ถามเรื่องปัญหาที่เกิดจากการเรียกใช้ Event ของ Grid ครับ

Public DivisionId As String
Public RecNo As Integer

 Private Sub dgv_CellDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgv.CellDoubleClick
        If dgv.Rows.Count = 0 Then Exit Sub
        With dgv
            DivisionId = GetString(.Rows(e.RowIndex).Cells(0).Value.ToString)
            RecNo = e.RowIndex
            Me.Dispose()
        End With
    End Sub

    Private Sub btnSelect_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSelect.Click
        dgv_CellDoubleClick(sender, e)
    End Sub
