How do you determine if an entire row is empty?

The code below is not working well.  Even if there is one row of data it has two blocks of text output.

                If IsDBNull(datagrid1.Item(0, r).Value) = False And IsDBNull(datagrid1.Item(1, r).Value) = False And IsDBNull(datagrid1.Item(2, r).Value) = False And IsDBNull(datagrid1.Item(3, r).Value) = False And IsDBNull(datagrid1.Item(4, r).Value) = False Then
                    strTransportSequence &= CurRowStr & "     ==============================" & vbCrLf
                End If



            For r As Integer = 0 To datagrid1.Rows.Count - 1
                Dim CurRowStr As String = ""
                CurRowStr = CurRowStr & "     Test1 : " & datagrid1.Item(0, r).Value & vbCrLf
                CurRowStr = CurRowStr & "     Test2 : " & datagrid1.Item(1, r).Value & vbCrLf
                CurRowStr = CurRowStr & "     Test3 : " & datagrid1.Item(2, r).Value & vbCrLf
                CurRowStr = CurRowStr & "     Test4 : " & datagrid1.Item(3, r).Value & vbCrLf
                CurRowStr = CurRowStr & "     Test5 : " & datagrid1.Item(4, r).Value & vbCrLf
                If IsDBNull(datagrid1.Item(0, r).Value) = False And IsDBNull(datagrid1.Item(1, r).Value) = False And IsDBNull(datagrid1.Item(2, r).Value) = False And IsDBNull(datagrid1.Item(3, r).Value) = False And IsDBNull(datagrid1.Item(4, r).Value) = False Then
                    strTransportSequence &= CurRowStr & "     ==============================" & vbCrLf
                End If
            Next

If I've understood correctly, what you want is this

            For r As Integer = 0 To datagrid1.Rows.Count - 1
                Dim CurRowStr As String = ""
                If IsDBNull(datagrid1.Item(0, r).Value) = False And IsDBNull(datagrid1.Item(1, r).Value) = False And IsDBNull(datagrid1.Item(2, r).Value) = False And IsDBNull(datagrid1.Item(3, r).Value) = False And IsDBNull(datagrid1.Item(4, r).Value) = False Then
                    strTransportSequence &= CurRowStr & "     ==============================" & vbCrLf
                Else
                    CurRowStr = CurRowStr & "     Test1 : " & datagrid1.Item(0, r).Value & vbCrLf
                    CurRowStr = CurRowStr & "     Test2 : " & datagrid1.Item(1, r).Value & vbCrLf
                    CurRowStr = CurRowStr & "     Test3 : " & datagrid1.Item(2, r).Value & vbCrLf
                    CurRowStr = CurRowStr & "     Test4 : " & datagrid1.Item(3, r).Value & vbCrLf
                    CurRowStr = CurRowStr & "     Test5 : " & datagrid1.Item(4, r).Value & vbCrLf
                End If
            Next
