Hi Bhargavi you can use following code for retrieving data from xml and displaying it on GridView:
At first add
System.xml
namespace.
XmlTextReader xtr = new XmlTextReader(Server.MapPath("myXml.xml"));
DataSet ds = new DataSet();
ds.ReadXml(xtr);
xtr.Close();
if(ds.Tables.Count != 0)
{
gridview.DataSource = ds;
gridview.DataBind();
}
All the best.
