How to update only a property in an observable collection from thread other than dispatcher thread in WPF MVVM?

Question

I am having a class named Employee. I need to update only the property Status from thread other than current dispatcher thread:

Answer 1

There is a big problem in your code. First, the ObservableCollection is already a collection that notifies on change, so you not need reinitialize it, just call Clear and Add/Insert.

Second, the Employee class should be ViewModelBase:

class Employee: ViewModelBase
{
   private string _status;

   public string Name { get; set; }
   public string Status
   {
     get
     {
        return _status;
     }
     private set
     {
        _status=value;
       RaisePropertyChanged("Status");
     }
   }
}

This should allow you to change DailyEmployees[0].Status="NewStatus";

LE: In case you have problems changing data from another thread, check this link: Using BindingOperations.EnableCollectionSynchronization

LLE: I used the ViewModelBase class for the Employee, because it was already used in the code sample. A raw answer would have mean implementing the class Employee: INotifyPropertyChanged and implementing the required method.
