Hi, i have question about update panel and triger asociated with it.

//update panel and repeater control
<asp:updatepanel ID="updReater" runat="server">
  <contenttemplate>
     here is my repeater control
  </contenttemplate>
</asp:updatepanel>

推荐答案

假设您的页面上有ID为ScriptManager1的scriptmanager，请在Page Load事件中编写以下代码：

Suppose you have scriptmanager with ID "ScriptManager1" on your page, write the following code in Page Load event:

ScriptManager1.RegisterAsyncPostBackControl(usercontrol1.FindControl("Button1"));//Button1 is the ID of button inside your user control.

此外，您应该将更新面板的UpdateMode属性设置为Conditional。

Also, you should set "UpdateMode" property of the update panel to "Conditional".

那么，您可以使用触发器为您的更新面板&做有需要。

我只是在下面添加触发代码：

Well, you can use a Trigger for your Update Panel & do the Needful.
I''m just adding the Code for Trigger below:

<asp:updatepanel id="updReater" runat="server">
   <contenttemplate>
      Here is your repeater control
   </contenttemplate>
   <triggers>
      <asp:asyncpostbacktrigger controlid="Button1" eventname="Click" />
   </triggers>
</asp:updatepanel>

在上面的代码行中我是将您的按钮ID视为Button1&针对异步回发定位''点击''事件。



所以只需添加以下几行Code&你的工作将完成。

In the above lines of code I''m considering your Button Id as ''Button1'' & Targeting it''s ''Click'' event for Async Postback.

So Just add these few lines of Code & your job will be done.
