I have a ModalPopupExtender and a ConfirmButtonExtender in a user control that is being referenced on a parent page. The parent page performs a partial postback and if a condition is false, I call .Show() on the modal popup.
If the user clicks "Yes" I want to fire another event on the parent page. I'm passing delegates to the user control to be invoked in the button click event handlers in the code behind of the control. However, the buttons of the modal dialog don't trigger the server side onclick events. It's like something in the ajax framework simply closes the dialog and suppresses the postback.
I've tried explicitly firing the postback from javascript, to no avail.
