微軟內建AJAX的用法

 

首先下載一個ASPAJAXExtSetup,安裝後產生的AjaxControlToolkit.dll放到ui裡的bin檔案夾裡.接下來就可以用了.

<asp:ScriptManager ID="ScriptManagerUser" EnablePageMethods="true" runat="server" />

<asp:UpdatePanel ID="UpdatePanel1" runat="server"><ContentTemplate>

非同步重新整理的內容

</ContentTemplate>

    <Triggers>

<asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" />        <asp:AsyncPostBackTrigger ControlID="DropDownList1" EventName="SelectedIndexChanged" />

      <asp:AsyncPostBackTrigger ControlID="CheckBox1" EventName="CheckedChanged" />

    </Triggers>

</asp:UpdatePanel>

//注意ControlID是觸發控制項的id,而DropDownList1的觸發是OnSelectedIndexChanged="dropDistrict_SelectedIndexChanged",觸發後是運行cs裡的dropDistrict_SelectedIndexChanged段.而CheckBox1的觸發是

OnCheckedChanged="CheckBox1_CheckedChanged"觸發後是運行cs裡的CheckBox1_CheckedChanged段.

總結: EventName是控制項的Click的一部分,如Click(OnClick);

SelectedIndexChanged(OnSelectedIndexChanged);

CheckedChanged(OnCheckedChanged).
