Hi richard1970,

If you want to access the TextBoxes in multiple rows, you can loop the GridView and access it from each row:

For Each gvr As GridViewRow In GridView1.Rows
 Dim tb As TextBox = DirectCast(gvr.FindControl("TextBox1"), TextBox)
Next

You can use the same way to access any control from ItemTemplate in GridView.

Thanks,
