ASP.NET中在后台用C#，往前台插入HTML代码

比如我有个tempString，里面存放了一些HTML代码，比如一个Panel以及其中所包含的一些控件。 我想在前台某个事件触发后，在后台调用一个方法往前台的某个位置（比如一个div（id="tempDiv"）结束的位置）插入这个Panel（id=“tempPanel”）。
</pre><pre class="line mt-10 q-content" name="code" style="white-space: pre-wrap; word-wrap: break-word; color: rgb(51, 51, 51); font-size: 14px; margin-top: 10px; margin-bottom: 0px; padding: 0px; font-family: arial, 'courier new', courier, 宋体, monospace; word-break: break-all; line-height: 24px; background-color: rgb(255, 255, 255);"><pre id="recommend-content-1196248935" class="recommend-text mb-10" name="code" style="white-space: pre-wrap; word-wrap: break-word; margin-top: 0px; margin-bottom: 10px; padding: 0px; font-family: arial, 'courier new', courier, 宋体, monospace; background-color: rgb(241, 254, 221);">public string outhtml(){
string html="<div>你的html代码</div>";
return html;
}
前台页面要插入处
<div><%=outhtml()%></div>
这是其中一种方法。[csharp]
