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.
