using FindControl after ChangeMode in a FormView

pbb · March 6th, 2007, 08:27 AM

Hi all,

I think my problem lies in not being able to find controls after performing a ChangeMode on a FormView.

Much simplified code:

Code:

if (true)
{
  FormView1.ChangeMode(FormViewMode.Edit);
  Trace.Write (((TextBox)FormView1.FindControl("SomeEditControl")).Text);
}

This results in "Object reference not set to an instance of an object".

The idea is to have a FormView which is set to Edit mode when a certain datafield is NULL, and give the databound TextBox a default value retrieved from a Cookie.

How should I access the TextBox control?

Hope you can help,
Peter

Ok, we found the solution. The code was inside the FormView1_DataBound procedure, which apparently gets executed twice, and only on second try the FindControl function returns anything. So I've added a check to see if FindControl returns anything, and now everything works :-)
