给你说明白点

//在
private void InitializeComponent()
{
//加上下面这句话
this.NetPage.PageChanged += new Wuqi.Webdiyer.PageChangedEventHandler(this.NetPage_PageChanged);
//其中NetPage改为你给控件起的名字
}

这样你点击页面才会变不然只会第一页还有就是你把控件剪贴移动位置这句都要写过~~~

在
private void InitializeComponent()
{
//加上下面这句话
this.NetPage.PageChanged += new Wuqi.Webdiyer.PageChangedEventHandler(this.NetPage_PageChanged);
//NetPage为控件名字
}
