I'm trying to use a RequiredFieldValidator with a TextBox that has a jQuery UI DatePicker attached to it. I'm finding that selecting a date from the datepicker does not trigger the RequiredFieldValidator to recognize that a value is now present. Thus, only server side validation is working for the RequiredFieldValidator and not client side. Any ideas on how I may fix this issue so both client side and server side validation fires?
Below is some sample code of this issue. To reproduce this situation: 1) Click the PostBack button (RequiredFieldValidator will indicate field is required) 2) Pick a date using the date picker 3) Notice that the RequiredFieldValidator's text still displays when it shouldn't.
