Question

I am using linq to sql , and I return a queryable result from linq to sql :

var qry = from p in table select p;

Then I use this to bind to a xtragrid:

GridControl.DataSource = qry;

Then If I edit the records in xtraGrid, I just need to call
dataContext.submitChanges() to submit the changes back to database.

My question is :

Am I possible to just add new records into the qry result, and after that I only need to
call dataContext.submitChanges(), then linq can create new records on database automatically ?

Is that possible ?
Can someone point me the right direction ?
Thanks in advance !

Shot answer would be no. You need to call the Add method on the table property on your context.

Something like this:

var qry = from p in myDataContext.Table select p;

GridControl.DataSource = qry;

myDataContext.Table.Add(newRecord); // This is how to add new recrod

dataContext.submitChanges();
