yes i  m using L2S

  dc is created as

private MusicClassesDataContext dc = new MusicClassesDataContext();

where  MusicClassesDataContext is the model.

If not wat s the correct method must be used

The method is

dc.SubmitChanges();

as stated at

http://msdn.microsoft.com/en-us/library/system.data.linq.datacontext_methods.aspx

not

Priya R

dc.SaveChanges();

You have to look to a L2S tutorial - such as links from
