[使用c＃的页面加载问题更新面板asp.net

Question

先生，我正在制作一个论坛项目，正在使用Technology asp.net c＃和SQL数据库，其中网站网址是https://www.indiabix.info/

在主页中，我正在使用Ajax扩展（更新面板）来防止页面加载，但是当我单击“加载更多”时，会触发页面加载问题，所以先生，如何防止按钮在更新面板中单击时加载页面给我的代码

Default.aspx

<div class="col-md-8 col-sm-12">

         int finalsize = Convert.ToInt32(ViewState["num"]) + 2;
         bindrptrecentquestion(finalsize);
         ViewState["num"] = finalsize;
         countpost();
     }

先生，请为我解决感谢和问候Sachin Srivastava

Answer 1

page_load事件将在调用回发到服务器时始终执行。当button_click发生回发时，将导致执行page_load事件，此后在页面生命周期中的某个时间，将执行button_click事件。

Updatepanel阻止Web客户端执行“完全重新加载”。使用ajax，它“隐藏”服务器和客户端之间的通信，并且仅替换页面中需要更新的部分-Updatepanel中的内容。

有关页面生命周期的更多信息，请参见MSDN documentation。>>
