ASP.NET

选择“操作”会初始化对应的“下一环节处理”，
选择“下一环节处理”会初始化“备选责任人”

//public delegate void EventHandler(object sender, EventArgs e);

	public event EventHandler PreSubmit;

	// 提交前事件触发
	if (PreSubmit != null)
	{
	     EventArgs ea = new EventArgs();
	     PreSubmit(this, ea);
	}

控件使用：

<!-- 注册用户组件 -->
<%@ Register src="../../AspUC/Dispose/Dispose.ascx" tagname="Dispose" tagprefix="uc1" %>


<div>
     <uc1:Dispose ID="Dispose1" runat="server" OnPreSubmit="SaveNetworkInfo"/>
</div>
