将你的Lv的databind的代码放到：
protected override void OnPreRender(EventArgs e)
{
base.OnPreRender(e);
List<NewsItem> data = new List<NewsItem>();
data.Add(new NewsItem { ID = 1, Title = "test1" });
data.Add(new NewsItem { ID = 2, Title = "test2" });
data.Add(new NewsItem { ID = 3, Title = "test3" });
this.Lv.DataSource = data;
this.Lv.DataBind();
}

注意，无论是否是PostBack, 都要绑定
