Modal dialog please Help

[jcarnalich]

Hello,
we are a company from software development. We have programs made in MFC/C++ with thousands of customers.
We want to migrate our products from MFC/C++ to WinUI 3.

The main problem is that we use many modal dialogs. Many times from a modal dialog opens another modal dialog, and another... (see screenshot):

I have two questions:

1° plans Windows to do this type of modal dialogs in the future?
2° Is it possible to make modal dialogs from other modal dialogs with the current version of winui ?

we have tried to do the following without success:

a) Contentdialog/Flyout. It's ok but you can't open another Contentdialog/Flyout from a Contentdialog/Flyout.
b) Do it manually with UIElement.GotFocus Event.
c) Windowing. AppWindowPresenterKind.CompactOverlay. It's ok but you can't open another Window (modal with CompactOverlay) from a Window.
d) WinUI Extensions : WinUIEx. (It's based also in Windowing) It's ok but you can't open another WinUIEx from one WinUIEx.
e) Do it manually with Canvas, ManipulationMode="TranslateX, TranslateY, TranslateInertia", Visibility.Collapsed/Visible, IsHitTestVisible?

Could you please help us?
Thanks in advance!
Best regards

A way is to use the Window class, as it is possible now to create multiple windows on the same thread
A test, with EnableWindow to disable/enable parent windows :

    [DllImport("User32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
    public static extern bool EnableWindow(IntPtr hWnd, bool bEnable);

Thank you very much! I have installed the latest version of SDK and your solution works now with windowing.

It is a possible solution, but two questions please :

1° are there WinUI-Elements that allow me to do modal dialogs inside a window?
2° does Microsoft plan to do modal dialogs?

I have done something similar to a modal dialog with Canvas und ContentControl (ManipulationStarted, ManipulationDelta, ManipulationCompleted, Tapped, PointerEntered, Visibility, IsHitTextVisible)
but it is not a clean and good solution. (see screenshot)

Best regards
