From: Dave on 2 Jun 2010 07:40 I recently adopted the SQLSiteMapProvider that Jeff Prosise wrote about at http://msdn.microsoft.com/en-us/magazine/cc163787.aspx#S1. I made 1 change though. Instead of the SQLCommand that he has in the article I changed it to a parameterized Stored Procedure that's based on a user selection from a DropDownList. It works fine for the first selection, from nothing to something, but it doesn't refresh the TreeView if a user changes the DropDownList. What do I need to do to clear out and refresh the TreeView/ SQLSiteMapProvider?
