DevExpress WPF Loading Indicators

Three different controls for "show the user that something is happening" — but they're not interchangeable. SplashScreenManager is a window-level splash screen for app startup or long operations (runs on a separate UI thread, immune to main-thread freezes). LoadingDecorator is a content container that wraps any UI and shows an indicator while the content loads (configurable owner-lock). WaitIndicator is a simple panel shown inside a window (runs on the main UI thread). All three live in DevExpress.Xpf.Core.

The older DXSplashScreen API is legacy. New apps should use SplashScreenManager instead.

When to Use This Skill

Use this skill when you need to:

• Show a splash screen at application startup
• Show a loading indicator over a region while it's fetching data
• Show a quick spinner while a button-triggered operation runs
• Decide between SplashScreenManager / LoadingDecorator / WaitIndicator
• Migrate from the legacy DXSplashScreen to SplashScreenManager
