        {
            STUDENT stud = new STUDENT();
            stud.NAME = txtName.Text;
            stud.PHONE = Convert.ToInt64(txtPhone.Text);
            mgr.AddEntity(stud);
            mgr.SaveChangesAsync();

Hi Denisk

This is how I am getting records on Datagrid

public ObservableCollection<STUDENT> Students { get; private set; }
             var query = _mgr.STUDENTs;
              query.ExecuteAsync(op => { op.Results.ForEach(Students.Add);}, null);

Like this I am showing details with Clicking on Data grid
private void StudentGrid_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            if (StudentGrid.SelectedItem == null)
            {
                return;
            }
            else
            {
              StudentSorders   aa = (StudentSorders)StudentGrid.SelectedItem;
                _id = aa.ID;
               txtName.Text = aa.NOME;
            }
        }
Here after diplaying record on txtbox i am doing add/delete/ update operation and this time
i need validation.

private void btnUpdate_Click(object sender, RoutedEventArgs e)
        {
                    STUDENT stud = Students.Where(t => t.ID == Convert.ToDecimal(_id)).Single();
                    stud.NAME = txtName.Text;
                    StudentGrid.ItemsSource = Students;
                    _mgr.SaveChangesAsync();
        }

Thanks
