GridView分页问题，请大虾帮忙

Question

我的GridView代码
<div id="div-datagrid" style="width: 98%; height: 380px">
                                            <asp:UpdatePanel ID="UpdatePanel1" runat="server">
                                                <ContentTemplate>
                                                    <asp:GridView ID="GridViewTraces" runat="server" CssClass="gen-table" AutoGenerateColumns="False"
                                                        DataKeyNames="AutoID" DataSourceID="ObjectDataSourceTraces" Width="100%" PagerStyle-HorizontalAlign="right"
                                                        BorderWidth="0px" GridLines="None" OnSelectedIndexChanged="GridView1_SelectedIndexChanged"
                                                        AllowPaging="true" PageSize="500" EmptyDataText="There are no data here now!"
                                                        OnRowDataBound="traceData_RowDataBound" OnPageIndexChanging="GridViewTraces_PageIndexChanging">
                                                        <RowStyle CssClass="gen-row" />
                                                        <HeaderStyle CssClass="gen-header" />
                                                        <PagerStyle HorizontalAlign="Right" />
                                                        <EmptyDataRowStyle ForeColor="Red" />
                                                        <Columns>
                                                            <asp:CommandField ShowSelectButton="True" />
                                                            <asp:BoundField DataField="SIMID" HeaderText="SIMID" SortExpression="SIMID" />
                                                            <asp:BoundField DataField="Lang" HeaderText="Lang" SortExpression="Lang" />
                                                            <asp:BoundField DataField="Lat" HeaderText="Lat" SortExpression="Lat" />
                                                            <asp:BoundField DataField="ServerTime" HeaderText="Time (GMT)" SortExpression="ServerTime" />
                                                            <asp:BoundField DataField="TrackerTime" HeaderText="Time by Tracker" />
                                                            <asp:BoundField DataField="Speed" HeaderText="Speed" />
                                                            <asp:BoundField DataField="MovingDirect" HeaderText="Direction" />
                                                        </Columns>
                                                        <PagerSettings Position="Bottom" />
                                                    </asp:GridView>
                                                </ContentTemplate>
                                            </asp:UpdatePanel>
                                        </div>
<asp:ObjectDataSource ID="ObjectDataSourceTraces" runat="server" OldValuesParameterFormatString="original_{0}"
                                            SelectMethod="BLL_Trace_User_GetDataByCondition" TypeName="TZTrace.BLL.TraceBLL">
                                            <SelectParameters>
                                                <asp:Parameter DefaultValue="" Name="SIMID" Type="String" />
                                                <asp:Parameter Name="From" Type="String" />
                                                <asp:Parameter Name="To" Type="String" />
                                                <asp:Parameter Name="TimeZone" Type="String" DefaultValue="0" />
                                            </SelectParameters>
                                        </asp:ObjectDataSource>后台：
 protected void GridViewTraces_PageIndexChanging(object sender, GridViewPageEventArgs e)
        {
            this.GridViewTraces.PageIndex = e.NewPageIndex;
            GridViewTraces.DataBind();
        }
为什么我的分页有数据，但是单击第二页就显示没有数据了？？？

Answer 1

this.GridViewTraces.PageIndex = e.NewPageIndex; 
            GridViewTraces.DataBind(); 第二行数据重新绑定的方法有问题吧~

Answer 2

LOAD方法是怎样写的？？if(!ISpostPack){...}??

Answer 3

  用PagedDataSource实现分页吧！

Answer 4

http://www.cnblogs.com/s021368/articles/1322180.html这 里有一个简单的例子。看一下。

Answer 5

protected void GridViewTraces_PageIndexChanging(object sender, GridViewPageEventArgs e) 
        { 
            this.GridViewTraces.PageIndex = e.NewPageIndex; 
            //GridViewTraces.DataBind(); 
            //这里写BindGrid();你绑定gridview的方法
        } 

Answer 6

protected void GridViewTraces_PageIndexChanging(object sender, GridViewPageEventArgs e) 
        { 
            this.GridViewTraces.PageIndex = e.NewPageIndex; 
            GridViewTraces.DataSource = 数据源;
            GridViewTraces.DataBind(); 
        } 

Answer 7

给你最简单的分页代码
    protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        GridView1.PageIndex = e.NewPageIndex;
        GridView1.DataBind();
    }
只是绑定数据的时候在page_load中绑定就行.呵呵

Answer 8

里面在添加你自己写绑定GridViewTraces的方法例如：
protected void GridViewTraces_PageIndexChanging(object sender, GridViewPageEventArgs e) 
        { 
            this.GridViewTraces.PageIndex = e.NewPageIndex; 
            GridViewTraces_Bind（）；
        } 
GridViewTraces_Bind（）；//自定义让数据源绑定GridViewTraces的方法

Answer 9

我是用objecdatasource使用的是假分页
