Question

我正在尝试搜索，我的网格显示了20条记录的结果。

如果我已应用allow paging true且页面大小为20

然后点击Grid中的第二页，我的整个网格正在刷新，再次以第一页显示整个网格。

如果记录为20且页面大小为10，我如何查看最近10条记录，从11到20

网格的客户端代码

<div id="divApplication" runat="server">
    <asp:GridView ID="gvApplication"
        runat="server"
        AutoGenerateColumns="false"
        AllowPaging="true"
        AllowSorting="True"
        AlternatingRowStyle-CssClass="alt"
        PagerStyle-CssClass="pgr"
        OnPageIndexChanging="OnPageIndexChanging"
        CssClass="table table-bordered table-striped"
        PageSize="10" Width="50%">

        <Columns>
            <asp:TemplateField HeaderText='Application' HeaderStyle-VerticalAlign="Middle">
                <HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" CssClass="chkbox" />
                <ItemTemplate>
                    <asp:Label ID="lblFirstName" runat="server"
                        att='<%#DataBinder.Eval(Container.DataItem,"ID")%>' Text='<%# SetLinkCodeApplication(Convert.ToInt64(DataBinder.Eval(Container.DataItem,"ID")),DataBinder.Eval(Container.DataItem,"Application").ToString()) %>'></asp:Label>
                </ItemTemplate>
                <ItemStyle Width="3%" HorizontalAlign="left" />
            </asp:TemplateField>
        </Columns>

    </asp:GridView>
</div>

在C＃上绑定我的网格服务器端代码

public void fncfillApplication()
{
    try
    {
        DataSet ds = new DataSet();
        ds.ReadXml(Server.MapPath("Application.xml"));
        if (ds.Tables[0].Rows.Count != 0)
        {
            gvApplication.DataSource = ds;
            gvApplication.DataBind();
        }
    }
    catch (Exception ex)
    {
        ex.Message.ToString();
    }
}

protected void OnPageIndexChanging(object sender, GridViewPageEventArgs e)
{
    gvApplication.PageIndex = e.NewPageIndex;
    this.fncfillApplication();
}

用于在编辑模式下绑定数据的Setlinkcode

public string SetLinkCodeApplication(Int64 sId, string sName)
{
    string functionReturnValue = null;
    try
    {
        functionReturnValue = "<a href=javascript:fncopenEditPopUpApplication(" + sId + ")>" + sName.Trim() + "</a>";
        //return functionReturnValue;
    }
    catch (Exception ex)
    {
        throw;
    }
    return functionReturnValue;
}

我正在使用Xml Datasource来绑定数据

Answer 1

我认为你应该使用

  XDocument document = XDocument.Load(@"c:\users\administrator\documents\visual studio 2010\Projects\LINQtoXMLSelectApp\LINQtoXMLSelectApp\Employee.xml");
        var query = from r in document.Descendants("Employee") where (int)r.Element("Age") > 27 select new
        {
            FirstName = r.Element("FirstName").Value, Age = r.Element("Age").Value };
        GridView1.DataSource = query;
        GridView1.DataBind();

你的问题与我无关。它工作正常。我使用以下XML文件绑定到gridview。代码和HTML是一样的。

    <?xml version="1.0" encoding="utf-8" ?>

  <Customerinfo>  
    <Name>Vithal Wadje</Name>  
    <city>Mumbai</city>  
    <Address>Sion, Mumbai</Address>  
 </Customerinfo>  
  <Customerinfo>  
    <Name>D Sudhir Wadje</Name>  
    <city>Latur</city>
