Display the WPF WaitIndicator

This example shows the WaitIndicator control. The control's DeferedVisibility property is bound to the View Model's IsWaitIndicatorVisible property.

<dx:WaitIndicator DeferedVisibility="{Binding IsWaitIndicatorVisible}" Content="{Binding WaitIndicatorText}">
    <!-- ... -->
</dx:WaitIndicator>

The WaitIndicator works within the main application's UI thread. The UI freezes may affect the WaitIndicator animation.

To show an indicator while the main thread is locked, use the following components instead of a standalone WaitIndicator:

• SplashScreenManager (available in v20.1 and newer) - shows an indicator window in a separate thread;
• LoadingDecorator - automatically shows the splash screen when the content element is loaded;
• DXSplashScreen (obsolete; use in versions prior to v20.1) - shows an indicator window in a separate thread;

Files to Look At
