In this blog we will know how to save data to an xml file
and retrieve the data to a Gridview.Here we have to provide one value in the
Xml file manually as
Data.xml
<?xml version="1.0"
standalone="yes"?>
<studentdata>
<student>
<sid>s001</sid>
<sname>Raj</sname>
<saddress>Pune</saddress>
<smarks>100</smarks>
</student>
</studentdata>
