</Employee>

And here is my code behind

 XDocument doc = XDocument.Load(Server.MapPath(@"~/User.xml"));
            doc.Elements("User")
           .Elements("ID")
           .Where(l => l.Value == textbox1.text)
           .Select(x => x.Parent)
           .Remove();    

i want to remove the <user> node whose <id> is entered in textbox
but its not working.
Can you help me?

Answer 1

Add doc.Root property or doc.Descendants("User") to return filtered collection of the descendant elements :

1.

doc.Root.Elements("User")
           .Elements("ID")
           .Where(l => l.Value == textbox1.text)
           .Select(x => x.Parent)
           .Remove();

2.

 doc.Root.Elements("User")
            .Where(p => p.Element("ID").Value == textbox1.text)
            .Remove();
 doc.Save(Server.MapPath(@"~/User.xml"));
