User controls and validation
Goal: Combine radio group and drop down listbox. If option one of the radio group is selected, then require a selection from the drop down list box. If option 2 of the radio button is selected, disable the drop down listbox or ignore.
If I create a user control combining a radio group and a listbox can I validate values in both controls with the standard validation tools? E.g. checking that value from drop down listbox selected when option 1 of radio group selected.
I do not want to use custom validators because of difficulty getting the client side script to work with master pages.
