asp.net 将页面HTML化，通过Ajax请求返回到窗户端

Ajax请求的WebService方法：

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
[System.Web.Script.Services.ScriptService]
public class PagingService  : System.Web.Services.WebService {

    [WebMethod]
    public string GetPagingData(int page)
    {
        ViewManager<PagingData> viewManager = new ViewManager<PagingData>();
        var control = viewManager.LoadViewControl("~/PagingData.ascx");

        control.PageIndex = page;

        return viewManager.RenderView(control);
    }
}

public class ViewManager<T> where T : UserControl
{
    private Page m_pageHolder;

    public T LoadViewControl(string path)
    {
        this.m_pageHolder = new Page();
        return (T)this.m_pageHolder.LoadControl(path);
    }

    public string RenderView(T control)
    {
        StringWriter output = new StringWriter();

        this.m_pageHolder.Controls.Add(control);
        HttpContext.Current.Server.Execute(this.m_pageHolder, output, false);

        return output.ToString();
    }
}

PagingData.ascx控件

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="PagingData.ascx.cs" Inherits="PagingData" %>

<asp:Repeater runat="server" ID="Repeater1">
    <ItemTemplate>

PagingData.ascx.cs

public partial class PagingData : System.Web.UI.UserControl
