數據源選擇命令不會改變單選按鈕列表

Question

因此，根據radiobuttonlist中選擇什麼，我希望選擇命令改變我的數據源。我面臨的問題是，如果我設置的默認選中的單選按鈕查詢將針對

我的單選按鈕列表，用戶（下拉列表都位於一個更新面板的按鈕後未更新工作被點擊

這是我的按鈕代碼

If user.Text = "ALL" Then 
        SqlDataSource22.SelectCommand = "SELECT * FROM [dashboardtasks] WHERE [completed] = 'NO'" 
        SqlDataSource23.SelectCommand = "SELECT * FROM [dashboardtasks] WHERE (([agent] = @agent) AND (([completed] = 'YES') or ([completed] = 'XL')))" 
       Else 
        If RadioButtonList1.SelectedIndex = 0 Then 
         SqlDataSource22.SelectCommand = "SELECT * FROM [dashboardtasks] WHERE (([agent] = @agent) AND ([completed] = @completed))" 
         SqlDataSource23.SelectCommand = "SELECT * FROM [dashboardtasks] WHERE (([agent] = @agent) AND (([completed] = 'YES') or ([completed] = 'XL')))" 

        ElseIf RadioButtonList1.SelectedIndex = 1 Then 
         SqlDataSource22.SelectCommand = "SELECT * FROM [dashboardtasks] WHERE (([agent] = @agent) AND ([completed] = @completed) and tasktype = 'Air')" 
         SqlDataSource23.SelectCommand = "SELECT * FROM [dashboardtasks] WHERE (([agent] = @agent) AND (([completed] = 'YES') or ([completed] = 'XL')) and tasktype = 'Air')" 
        End If 
       End If 

    UpdatePanel1.Update() 
     UpdatePanel2.Update() 





<asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> 
           <asp:UpdatePanel ID="UpdatePanel5" runat="server" UpdateMode="Conditional"> 
            <ContentTemplate>

              <asp:DropDownList ID="ddivision" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ddivision_SelectedIndexChanged"> 
            <asp:ListItem Selected="True">All</asp:ListItem> 
            <asp:ListItem Value="A">Club ABC</asp:ListItem> 
            <asp:ListItem Value="B">ABC Destinations</asp:ListItem> 
           </asp:DropDownList> 
           <asp:DropDownList ID="userslist" runat="server" Height="20px" Width="184px"></asp:DropDownList> 
         <asp:Button ID="updatediary" runat="server" Text="Update" /></asp:Panel> 
           <asp:RadioButtonList ID="RadioButtonList1" runat="server" RepeatColumns="5" > 
            <asp:ListItem>All</asp:ListItem> 
            <asp:ListItem Selected="True">Land</asp:ListItem> 
            <asp:ListItem>Air</asp:ListItem> 
            <asp:ListItem>Cruise</asp:ListItem> 
           </asp:RadioButtonList> 
            </ContentTemplate> 
            <Triggers> 
             <asp:AsyncPostBackTrigger ControlID="ddivision" /> 
            </Triggers> 
           </asp:UpdatePanel>

我敢打賭，你的radiobuttonlist不在updatepanel，這就是爲什麼沒有被刷新過。要更新radiobuttonlist，你需要把它放在一個updatepanel。

您需要指定控件的事件名稱：Event="SelectedIndexChanged"

<Triggers> 
    <asp:AsyncPostBackTrigger ControlID="ddivision" Event="SelectedIndexChanged" /> 
</Triggers>
