How Do I refresh window in wpf?

I have a small project I am working on which is a window with 4 WPF tabs on it.

The first tab is where I do most of the work, but occasionally I need to move back to other tabs. One of these tabs has a DataGrid that is bound to a list that is affected by the main tab I stay on.

When I update something on the first tab, I need it to cause a refresh on the data in the Datagrid(usually just to update a value).

The only way it has been working is if I click on the header myself.

Is the list an ObservableCollection or properties implementing INotifyPropertyChanged?

Have you tried:

myDatagrid.Items.Refresh();

Maybe:

this.NavigationService.Refresh();

or

this.NavigationService.Navigate(new Uri("<EnterPage name here.xaml", UriKind.Relative));

I used this workaround, it's no perfect but works

MainWindow newWindow = new MainWindow();
Application.Current.MainWindow = newWindow;
newWindow.Show();
this.Close();

If you are working on an Object that you are displaying shared properties you could implement the INotifyPropertyChanged interface and refresh the DataGrid. If its a collection you could look at the ObservableCollection class.
