Data Bind() but when I do that it doesn't refresh the drop down list, it adds a SECOND set of items to the list which is just odd...but that's another battle for another day I suppose.In a recent tip on Language INtegrated Query (LINQ), you have described how it can be used as a query language extension to both VB.
