สอบถามการเปลียบเทียบ DataGridView1 และ DataGridView2 เพื่อเพิ่มข้อมูล

  Private Sub DataGridView1_CellEndEdit(sender As Object, e As DataGridViewCellEventArgs) Handles DataGridView1.CellEndEdit
        For r As Integer = 0 To Me.DataGridView2.Rows.Count - 1
            If Me.DataGridView1.CurrentRow.Cells(2).Value = Me.DataGridView2.Rows(r).Cells(1).Value Then
                Exit Sub
            End If
        Next
        Dim x As Integer
        x = Me.DataGridView2.Rows.Count
        Me.DataGridView2.Rows.Add()
        Me.DataGridView2.Rows(x).Cells(0).Value = "Bar"
        Me.DataGridView2.Rows(x).Cells(1).Value = "Bar"
        Me.DataGridView2.Rows(x).Cells(2).Value = "Bar"
        Me.DataGridView2.Rows(x).Cells(3).Value = "Bar"
        Me.DataGridView2.Rows(x).Cells(4).Value = "Bar"
        Me.DataGridView2.Rows(x).Cells(5).Value = "Bar"
        Me.DataGridView2.Rows(x).Cells(6).Value = "Bar"
        Me.DataGridView2.Rows(x).Cells(7).Value = "Bar"
        Me.DataGridView2.Rows(x).Cells(8).Value = "Bar"
        Me.DataGridView2.Rows(x).Cells(9).Value = "Bar"
        Me.DataGridView2.Rows(x).Cells(10).Value = "Bar"
    End Sub

  x = Me.DataGridView2.Rows.Count
