Anthem.NET 的回调流程图
下面用一个最简单的 anthem:Button 回调作为例子，理清回调过程中执行函数的次序。
代码如下：
后台代码：

<form id="form1" runat="server">

<anthem:Button ID="btn1" runat="server" Text="按钮1" OnClick="btn1_OnClick"
PreCallBackFunction="btn1_PreCallback"

后台代码：
protected void btn1_OnClick(object sender, EventArgs e)
{
Anthem.Manager.AddScriptForClientSideEval("alert('script for eval')");
throw new Exception("error message");
}
{
Anthem.Manager.AddScriptForClientSideEval("alert('script for eval')");
throw new Exception("error message");
}
其流程图如下：
