Solution 1

I have never done that, but could you just add an EventHandler for the Textbox?

<asp:TextBox runat="server" OnTextChanged="Text_OnTextChanged" ID="Text"></asp:TextBox>

In the CodeBehind you can just use the sender to get the Text:

protected void TextBox1_TextChanged(object sender, EventArgs e)
{
  TextBox text = sender as TextBox;
  text.Text; //this is the text.
}

While this might look like actual Code, this is untested pseudocode for illustration only!

Added after your clarification:
Ok so you need this:

Sub GridView_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs){
	Dim index As Integer = Convert.ToInt32(e.CommandArgument)
	Dim row As GridViewRow = GridView.Rows(index)
	TextBox lName = row.FindControl("Lname") as TextBox;
	TextBox fName = row.FindControl("FName") as TextBox;
	Label empId = row.FindControl("EmpId") as Label;
}

Assuming all your Controls have the id set like this in the ASP Markup id="Lname". This needs to be exactly like the Parameter of FindControl.

Hope this helps, and again no checked code, may contain typos.

Thanks for reply
yes ur code works fine in case of get the value of same control but my problem is can i get the value of another textbox on this event. I mean

{
TextBox text = sender as TextBox;
text.Text; //here i can get only this controls value can i get another controls value from here.
}

Sure, which control do you want? Do you want to synchronize all the text boxes? You could iterate through all the rows and use the Cell.FindControl method for that. Tell me what you need and I try to help you.

i have a four columns datagrid like
EmpId FName Lname Save
(label) (textbox) (textbox) (Commandbutton)

These all are template fields

I hope now u will understand my problem

Morl99 13-Jun-11 5:16am

Where? i edited my Solution to Target your problem with the row controls. If that didn't help, please describe your problem further.

Sachin__Sharma 13-Jun-11 23:49pm

Friend i am using datagrid which has no RowCommand event you are using gridview i think. Its easy in the gridview but they are using datagrid where i work.

Morl99 14-Jun-11 2:36am

So how does your event listener for the command button look like? You can probably do e.Item.ItemIndex or something? Then my may will still work... Adapt it or show me your markup so I do not have to keep guessing your situation (which I will stop doing now)

Sachin__Sharma 14-Jun-11 5:17am

Protected Sub txt_Type_TextChanged(sender As Object, e As EventArgs)

Dim tb As TextBox = CType(GridAddType.FindControl("txt_Type"), TextBox)
Dim lb As Label = CType(GridAddType.FindControl("lbl_Td"), Label)
Dim chk As CheckBox = CType(GridAddType.FindControl("chk_Add"), CheckBox)

'as you see i want to get values of above control in this event is there any solution which i can get the values of corrosponding rows's controls

End Sub

Not in an easy way, you always call the same Handler for the TextChanged Event. While you know which TextBox initiated this, you cannot easily go to the other Controls.

You could however create a dictionary<textbox,int32> where you save the TextBoxes and the corresponding row-Index on the DataBound Event of the datagrid. So you can later on do dictionary.TryGetValue(tb). Try googling it if you don't know about dictionarys (or maps which they are usually called).

thank dear now you understand my problem thanks once again for helping me for some days.I will search dictionarys on google.
