Modeless Dialogs

Ok, here is my latest problem. I have a requirement which entails the user being able to open one or many new windows each of which relates to the entity in the main window and will contain web pages to add or dispay data (e.g add a new contact). When the main winodw closes each of these sub windows must autoamtically close.<br><br>I can get just about everything done using showmodelessdialog to create the sub windows except for one thing - closing them.<br><br>To update the database with the new information entered I need to web form controls but I cannot get them to close the dialog window after the update without opening a new version of the form in a new browser window. Adding an attribute with Window.close() works fine except when the page is opened in a modeless dialog.<br><br>Anybody come accros this or got a soloution?<br><br>Cheers
