Re: Index Out of Bounds Error
 

Ken,

Thanks for the response. I found the problem. I didn't define a DataKey
for the Datagrid. DataKeys are required to pick up the selected row. So my
code looks like the following now:
dvPromote = New DataView(dtPromote)
dgRequests.DataSource = dvPromote
dgRequests.DataKeyField = "Tran_ID"
dgRequests.DataBind()
I didn't show this code before, but the dgRequests.DataKeyField entry was
missing.

Thanks again for your help.

Dave
