After applying the CSS styles from my previous response, then the RadWidnow
's content page will appear only. This means that you can declare a handler and catch the click events on that page. For example this code will catch any click on the content document :
| document.onclick = function()
| alert("Popup1.aspx is clicked");
Once again, add this code to the head tag of the page that is opened inside the RadWindow and an alert box will appear every time you click the RadWindow.
For your convenience I have attached the reworked project from my previous response.
I hope this helps.
