No Source Available using the ModalPopupControl

Hi,

Earlier I put a post in the forum for gridview and other data controls regarding the SlectedIndexChanged not firing.

However I am using an Ajax ModalPopupControl to display data. This control might be my problem and not so much the other controls.

When I try to debug the code behind I get the "No Source Available" error message.

This is confusing because if I run the app no error messages and I do see data populating in my DataList control, but I can't select a new record to view.

Any solutions on why I am getting this "No Source Available" message?
