Using <asp:hidden> fields on RadWindows

[David Robbins]

Are the <asp:hidden> fields I have assigned to asp.net form inaccessible when I load that window as a child window with RadWindowManager?

When loaded on its own, my form can access the hidden fields using the getElementById() method.  However, when the form is launched as a Popup window with RadWindowsManager null is returned when the same script is executed.  Is this an ASP.Net issue, or do I need to do something differently clientside, such as obtain the RadWindow first via the API.  Thanks in advance.

Hi David,

The RadWindow is actually an IFRAME element and you should work with it as with such. This being said, if you want to access any controls which are placed in a RadWindow's content page from the main page you should first reference the window object of the content page, e.g.

function CallFn()
{
  var oWnd = GetRadWindowManager().getWindowByName( "RadWindow1");
  oWnd.get_contentFrame().contentWindow.CalledFn();
}

where this function is placed on the main page and the CalledFn is on the RadWindow's content page. You can find a more detailed information about this here.
