How do you call the AJAX modal extender control when a selected value of a dropdoown list has changed?
I'm currenlty working on a page where once the user selects a certain value from the dropdownlist, I need to display an AJAX Modal window for them to input information. Can somone provide the syntax for calling the modal popup when the dropdowns selected value is changed to a number i specify. Currently i have set the TargetControl to a hidden button, and on the SelectedIndexChanged event I'm using modal1.Show(), but nothing happens.
