Can't access controls inside a formView

[Andy B]

I have 2 TextBoxes and a Label inside the EditItemTemplate of a formView
(the EditItemTemplate is the only template it has). I need to access the
properties of the Label and TextBox controls elsewhere on the page. How do
you do something like that? I tried probably just about everything I can
think of. I tried this line of code but I keep getting a null reference
exception.

Label DateConfirmLabel =
(Label)EditNewsForm.Controls[0].FindControl("DateLabel");



The really strange thing, this worked when I needed my Menu from the
masterPage:



Menu MainMenu = (Menu)this.Master.FindControl("MainMenu");



Then I could access the MenuItems normally. Help!





The FormView is inside a wizard.

Hello Andi,
if the controls resides in a content page (connected to a Masterpage) then
the id's changing to something like
ctl00$ContentPlaceHolder1$label.
to see what's happens enable trace in the page directive.

Kind Regards

Anthony

Depending what template is the default at the time of call, one of these
should work:

Label DateConfirmLabel = (Label)EditNewsForm.FindControl("DateLabel");

or

Label DateConfirmLabel =
(Label)EditNewsForm.EditItemTemplate.FindControl("DateLabel");

When I use EditNewsForm.Controls.Count I get 1 for the answer (probably
because of EditItemTemplate). When I do EditNewsForm.Controls[0].Count I get
3 for an answer (the Label and 2 TextBoxes). Since I figured this much out,
I thought I could use EditNews.Controls[0].Controls[0] for the Label and
EditNews.Controls[0].Controls[1]/[2] for the TextBoxes. When I actually Used
the EditNewsForm.Controls[0].Controls[0] I ended up with index out of range
error. How can that be when there are 3 controls inside of Controls[0]?

Any detailed help on how to get to these controls...

Both of those fail as well... keep coming up with a null object reference...
could all this trouble be because the formview is inside a wizard?

Label DateConfirmLabel = (Label)EditNewsForm.FindControl("DateLabel");

or
