Hi. Would anybody know why I am getting an error when I try to access the property builder for a RadGrid. It did work fine but doesn't work now. I have deleted the old page and tried to start from scratch with a new form (based on a master page). I create the new form, add the RadGrid, use the smart tag to create an sqldatasource and then click "open property builder". I get the visual studio error:
"Error invoking 'Open Property Builder'. Details:
Exception has been thrown by the target of an invocation."
