asp.net Ajax 簡單案例

第一步先引用 scriptManager

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

<asp:Button ID="cmdGuangZhu" runat="server" CSSClass="ButtonWeiXin" Text="提交" OnClick="cmdGuangZhu_Click" /> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="cmdGuangZhu" /> </Triggers> </asp:UpdatePanel>

進度

<asp:UpdatePRogress ID="UpdateProgress1" runat="server" > <ProgressTemplate >

<div id="iLoading" style="font-weight: bold; font-size: large; left: 20px; text-transform: capitalize; color: red; font-family: Monospace; position: absolute; top: 50px; background-color: #99ccff;">

Loading......

</div>

</ProgressTemplate> </asp:UpdateProgress>

后臺執行事件的按鈕代碼里要加入System.Threading.Thread.Sleep(2000);
