Triggering an Update Panel from a control in a different ContentPlaceHolder
I can across an anamoly today when I tried to trigger an Update Panel from a control in a different ContentPlaceHolder. The IDE recognized the control in the designer as I was able to select the control ID from the dropdown. But, when I ran the page I received an error stating: "A control with ID 'Button1' could not be found for the trigger in UpdatePanel 'UpdatePanel1'."
