Hi,
 
If you already have an ObservableCollection of Employees, why are you requerying one at time again?
Also, you don't need to call SaveChagesAsync to each Employee.
 
Try this instead:
 
foreach (Employee emp in SelectedEmployees)//where 'SelectedEmployees' is a observablecollection of type 'Employee'
{
  emp.EmpName = "new name";
}
manager.SaveChangesAsync();
Silvio.

Hello friends,

My requirement is to update multiple records in Employee entity using IdeaBlade. I have tried following code snippet. But it is updating only one record in Employee entity. Can anyone help me please. Its urgent.

 foreach (Employee emp in SelectedEmployees)//where 'SelectedEmployees' is a observablecollection of type 'Employee'
                    {
                       var empQuery = mgr.Employees.AsScalarAsync().First(i => i.EmpID == emp.EmpID);
                       empQuery.Completed += (o, i) =>
                        {
                            Employee newEmp =  i.Result;
                            newEmp.EmpName = "new name";
                            newEmp.EntityAspect.AddToManager();
                            manager.SaveChangesAsync();
                       };
                  }
