Can you see any problems? Thanks. David Private Sub ClearForm() Dim fv As FormView = fvPeople Dim tb As TextBox For Each ctrl As System.Web.UI.Control In fvPeople.Controls If TypeOf ctrl Is TextBox Then tb = ctrl tb.Text = "" End If Next End Sub

The example I gave you was loop on a Web form not a FormView. You may still need a loop using the FormView.FindControl. http://geekswithblogs.net/azamsharp/archive/2006/05/22/79294.aspx HTH

I know how to loop through a single control like a listbox. I need to loop through all controls in a FormView. Thanks. David |
