In our project we are using

-Entity Framework - Repository Pattern + Unit of Work Pattern together + We are using Devexpress controls.

The related part of the code for initializing our grid is:

UOW = new RepositoryObject.Core.UnitOfWork();
repXtraGridAddXtraEditor = new RepositoryObject.DesignLayer.XtraGridViewAddXtraEditorRep(UOW,   true);
XtraGridViewXtraGridEditorList = new   RepositoryObject.DesignLayer.XtraGridViewAddXtraEditorRep(UOW, true).Query(t => t.XtraGridViewId == XtraGridViewId).ToList();
BindingSource bSource = new BindingSource() { DataSource = XtraGridViewXtraGridEditorList};
grdXtraGridAddXtraEditor.DataSource = bSource;

When we delete a row from our grid

// Delete as entity
repXtraGridAddXtraEditor.Delete((BusinessObject.DesignLayer.XtraGridViewAddXtraGridEditor)gvwXtraGridAddXtraEditor.GetFocusedRow());
//reflect changes to DB
UOW.Db.SaveChanges();
// Delete from grid ( from screen)
gvwXtraGridAddXtraEditor.DeleteRow(gvwXtraGridAddXtraEditor.FocusedRowHandle);
//unsure pieces of codes  
bSource.EndEdit();
bSource.ResetBindings(false);

UNLESS we use the BOTH OF DELETES, the delete is not sychronized.

In other words, Grid and ENTITY FRAMEWORK are not aware of each other .

1- Is there something that I am missing ?
2- Is there a better alternative method ?

Thanks all
