why ajax modelpopup hides behind silverlight object?

Question

I have silverlight plugin on my page and some functionality to show panel as popup with the help of Ajax ModalPopup extender,

But whenever show modal pop up it hides behind the silverlight plugin i.e. plugin is always on top?

any suggestion to solve this problem?

Answer 1

Try setting isWindowsless to true when creating the silverlight object. Pass this in as a parameter. Windowsless silverlight apps have a z-index of 1 so you can overlay them. I did hear there was a performance hit mind you.
