C# AsyncPostBackTrigger Gridview分页

我对ASP C非常陌生，我想知道如何在AsyncPostBackTrigger中控制gridview分页。。这是我的密码：

  <div id="grid_layer">
      <asp:UpdatePanel ID="UpdatePanel1" runat="server" >
      <ContentTemplate>
    <asp:GridView ID="GridView1" CssClass="result_grid" runat="server" CellPadding="3" ForeColor="Black" 
        GridLines="Vertical" BackColor="White" BorderColor="#999999" 
           BorderStyle="Solid" BorderWidth="1px" AllowPaging="True" PageSize="15" 
            >
        <AlternatingRowStyle BackColor="#CCCCCC" />
        <FooterStyle BackColor="#CCCCCC" />
        <HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" />
        <PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
        <SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" />
        <SortedAscendingCellStyle BackColor="#F1F1F1" />
        <SortedAscendingHeaderStyle BackColor="#808080" />
        <SortedDescendingCellStyle BackColor="#CAC9C9" />
        <SortedDescendingHeaderStyle BackColor="#383838" />
    </asp:GridView>
    </ContentTemplate>
    <Triggers>
    <asp:AsyncPostBackTrigger ControlID="btnSearch" />
    <asp:AsyncPostBackTrigger ControlID="GridView1" EventName="PageIndexChanged" />
    <asp:AsyncPostBackTrigger ControlID="Gridview1" EventName="PageIndexChanging" />
    </Triggers>
     </asp:UpdatePanel>
    <br />
    <br />

    </div>

我没有使用SQLdatasource我使用的是数据集。。。谢谢..

GridView的

PageIndexChanged

/

PageIndexChanging

事件将以异步方式调用。尽管在引发这些事件时，如果希望整个

UpdatePanel

控件也刷新，您可以添加

您只需为GridView定义
OnPageIndexChanging
&
OnPageIndexChanged
事件。将标记中的这些设置为：

<asp:GridView ID="GridView1"
     OnPageIndexChanging="GridView1_PageIndexChanging"
     OnPageIndexChanged="GridView1_PageIndexChanged"
...>
</asp:GridView>

你是说gridview无法更改页面吗？thaks一直在寻找这个
<asp:GridView ID="GridView1"
     OnPageIndexChanging="GridView1_PageIndexChanging"
     OnPageIndexChanged="GridView1_PageIndexChanged"
...>
</asp:GridView>

protected void GridView1_PageIndexChanging(object sender,GridViewPageEventArgs e)
    {
        GridView1.PageIndex = e.NewPageIndex;
        // must call your Data filling function, else gridView will be empty
        BindGridviewDataWebloan(); 
    }
