Rad Window Exception: Value does not fall within the expected range for Radwindow

[Chirag]

When I opened page on image button click then I again open the page from this opened page. so controls' name are same in a Browser

Hi Chirag,

 All the RadWindows are opened in popups, so they share the same name-scope and if you open two rad windows with the same name this error will occur. To avoid this I would suggest you to not set names to the RadWindow controls.

Hope this helps.

Best wishes,
