PopupV2 name in ShellNavigatedEventArgs object

[MichaelShapiro]

In my Shell app I keep track of navigation points: source and destination. I basically subscribed to the Navigated event in the Shell:

<Shell 
        Navigated="ShellHost_Navigated"   
...
/>

Then I read and do something with the ShellNavigatedEventArgs event argument properties:
Previous.Location.OriginalString and Current.Location.OriginalString.

So far so good and I always had location names that are predictable - based on how route is named in the xaml declaration or how route is registered with Routing service ( for instance Routing.RegisterRoute("nstackErrorPage", typeof(ErrorPage));)

Then I have a popup

<toolkit:Popup .....
some content
/>

public partial class PopupInfo : Popup
{
some properties 
}

Then I call the popup:

        IPopupResult<string> popupResult = await Shell.Current.CurrentPage.ShowPopupAsync<string>(
            view: popupInfo,
            options: new PopupOptions
            {
                CanBeDismissedByTappingOutsideOfPopup = false,
                Shape = null,
                Shadow = null
            });

It does trigger the actual shell navigation and the names I keep seeing are somehow auto generated. like these:

//shellSettings/D_FAULT_PopupPage55
//shellSettings/D_FAULT_PopupPage56
//shellSettings/D_FAULT_PopupPage57
//shellSettings/D_FAULT_PopupPage58
//shellSettings/D_FAULT_PopupPage59
....

You get the idea. It creates a new unique name each time I call that popup.

Is there any way to control the name of the popup in Shell navigation Location object? I really was hoping to get a predictable name and not guess solely based on if the "popup" is contained in the full location name. Any help or directions are greatly appreciated!

At present this is not controllable as you can see by the code here:

Maui/src/CommunityToolkit.Maui/Extensions/PopupExtensions.shared.cs

Line 172 in 2217d08

Routing.RegisterRoute(popupPageRoute, new PopupPageRouteFactory(popupPage));

Thank you. Wish it was different, but I understand.

[bijington]

Feel free to open a proposal and suggest how we could make it possible to customise and we can take a look

[MichaelShapiro]

@bijington do you think that #2767 , at least partially, addresses the issue I raised here?

[bijington]

It won't give you the name of the previous page although you will get access to that in .NET 10.0 if the MAUI PR gets merged. This will let you check whether your page was navigated to from a popup though does that help?

[MichaelShapiro]

certainly it'd help. Thank you!

I have similar problem. Let's say I am navigation to a page, AddEditControl.

public async void ApplyQueryAttributes(IDictionary<string, object> query)
{
   bool IsEditMode = false;
   if (query.Count > 0)
   {
      IsEditMode = true;
   }
}

... which is OK. The problem is I show popup in the AddEditControl and when the popup is closed, the Shell goes back to the AddEditControl, but this time with empty query. All data is lost if the user is in the edit mode.

Is there any way @bijington to prevent this "refreshing" or re-applying ApplyQueryAttributes from the page where the popup was called?
Thank you.

[bijington]

The way to workaround this would be to store whether you have already navigated with a bool and return early out of ApplyQueryAttributes

[rokmeglic71]

OK, I have done this. Thank you.
