What if multiple TargetControls for the ModalPopup?
A ModalPopup doesn’t allow this natively, but it’s still possible to achieve by manipulating the modalpopup control with javascript directly. Let’s say there are two buttons(btnA, btnB) to be set as the target control. 1. We set btnA to be the target control with modalpopup’s TargetControlID. 2. Assign a behaviorID to modalpopup. 3. Attach the following javascript function as the click event handler to btnB. function onClick() { $find(“behaviorIDofModalPopup”).
