test.aspx.cs代码
private void Page_Load(object sender, System.EventArgs e)

Label1.Text += "<INPUT type=button value=Button id=Button1 name=Button1 runat=server>";
}
public void Button1_ServerClick(object sender, System.EventArgs e)
{
事件代码……
}
这样点击按钮，无任何反应
请问这个方法能触发事件吗？要怎么修改
还有别的好方法在label中加入按钮，能触发事件的吗？
"<INPUT type=button value=Button id=Button1 name=Button1 Onserverclick=Button1_ServerClick runat=server>";
<form id="Form1" method="post" runat="server">
"<INPUT type=button value=Button id=Button1 name=Button1 Onserverclick=Button1_ServerClick runat=server>
</form>
Label1.Text += "<INPUT type=button value=Button id=Button1 name=Button1 runat=server />";
注意倒数第四个字符
用panel这个容器控件吧，label不是个容器控件

如果是程序中本身就写好的
<asp:button id=btn1 runat=server text=wo1 onclick=btn1_click />
那执行起来是没问题的
但通过
Label.Text 赋值出来的按钮，它在
<input type="hidden" name="__VIEWSTATE" ..
里没有注册上，系统不知道该去执行哪一个服务端事件
同意 cmsoft(韦小宝是我的老乡.net)
panel好用
private void Page_Load(object sender, System.EventArgs e)
{
Label1.Text += "<INPUT type=button value=Button id=Button1 name=Button1 Onclick=Button1_ServerClick runat=server>";
}
Button1_ServerClick 写在html中
