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.

Hi Erik,
The report is within an iframe and the focus cannot be moved from the container to the iframe content. Click above the toolbar or anywhere beside the report, and the combo will lose the focus, then postback :) The iframe is autogenrated and injecting scripts or etc hacks to catch the keydown are not good idea.
