I want to do paging in repeater control in asp.net. I can do custom paging with repeater with ado.net. But with linq i never did it. I try it but its not work Here is the code for binding my repeater with xml using linq

var doc = XDocument.Load(Server.MapPath("~/Data/BlogContent.xml"));
        var result = doc.Descendants("post").Where(x => x.Element("id") != null).Select(x => new
        {
            id = x.Element("id").Value,
            title = x.Element("title").Value,
            Description = x.Element("Discription").Value,
            dt = x.Element("dt").Value,
            mnt = x.Element("mnt").Value,
            yr = x.Element("yr").Value,
            postdate=x.Element("PostDate").Value
        }).OrderByDescending(x => x.id).Take(5);


        Repeater1.DataSource = result;
        Repeater1.DataBind();
