非使用FindControl方法找到深层嵌套的控件

首先看下示意图
View Code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Insus.NET;

public partial class MasterPage : System.Web.UI.MasterPage
{
protected void Page_Load(object sender, EventArgs e)
{

}

protected void ButtonGet_Click(object sender, EventArgs e)
{
IGetable obj = (IGetable)IterationFindControl(this, "WebUserControl1");
this.LabelResult.Text = obj.GetObject().ToString ();
}
}

演示源程序(asp.net 4.5 + C#)：
