推荐答案

我有同样的问题和解决的方法很简单。

I had the same problem and the solution is very simple.

第一步是包括DataPager控件和网页上的定时器控制。

The first step is to include a DataPager control and a Timer control on your page.

<asp:DataPager ID="pager" runat="server" PagedControlID="listView" PageSize="10">
    <Fields>
        <asp:NumericPagerField ButtonType="Link" />
    </Fields>
</asp:DataPager>

<asp:Timer ID="timer" runat="server" Interval="1000" OnTick="timer_Tick">
</asp:Timer>

接下来，你必须写这篇code：

Next, you must be write this code:

protected void timer_Tick(object sender, EventArgs e) {
    //Verify that the session variable is not null
    if (Session["startRowIndex"] == null)
        Session.Add("startRowIndex", 0);
    //Create a variable to store the first record to show
    int startRowIndex = Convert.ToInt32(Session["startRowIndex"]);
    //Show from the first record to the size of the page
    this.pager.SetPageProperties(startRowIndex, this.pager.MaximumRows, true);
    //Increase the first record to display in the size of the page
    startRowIndex += this.pager.MaximumRows;
    //If the first record exceeds the total number of records, restart the count.
    if (startRowIndex > this.pager.TotalRowCount) startRowIndex = 0;
        Session["startRowIndex"] = startRowIndex;
}

，并把这个code在Page_Load事件：

And put this code in the Page_Load event:

protected void Page_Load(object sender, EventArgs e) {
    //This session variable to control the record to show for each tick
    if (!IsPostBack) Session.Add("startRowIndex", 0);
}

我希望你成为的东西，如果它不是太迟了，对不起我的英语水平，因为它不是我的母语。

I hope you serve something, if it's not too late, and sorry for my English, because it is not my native language.
