I have a few textboxes named textbox1, textbox2, etc. Is there a way to create a loop to change the text in each text box to the same thing by incrementing the number after textbox.

You could using the FindControl("controlname") method. Build the control from "textbox" and the loop counter.

I tried using FindControl() but I am getting the error Name 'FindControl' is not declared. I even copied the example from the help file and got the same error.

The code i am using is:

I responded prematurely to this thread. Are you working in a windows form? Sounds like it. That method applies to web forms. I'm not sure how you'd do this in a windows form apart from putting all the textboxes into some collection or control container so you can loop thru all of that object's members.

Try:

_______________________________________

Dim ctrl As Control
For Each ctrl In Me.Controls
   If (ctrl.GetType.ToString = "System.Windows.Forms.TextBox") Then
         CType(ctrl, TextBox).Text = "All textbox text is the same."
   End If
Next

This should get you on the right track. Modify it according to what exactly you want. With this you don't need the number, it just looks to see if the control is a textbox.

The above example is for the entire form, but you can do this for panels, groupboxes, etc., anything that is a container.

Also consider the recursion factor. If you encounter a control that contains controls, you'll need to dig into that as well. So you should write this logic into a method that can call itself if it finds controls within a control's controls collection.
