Index was out of range. Must be non-negative and less than the size of the collection

[seep]

hi to all.

i m finding this exception in the following code but unable to understand ..

Protected Sub GridView1_RowDeleting(ByVal sender As Object, ByVal e As GridViewDeleteEventArgs)
       [B] Dim opd_sr As Integer = CInt(Gridview1.DataKeys(e.RowIndex).Value.ToString)[/B]       
        outTicketDetail.DeleteCommand = "Delete"
        outTicketDetail.DeleteCommandType = SqlDataSourceCommandType.StoredProcedure
        outTicketDetail.DeleteParameters.Add("@opd_sr", TypeCode.Int32, opd_sr.ToString())
        'outTicketDetail.Delete()
      opd_sr.ToString

    End Sub

at bold line i find error.

What does Gridview1.DataK eys(e.RowIndex) .Value.ToString return?

[seep]

it should return the primary key of that row i.e opd_sr. but at this point i m finding exception of "Index was out of range. Must be non-negative and less than the size of the collection."

I notice you said should, what debugging have you tried?

What does Gridview1.DataK eys(e.RowIndex) .Value.ToString return?

I'd be interested in knowing the size of DataKeys vs the size of e.RowIndex.
If you could print those before the guilty statement is reached ...
