If it were me, I would find a way to loop through the table rows, find the control, an object, I was looking for on the row using FV.FindControl(), and address the object's properties. Having not worked with a FV, I would suspect that is the way it must be done. The example provided shows you how to find the control on the FV. It's up to you to think outside of the box and find a way to implement the solution to address the problem.

I got my code to work ok now. I was setting the FormView control to visible=False and it did not work. I changed it to a CSSClass that was hidden and it worked. Below is my finished code, if interested. Private Sub ClearForm() Dim tb As TextBox Dim ctrl As Control For Each ctrl In fvPeople.Controls If TypeOf ctrl Is TextBox Then tb = ctrl tb.Text = "" End If Next End Sub

That is because when any server-side's control's Visible property is set to "false", it doesn't actually get rendered in the HTML streamed down to the client... -- Mark Rae ASP.NET MVP http://www.markrae.net |
