sample request

Which version of the app?

WinUI 3 Gallery

Description

This proposal suggests adding an example to the WinUI3 Gallery showcasing the IsModal property of the OverlappedPresenter class. This property allows developers to create modal windows within the same application, improving the user experience for specific scenarios.

A lot of developers try to solve issues by turning off the Content.IsTapEnabled setting in another window, or by using the ContentDialog control as a substitute. However, these methods may not be the best practices and can come with several limitations:

• Using Content.IsTapEnabled: This can limit the app's interactivity.
• Using ContentDialog: This control is designed for simpler tasks and not to function like a window. It may lack the flexibility and customization options that a window provides.

Therefore, it would be beneficial to add an example to the WinUI 3 Gallery that showcases how to use the OverlappedPresenter.IsModal property in the windowing part. This could be a great feature to add, as it allows a window to behave as a modal dialog, blocking input to other windows, which can be useful in creating more interactive and user-friendly applications.
