        Dim chk As CheckBox = TryCast(sender, CheckBox)

        If chk.ID = "CheckBox2" Then
            For Each item As RadComboBoxItem In RadComboBoxEmp1_ID.Items
                '  If item..RowType = DataControlRowType.DataRow Then

                item.Controls.OfType(Of CheckBox)().FirstOrDefault().Checked = chk.Checked

                ' row.Cells(2).Controls.OfType(Of RadComboBox)().FirstOrDefault().Visible = False
                '   End If
                TextBox1.Text += "'" & item.Value & "',"


            Next



        End If

        For Each item As RadComboBoxItem In RadComboBoxEmp1_ID.Items

            DirectCast(item.FindControl("CheckBox1"), CheckBox).Checked = chk.Checked
            If DirectCast(item.FindControl("CheckBox1"), CheckBox).ID <> "CheckBox1" Then
                chk.Checked = False
            End If
            '  chk.Checked = False
            ' Dim chk As CheckBox = TryCast(sender, CheckBox)
            ' If chk.Checked = True Then
            TextBox2.Text += DirectCast(item.FindControl("CheckBox1"), CheckBox).ID & ", "
            'End If
            If DirectCast(item.FindControl("CheckBox1"), CheckBox).Checked = True Then
                DirectCast(item.FindControl("CheckBox1"), CheckBox).Checked = True
                TextBox2.Text += DirectCast(item.FindControl("CheckBox1"), CheckBox).ID & ", "
