In this article, I am going to teach you, how to populate grid view control using a XML File as Data Source.
For using Customer.xml as data source, please refer my article “Populating Data in XML and Grid”.
Procedure:-
- I have used WriteXml( ) and WriteXMLSchema( ) to write the data content to my XML File and to write the data content to my XSD File respectively.
- Server.MapPath( ) is used to get the exact location of the corresponding file.

PopulateDataInXML.aspx.cs
using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Data.Sql;
using System.Data.SqlClient;
public partial class _Default : System.Web.UI.Page
{
SqlConnection conn = new SqlConnection("Data Source=CTS;uid=sa;pwd=home;Initial Catalog=Northwind");
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
loadMyGridAndXML();
}
}
public void loadMyGridAndXML()
{
conn.Open();
SqlDataAdapter sda= new SqlDataAdapter("select * from customers",conn);
DataSet data = new DataSet();
sda.Fill(data, "customers");
data.WriteXml(Server.MapPath("Customers.xml"));
data.WriteXmlSchema(Server.MapPath("Customers.xsd")); GridView1.DataSource = data;
GridView1.DataBind();
conn.Close();
}
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
loadMyGridAndXML();
}
}
When you run the above PopulateDataInXML.aspx page, what you get is:-
1. GridView gets populated J
2. Customers.xml and Customers.xsd will be auto – coded since you use WriteXml() and WriteXmlSchema() functions.
Your XML Output Looks Like This:-
Customers.xml :-
<?xml version="1.0"standalone="yes"?>
