要疯了，求救，UpdatePannel里的按钮失效。

Question

写的一个功能是文章评论，按钮是在一个div层里面的，单击评论，显示一个层，层里是评论内容，和提交评论按钮。现在按钮第一次单击的时候正确的，但是在单击就没效果了，直接没反应了，搞了一晚上也没看出是哪里错了，麻烦大家看下了，搞死我了。//Aritical.aspx

Answer 2

<Triggers    >        <asp:AsyncPostBackTrigger ControlID="BtnCommite" EventName="Click" />    </Triggers>protected void BtnCommite_Click(object sender, EventArgs e)
        {
            if (TxtContent.Text.Trim().Length <= 0)

            }
        }

Answer 3

在UPDATEPANEL中添加
]<Triggers ><asp:AsyncPostBackTrigger ControlID="BtnCommite" EventName="Click" /></Triggers>后台代码：protected void BtnCommite_Click(object sender, EventArgs e)
{
if (TxtContent.Text.Trim().Length <= 0)
{
MessageBox("提示", "评论信息不完整！");
}
else
{
this.UpdatePanel1.Update();
}
}

Answer 4

搞定了，谢谢各位了。从ff中查看到，
第一次提交的地址是Aritical.aspx?id=91,第二次单击就变成Aritical/Aritical.aspx?id=91很奇怪，把所有控件都删了，只留提交，还是错误。最后定为到URLReWriter里，原来是这个错误，
我默认将Aritcal/91.html映射为Aritical.aspx?id=91改成Aritical_91.html的映射就OK了。
搞死了，
不过还是没明白为什么？？？
