Iterate though all controls on asp.net page

Question

I\'m using ascx and I need to iterate through all of the controls and selects each that have cssClass attribute set to \'required\'.

I have the following code:

Answer 1

The Control class doesn't have that CssClass property, the WebControl does. So try to cast your childControl to WebControl. If that worked, then you can access the CssClass property.

WebControl webCtrl = childControl as WebControl;
if (webCtrl != null)
{
   webCtrl.CssClass = "test";
}
