Clicking on ReportViewer after selecting check boxes from RadComboBox does not cause a post back if the report is in a control.

How can I make a RadComboBox cause post back when click in the report area, but only if something actually has changed in the RadComboBox?

I have 1 control with multiple rad combox with post back set to true.

I have another control with a ReportViewer.

If the reports isn’t loaded the post back works, but if a report is loaded there is no post back caused by the RadComboBox selecting in to the report viewer AREA.
