Then Add an xml by right clicking on solution--AddNewItem--select XML FIle--Name it as UserDetails.xml Inside the UserDetails.xml file add some user details tags and markups as shown below

In the aspx designer page add the below code to add a gridview

Now lets create the code behind programming to bind gridview to an xml file This namespaces needs to be added to code behind .cs file

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

        BindGridToXML();
      }
 }
private void BindGridToXML()
{
        using (DataSet ds = new DataSet())
        {
                ds.ReadXml(Server.MapPath("~/UserDetails.xml"));
                gvUserDetails.DataSource = ds;
                gvUserDetails.DataBind();
        }
}

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