Equivalent to InvokeRequired in WPF

Question

Is there an equivalent to Form.InvokeRequired in WPF, e.g. Dispatcher.InvokeRequired?

Answer 1

If you're building a Windows Store app, the above example won't work. Here's an example that does work. Modify as needed, of course :)

/// 

/// Updates the UI after the albums have been retrieved. This prevents the annoying delay when receiving the albums list.
/// 
/// 
public void UpdateUiAfterAlbumsRetrieved(System.Collections.ObjectModel.ObservableCollection albums)
{
    if (!Dispatcher.HasThreadAccess)
    {
        Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
        {
            ddlAlbums.DataContext = albums;
            ddlAlbums.IsEnabled = true;
            tbxProgress.Text = String.Empty;
            ProgressBar.IsIndeterminate = false;
            ProgressBar.Visibility = Windows.UI.Xaml.Visibility.Collapsed;
        });
    }
    else
    {
        ddlAlbums.DataContext = albums;
        ddlAlbums.IsEnabled = true;
        tbxProgress.Text = String.Empty;
        ProgressBar.IsIndeterminate = false;
    }
}
