Howto? Prevent Popup Container from hiding

How can the popup container be prevented from closing. I am using the popup container to show more advanced options some of which need to be validated. TIA,

Peter, The PopupControlContainer is more menu-like than dialog-like and hence it doesn't support dialog like validation. When the user clicks else where the popup will have to closup like a menu. In case you are not already aware, you could listen to the popup's CloseUp event and determine whether or not the popup was cancelled. Regards, Praveen
