#Remarks
Note
The Preload
method allows you to preload lightweight theme resources only. Use the Preload
Use this method if the preloaded view is “lightweight” and you populate it with controls at runtime or based on a parameter.
The following code sample calls the MyControl.Populate() method and asynchronously preloads resources for the MyControl after the method is executed:
using DevExpress.Xpf.Core;
using System.Windows;
public partial class App : Application {
static App() {
CompatibilitySettings.UseLightweightThemes = true;
}
protected override async void OnStartup(StartupEventArgs e) {
base.OnStartup(e);
await ApplicationThemeHelper.PreloadAsync(() => new MyControl().Populate());
}
}
