There is a javascript function registered for ValueChanged event, and it is used with Ajax ModalPopupExtender.
When user clicks on a date from the data chooser, the function might need to display the Modal dialog asking for user input. Here comes the problem:
1. If I do not cancel the event, the modal displays and closes immediately.
2. If I cancel the event, the model displays, but the event is lost.
So is there any way WebDateChooser can work with ModalPopupExtender in this case?
