首先，你必须启用ScriptManager的历史EnableHistory =真
在这个例子中，我们维修器材gridview的分页，当用户浏览器后退按钮 你有你的网页第一次加载后添加历史点。

First of all you have to Enable ScriptManager history EnableHistory="true"
In this example we are maintaing gridview paging, When user browser back button You have add history point after your page first time loads.

private void AddHistoryPoint(String key, String value, String tile)
{
    ScriptManager scm = ScriptManager.GetCurrent(this.Page);
    if ((scm.IsInAsyncPostBack == true) && (scm.IsNavigating != true))
    {
        if (pageState == null)
        {
           NameValueCollection pageState = new NameValueCollection();
        }
        if (pageState[key] != null)
        {
            pageState[key] = value;
        }
        else
        {
            pageState.Add(key, value);
        }
        scm.AddHistoryPoint(pageState, tile);
    }
}

protected void grid_PageIndexChanged1(object sender, EventArgs e)
{
    AddHistoryPoint("pi", grdProject.PageIndex.ToString(), "Page Index- " + (grdProject.PageIndex + 1).ToString());
}

在这里你必须处理的ScriptManager导航事件

here you have to handle ScriptManager Navigate Event

     protected void ScriptManager1_Navigate(object sender, System.Web.UI.HistoryEventArgs e)
{
    if (e.State != null)
    {
        if (e.State["pi"] != null)
        {
            grid.PageIndex = Convert.ToInt32(e.State["pi"]);
        }
    }
}
