Ensure you have a valid RowIndex
And try using a GridViewRow as follows;
Dim gvrEdit as GridViewRow = gridView1.Rows(e.RowIndex)
Dim txtBox as TextBox = DirectCast(gvrEdit.FindControl("txt_Name"), textBox)
Additionally, ensure that in your RowEditing event handler make sure you set the gridView1.EditIndex

Kind Regards

Please always reply to a comment as the author receives a notification.
If FindControl does not return your control then the ID you are using is incorrect. If you load the page in a browser window & then view the source you can see what the actual control's ID is.
Alternatively use your debugger, in your RowUpdating event handler get the GridViewRow & look at what controls it contains using the "Locals" window.
This should allow you to identify the actual controls that are contained on your row

Kind Regards
