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.

How can I do this in code?

Thanks

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));

    Note for new visitors : This will not apply for regular Window controls. Mainly deals with Page, Frame, NavigationWindow. Read more in MSDN about how it works. http://msdn.microsoft.com/en-us/library/ms750478(v=vs.110).aspx – Sai Jul 31 '14 at 19:42

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.
