[VB]取出Gridview的TemplateField裡面textbox checkbox的值

實作gridview表格裡，將TemplateField裡元件(textbox , checkbox)值取出。

  程式碼:
 Public Sub Get_gv_control_data()
        For Each row As GridViewRow In gv_screen_filter.Rows
            For Each cell As TableCell In row.Cells
                Dim controls As New List(Of Control)()
                'Add controls to be removed to Generic List
                For Each control As Control In cell.Controls
                    controls.Add(control)
                Next
                For Each control As Control In controls
                    Select Case control.GetType().Name
                        Case "TextBox"
                            Response.Write("<p>Text: " & TryCast(control, TextBox).Text & "/ID: " & TryCast(control, TextBox).ID & "</p>")
                            Exit Select

                        Case "CheckBox"
                            Response.Write("<p>Text: " & TryCast(control, CheckBox).Checked.ToString() & "/ID: " & TryCast(control, CheckBox).ID & "</p>")
                            Exit Select
                    End Select
                Next

            Next
        Next
    End Sub

實作結果:
列印出textbox的值與checkbox的Checked狀態和元件id

Text: False/ID: CheckBox1 

Text:q /ID: TextBox1

Text:qw /ID: TextBox2

Text: qwe/ID: TextBox3
