Thread: Collection of Form Controls

I'm not sure what the problem is, R. The method I provided works fine for me from a Web Form when in a Master Page. It also works for me when being called from a UserControl inside a Web Form inside a Master Page.

Referencing back to your foreach loop example, an easier way to ensure the control is a TextBox (for example):

Code:

TextBox tb = ctl as TextBox;
if (tb != null) {
   // It's a text box, so do textboxy things to it.
}

Otherwise, if you want to disable all the disable-able controls then the following loop takes advantage of these Controls inheriting from WebControl. (tho this is untested):

Code:

foreach (Control ctl in Form.Controls) 
{
   WebControl webctl = ctl as WebControl;
   if (webctl == null) continue;
   webctl.Enabled = false;
}

I was just on that idea Wolffy!

I just changed a <div> to a, <aspanel> and have looped through the controls inside that and it worked.

Will have a look at the code you posted and try that out as well. Not sure if a blanket .Enabled=false will work, but I'll see what happens..

Strange. I just did a test writing out each control type it found when called from my web form and it just wrote out the controls from the master page, including the ContentPlaceHolder.

It's not just textboxes, it's all form web controls, textbox, dropdown etc.

Got something working but will play around some more and see what I come up with.

I tried this and it almost worked, but just messed up the text on a checkboxlist that is inside a repeater.

I also tried this and it worked apart from not disabling the checkboxlist boxes inside the repeater...
