I am creating a new instance of a popup and then adding the OnClientResize,
popup = window.radopen(Url,
popup.OnClientResize = OnClientResize();
When the popup opens/loads the function is fired, however it is never fired again when resizing.
However, if i add it to the radwindowmanager, and assign the same function to it, it will work every time.
I do not wish to add it it to the radwindowmanager as the function i need to call is not available on that page.
Any help with this would be much appreciated.
