ListBox

Jacob Button asked on 29 Sep 2009, 03:25 PM

I'm having a problem which, for the life of me, I can't figure out.

I have a listbox ( ID: CommentsListBox ) inside of a splitter control. The listbox should be getting it's data from a SqlDataSource ( ID:CommentsDataSource ), but it seems it wont bind to the datasource, the code never actual executes the Comments_ItemDataBound method. I have no idea why. I know the select command for the sql datasource is good, it executes just fine in sql server and does return results. Please help.
