LINQ Update w/SPROC does nothing

Hi there, totally stumped and been looking for answers all morning.  Tried this
multiple ways but no matter what I do, nothing happens at all:

1    DataClassesDataContext myDB = new DataClassesDataContext();
2                ArgentCounter argentcounter =
myDB.ArgentCounters.SingleOrDefault(i => i.id == 1);
3                argentcounter.Blunderer = txtName.Text;
4                argentcounter.Date_Recover = calPickDay.SelectedDate;
5                myDB.ArgentCounters.Attach(argentcounter, true);
6                myDB.SubmitChanges();


 

SPROC:

1    set ANSI_NULLS ON
2    set QUOTED_IDENTIFIER ON3    GO
4    ALTER PROCEDURE [dbo].[sp_UpdateArgentCounter]
5    	@id smallint,
6    	@Blunderer varchar(50),
7    	@Date datetime
8    AS
9    	SET NOCOUNT ON;
10   update dbo.ArgentCounter
11   set Blunderer= @Blunderer, 
12   	Date_Recover = @Date
13   where id = @id
   

 

Just trying to do a simple update where ID = 1.  I set the Update properties for
my table in the DataClasses file to my SPROC rather than runime, and I don't get
any errors, and nothing updates.  Any idea what's up?  'id' is a primary key but
not identity.  I've got this code in a button click event, if that makes any
difference.  I have no problem using other SPROCs for select statments, perhaps
there is a different format for the update? --Thanks

DataClassesDataContext myDB = new DataClassesDataContext();
2                ArgentCounter argentcounter =
myDB.ArgentCounters.SingleOrDefault(i => i.id == 1);
3                argentcounter.Blunderer = txtName.Text;
4                argentcounter.Date_Recover = calPickDay.SelectedDate;
5               // myDB.ArgentCounters.Attach(argentcounter, true); - remove
this line
6                myDB.SubmitChanges();

With or without that line, nothing happens at all.  There is no error or update
to the database.

did you fire Update event

Can you please define "fire update event"?  In my dataclasses page I
defined the sproc as the custom update, but I don't have any other code for
doing an update.  Is there code for specifically firing an update event?
