there is different ways: first solution is to use events and attach to the event from the other viewModel. here is an example: public FirstViewModel() { } public string Name { get { return name; } set { SetProperty( ref this .name, value); } } } in the second VM public SecondViewModel() { FirstViewMode.PropertyChanged += Current_PropertyChanged; } public string Name { get { return name; } set { SetProperty( ref this .name, value); } } private void Current_PropertyChanged( object sender, System.ComponentModel.PropertyChangedEventArgs e) { switch (e.PropertyName) { case "Name" : OnPropertyChanged( "Name" ); break ; } }

Hi, In order to achieve this, you'll have to make Has-A relationship with yourViewModel. Then bind MyOtherVMProperty.PropertyNeedsToBeBound class YourViewModel{ private OtherViewModel myVar; public OtherViewModel MyOtherVMProperty { get { return myVar; } set { myVar = value; } } }
