@joaopaulovw no problem.

Hola. It's been a long time since I last came here. I want to give Uno another go for our LOB app. My main issue was, and still is , that wen need a datagrid with grouping and subtotals per group. Any news on wct datagrid, syncfusion, telerik? It doesn't seem to have any traction really.

viewmodel.cs
Task MyMethodAsync() => Task.CompletedTask;

page.xaml:
Click="{x:Bind ViewModel.MyMethodAsync}"

page.g.cs
            case 7:
                        this.obj7 = target.As<Microsoft.UI.Xaml.Controls.Button>();
                        this.obj7Click = (global::System.Object p0, global::Microsoft.UI.Xaml.RoutedEventArgs p1) =>
                        {
                            this.dataRoot.ViewModel.MyMethodAsync(); // warning CS4014
                        };
                        (target.As<Microsoft.UI.Xaml.Controls.Button>()).Click += obj7Click;
                        break;

result: warning CS4014: Because this call is not awaited, execution of the current method continues before the call is completed. Consider applying the 'await' operator to the result of the call.

Anyone knows what's the appropiate thing to do in this case?

@akima15

I seem to have at least 3 choices:
1) Go back to using ICommand
2) Create void_MyMethod() => _MyMethodAsync() and binding to this method
3) Ignore warnings in generated file (i dont know how to target just the generated files tho)

Does Uno Platform support minimizing the app to tray rather than the taskbar?

Andrii Chebukin

@xperiandri

Only on WinUI

It is not recommended approach

What is your scenario?

@akima15 I know

Ping me tomorrow

nathanAjacobs

@nathanAjacobs

@xperiandri, I know plenty of apps that are configured this way. On my windows machine I have Spotify, MSI Afterburner, Logitech G Hub, and Mouse Without Borders which all use this approach.

The app I'm developing will not require a GUI 99% of the time. Only when configuration is needed, so I don't want it hogging up space as a window in the taskbar.

The main functionality of the app checks to see if a user defined keyboard combination is being held down, then communicates that to other connected clients which then simulate a completely different (or same) user defined keyboard combination being held down.

I'm developing the app to work with Windows first (I'm most familiar with it and have all the keyboard stuff already working), but would like to add Mac support later and possibly Linux support.

Since most of the keyboard functionality already requires low level OS specific code, I'm trying to minimize having to redo the UI for each platform as well.

Also I don't want to use WinUI because I don't want to limit my user base just to Windows 10 on Windows platforms.

Andrii Chebukin

@xperiandri

Use WinUI Uno template

There are no other modern options

nathanAjacobs

@nathanAjacobs

Use WinUI Uno template

Well it looks like WinUI can be used on Windows 7 with Uno. But does Uno plan to add support for Menu bar icon on mac and system tray for linux?

Andrii Chebukin

@xperiandri

It is not related to Uno

Use it per platform

Platform-specific code

nathanAjacobs

@nathanAjacobs

Gotcha, yeah that makes sense in a way. But at the same time, it would be nice for a cross platform UI framework to have some helper functionality for it on the corresponding platforms, rather than have each individual project implement it themselves. At the end of the day it is still UI functionality. But that's just my opinion.

Plus now that .NET is cross platform, you are gonna have people that don't know a lot about platform specific stuff for every platform (and shouldn't need to know).

Andrii Chebukin

@xperiandri

But the tray icon is totally platform-specific thing

akima15

@akima15

I'm side loading my WINUI3 app into another machine and when I run it its telling me to install the ".NET5 Desktop Runtime" which makes sense.

Now I'm planning to upload it to the Microsoft Store and I'm wondering if the user will have to manually install it as well or if the msix installer will take care of this dependency

Piotr Karocki

@pkar70

Tray icon is totally platform-specific, yes. But in some way exist in (almost) all platforms, so it could be implemented in multiplatform framework. \

Ok so my app got approved and the user will have to manually install it :(

Andrii Chebukin

@xperiandri

Maybe you can mark it as a dependency somehow...

@akima15

Maybe you can mark it as a dependency somehow...

I wish I knew how ( if its even possible)

I've decided to publish it as a single file but since WinUI doesnt support IL trimming yet the size is 100mb T_T

The error send the users to https://dotnet.microsoft.com/download/dotnet/5.0/runtime and some users may not even know which architecture to choose

I am trying to use something like IObservable<IEnumerable<MyCustomClass>> to be returned from a method making HttpCall but it doesn't work on WASM. I do have PlatformEnlightenmentProvider.Current.EnableWasm(); but still nothing happens

Hi all, is there a propertygrid control available for uno platform?
I looked at the WCT without success.

@janniksam

Is there any way to do things like this in Uno:
<DataTemplate x:DataType="viewModels:SettingsDetailViewModel">

<views:SettingsDetailView/>
</DataTemplate>

Couldnt get it to work. It always shows the viewmodel string.
