Hi,<BR><BR>I have a child-window in which users can update values in a dropdownbox. When they are finished they should be able to close it and the results of the update should be available in the parent-window. The question is: how can this be accomplished. I need to call a function in Parent.aspx.cs to update the dropdownlist when the Child.aspx closes.<BR><BR>Any ideas?<BR><BR>Thanks,<BR>Maarten
