1. I have two grid-views on a page both bound to an sqldatasource. The first gridview (GVMonthReport) displays data from a table
  2. My goal is to select a row from GVMonthReport to filter three items (Location, Trans_Budget_Code, Transaction Date) in the other table(GridView2) sqldatasource.
  3. The problem is as following: I can use one of the filtering items (Location or Trans_Budget_Code) and GridView2 filters accordingly, both work. However when i try both Location and Trans_Budget_Code together as filters nothing shows on GridView2. I can manually put the values into GridView2s sqldatasource for Trans_Budget_Code and Location and the results are what i expect. Why does that work but not when i select a row in GVMonthReport.
  4. I think it has something to do with the GVMonthReports DataKeyNames ("Trans_Budget_Code,Location"). But so far i have had no luck. Trans_Budget_Code and Location are not primary keys is that the problem?
