更新面板与图像按钮 [英] update panel with image button

问题描述

我想在我的项目中创建类似的功能，用户可以点击图片按钮来欣赏个人资料，然后再次点击以不喜欢个人资料。一切正常，但当我点击图像按钮时，它刷新整个页面。我不想刷新整个页面，所以我添加了更新面板，但页面仍然令人耳目一新。

 <   asp：ScriptManager     ID   =  ScriptManager1    runat   =  server >  
 <   / asp：ScriptManager  >  
 <   asp：UpdatePanel     ID   =  UpdatePanel1    runat   =  server < span class =code-keyword>>  
 <   ContentTemplate  >  
 <   tr  >  
 <   td     colspan   =  5 >  
 & nbsp;  <   asp：ImageButton     ID   =  btn_like    runat   =  server < span class =code-attribute>  工具提示  = 喜欢这个广告    onclick   =  btn_like_Click1    /  >  
 <   / td  >  
 <   / tr  >  
 <   / ContentTemplate  >  
 <   / asp：UpdatePanel  >  

解决方案

添加一个 AsyncPostBackTrigger 。

 <  触发器 >  
 <   asp：AsyncPostBackTrigger  < span class =code-attribute>   ControlID   =  btn_like    EventName   =  点击    /  >  
 <   /触发器 >  

I am tring to create like functionality in my project, user can click on image button to like the profile and click again to dislike the profile. Everything working fine but when i click on image button it refresh the whole page. I don't want to refresh whole page so i added update panel but still page is refreshing.

<asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
                    <ContentTemplate>
                    <tr>
                        <td colspan="5">
                            &nbsp;<asp:ImageButton ID="btn_like" runat="server" ToolTip="Like this Ad" onclick="btn_like_Click1" />                            
                        </td>
                    </tr>
                    </ContentTemplate>
                    </asp:UpdatePanel>

解决方案

Add one AsyncPostBackTrigger.

<Triggers>
    <asp:AsyncPostBackTrigger ControlID="btn_like" EventName="Click" />
</Triggers>
