title: How to update values in users table of Parse.com
body: <p>Guys I want to update the rows of users table in Parse.com. So, far I have used user.SignupinBackground method to update password and other fields(added by me other than username and password) but it throws an exception "Cannot sign up a user that has already signed up." </p>
  
  <p>Is there a way to update the data in the rows of users table of parse.</p>
  
  <p>I have already visited <a href="http://parse.com/docs/dotnet/api/html/Methods_T_Parse_ParseUser.htm" rel="nofollow">this link</a> but i didn't found any method for updating the data in the rows of the current user.</p>
