridView1.Item(1, DataGridView1.CurrentRow.Index).Value.ToString
(...)
Data is shown in textboxes, but problem is when I click on button Previous or Next, it gives me an error.
Problem is when you select data in datagrid, it is shown in textboxes but it is not shown in (i think) in "DatasetTelefonija", so when I use Delete button, it deletes the first record.

Also, I need to add that textboxes have properties -> data -> data bindings set.

Another Question.
When I use filter and start typing, results are not shown until I write an exact word.
Example: word in database is Animal. When I start typing letters "An" it doesnt show me a single word until I type a whole word "Animal".

Code for that is:
(..)
Me.TelefoniBindingSource.Filter = "[NameandSurname] = '" & TextBox5.Text & "'"
(...)
Also, problem with this "filter search" is when I delete everything, datagridview doesnt show a single record.
I used DataGridView.Refresh() method, but nothing.

Here is the whole code:

Found solution for filter data.
Still don't know the navigation problem.

I recommend that you create a BindingNavigator to manage navigation.
Your current implimentation has no error checking and the navigator will do all that for you.
http://msdn.microsoft.com/en-us/library/system.windows.forms.bindingnavigator(v=vs.90).aspx

With a navigator you can define the buttons that handle navigation. The one draw back is that they need to be ToolStrip items. Add an undocked toolstrip for each button that you want to have in your form and set the autosize property to false; also set the LayoutStyle to Table. To replace your current buttons, add a Toolstipbutton to the toolstrip and make it look like your original button. You can also add buttons for goto first and goto end. To allow jumping to a specific row (PositionItem), add a toolstriptextbox. To get a total of the row, add another toolstriptextbox for CountItem and make it read-only.

If you do this and modify your code as follows, you can delete all your existing button-click code and your "gridvalues" method code.

On an issue of readability, I suggest that you name the buttons and textboxes to reflect what they actually display on the form.

Private MyNavigator as New BindingNavigator(False)

Private Sub Telefon_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    OleDbDataAdapter1.Fill(DatasetTelefonija1)
    DataGridView1.Columns(0).HeaderText = "Redni broj"
    DataGridView1.Columns(1).HeaderText = "Ime i prezime"
    DataGridView1.Columns(2).HeaderText = "Telefon"
    DataGridView1.Columns(3).HeaderText = "Ostalo"


    With MyNavigator
       .Parent = Me
       .BindingSource = Me.TelefoniBindingSource
       .PositionItem = ToolStripTextBox1
       .CountItem = ToolStripTextBox2
       .MovePreviousItem = ToolStripButton1
       .MoveNextItem = ToolStripButton2
       .AddNewItem = ToolStripButton3
       .DeleteItem = ToolStripButton4
       .MoveFirstItem = ToolStripButton5
       .MoveLastItem = ToolStripButton6
    End With

    'You may want to make these textboxes read-only.
    TextBox1.DataBindings.Add("Text", _
                               Me.TelefoniBindingSource, _
                               "Redni broj", _
                               False, _

Edited 4 Years Ago by TnTinMN: added info

Thank you for response.
I'm sorry but I prefer a program without Binding Navigator. Don't ask why...

My new code is this and somehow is working... (I edited the names for you to understand it better)

Question: 1.How can make copy-paste method in datagrid and database?
Example: I click on DataGridView on selecteded Row, then I press copy -> then press paste -> new window/form/dialog box pop's out with data in it, if edit data is needed, then press button to save changes.

  1. I don't know if method I'm using to refresh datagrid view is Ok?
    Procedures related to this questions are: PhoneNumber_MouseHover and button6 and Refresh2()

  2. In this form I have a button to add new contact in phonebook. When pressed, new window pop's out to add new contact. I made this form, but I needed to put in again, BindingSource, Dataset and Adapter. Is this Ok?

I mean, it works, but I don't know if it will be "successful" on second computer.

Once again, thank you for response.
