Examples

Tip

For more info, design guidance, and code examples, see Layout.

The WinUI 3 Gallery and WinUI 2 Gallery apps include interactive examples of most WinUI 3 and WinUI 2 controls, features, and functionality.

If installed already, open them by clicking the following links: WinUI 3 Gallery or WinUI 2 Gallery.

If they are not installed, you can download the WinUI 3 Gallery and the WinUI 2 Gallery from the Microsoft Store.

You can also get the source code for both from GitHub (use the main branch for WinUI 3 and the winui2 branch for WinUI 2).

Remarks

You should not use the LayoutContext class directly. Instead, use it's derived classes, NonVirtualizingLayoutContext or VirtualizingLayoutContext.
