Hi

I am currently trying to create a function to count the number of rows held in a DataTable however I keep getting an Object reference not set to an instance of an object error

 Function itemcount() As Integer


        Dim itemcounter As Integer = 0

        For Each Me.objDR In objDT.Rows
            itemcounter = itemcounter + 1
        Next

        Return itemcounter

    End Function

Open in new window


Can anyone help with this please?

Why not just use objDT.Rows.Count.ToString instead of using a foreach?

I agree that you should really use the Count method.


>>For Each Me.objDR In objDT.Rows

your iterator (objDR) should be a new variable:

For Each dr as DataRow In objDT.Rows
0
