View and Update XML using C#

This is complete project

How will it works.
1) This code contain master page so just remove it if u don't need.
2) All the xml files will show in a Table  in page XmlFiles.aspx.
3) Select File that you want to open.after selection selected file will open in page 2.
4) System.Configuration.ConfigurationManager.AppSettings["configFiles"] contain folder path where xml files exist.


This page will show all xml files in a table.
