GridView 中 RadioButton單選(後端)

基本上GridView中的AutoPostBack 事件皆可使用

前端ASPX

 1.包asp:UpdatePanel 

    <asp:UpdatePanel ID="UpdatePanel12" runat="server" >

    <ContentTemplate>

    </ContentTemplate> 

    </asp:UpdatePanel> 

2.在GridView的RadioButton裡宣告OnCheckedChanged,AutoPostBack="true"

   EX:OnCheckedChanged="opt_CheckedChanged" AutoPostBack ="true"

後端

Protected Sub opt_CheckedChanged (ByVal sender As Object, ByVal e As EventArgs)

 Try

     Dim tempRadioButton As New RadioButton

     tempRadioButton = CType(sender, RadioButton)

     Dim gvRow As GridViewRow

     gvRow = CType(tempRadioButton.NamingContainer, GridViewRow)

     If Not (gvRow Is Nothing) Then

        Dim index As Integer = gvRow.RowIndex

        For i As Integer = 0 To  GridView名稱.Rows.Count - 1

        If  i <> index Then

            If CType( GridView名稱.Rows(i).Cells(0).FindControl("RadioButton名稱"), RadioButton).Checked Then

                CType( GridView名稱 .Rows(i).Cells(0).FindControl(" RadioButton名稱 "), RadioButton).Checked = False

            End If

        End If

        Next

     End If

 Catch ex As Exception

 

 End Try

End Sub
