I am using a modalpopup as my "details view" for a gridview.   I display the dialog using javascript.

I set up some cascading dropdownlists in the modalpopup...and I pre-populate the values based on the row selected from the gridview using client side javascript.

It works the first time, but if I hit Cancel (also done client side in javascript) and close the modaldialog -- the next time I run the webservice, set the contextKey, the dropdownlist shows with the previous selected value.

How can I refresh a modalPopup back to the initial state using javascript?
