gridview分页问题

Question

我使用gridview，其中当单击下一页时pagingsize为5，它返回空数据。但实际上它有12个datas.im，使用sql作为后端，asp.net c＃和数据r在运行时计算并显示。 即时通讯使用此代码

<asp:GridView ID="GridView_attendancereports"  BorderWidth="1px" BorderColor="#DBDBDA" runat="server" AutoGenerateColumns="False" CssClass="Grid" HeaderStyle-BackColor="#7E7E7C" Width="700px" AllowPaging="True" AllowSorting="True" OnPageIndexChanging="GridView_attendancereports_PageIndexChanging" PageSize="5"  >

Answer 1

你需要在页面索引更改事件中重新绑定，如

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    DataTable dt = GetAllCity();// you need to get here again data from database or from some other sources as you have, to populate your gridview properly
    GridView1.DataSource = dt.DefaultView;
    GridView1.DataBind();
}

Answer 2

尝试重新绑定到您的数据源。
