How to add new object DataContext ?
-
Im using the object DataContext to save some object to DB. I see that the object presistence is Ok - but after i stop the debug and i recompile it - i dont see the object anymore. The saving action that i did: dataContext.table.InsertOnSubmit( someObject); dataContext.SubmitChanges();

If they've been persisted, query them back.

I impliment the InsertCustomer method - the code :
void InsertCustomer(Customer instance) { this.ExecuteDynamicInsert( instance ); }And still nothing saved in the DB file.That's not what you said in the original post.

Why are you subclassing DataContext?

Sorry ... i did not said that dataContext is define in the code below public partial class dataContext : System.Data.Linq.DataContext { .... }
Yes, of course you are subclassing DataContext. I understood that. Would like to answer the question now?

I dont know the other way. I saw in all the code example that i need create subclassing Datacontext and with this subclassing to call the InsertAllOnSubmit and SubmitChanges method. Please tell me where i wrong.
And therein lies the problem, trying copy and paste code you don't understand.
