Using a style that uses the ResourceExtensions works only for the first element using it

[ArchieCoder]

Current behavior

Expected behavior

Same blue background for both buttons

How to reproduce it (as minimally and precisely as possible)

UnoApp1.zip

The only difference is I don't use BasedOn in my Style

@ArchieCoder if you add the BasedOn="{StaticResource DefaultButtonStyle}" then it should At least for the net8.0-desktop target, I will try with windows as well

[ArchieCoder]

Adding BasedOn="{StaticResource DefaultButtonStyle}" works for net8.0, but it does not work for WinUI.

this can be repro'd with:

var rd = new ResourceDictionary();
Border1.Resources = rd;
Border2.Resources = rd;

which is exactly what we are doing here.

@Xiaoy312 Thanks for the fast follow-up. Is this fix going to be in the next official release 5.3 only?

I don't know mergify. I see backport, but I'm not sure what it means.

[Xiaoy312]

I will let @agneszitte answer you.

[kazo0]

@ArchieCoder yep this will be in the next stable packages of Toolkit that will be part of the overall Uno 5.3 release

[ArchieCoder]

@Xiaoy312 I cannot repro the issue with the original app in this issue, but with my app, the bug still reside.

Here is a stripped-down version of my app.

@Xiaoy312 can you take a look at the new sample that @ArchieCoder provided, please (that uses Uno.Sdk 5.3.31 that normally includes the fixes for your previous PR #1190). Thanks in advance.

@Kunal22shah I will let you take a look as @Xiaoy312 is busy with other tasks please

Thanks @ArchieCoder for providing the zip file. I tested it with the latest 5.3.99 Uno SDK and it seem to work as expected, can you please confirm :

[ArchieCoder]

@Kunal22shah Did you try with Skia Desktop? With 5.3.99 and 5.4.0-dev.220, in Skia the buttons are gray not blue.

[Kunal22shah]

@ArchieCoder i ran the desktop WSL, it good for 5.3.99:

[ArchieCoder]

@Kunal22shah I added more style files from my project and I'm able to repro the issue.

Here is the new sample app: App1Updated.zip

Thank you a lot @ArchieCoder for the sample, @Kunal22shah will be able to investigate.

[Kunal22shah]

@ArchieCoder Thanks again, can you double check the app you shared, I don't see the buttons on WSL now:

vs desktop:

[ArchieCoder]

@Kunal22shah In WSL, I do not see the buttons as well. If you remove "Style="{StaticResource ActionButtonStyle}", you will see the buttons. The bug seems then worse in Linux. This is just a page with 2 buttons.

[Kunal22shah]

@ArchieCoder So upon investigation, it seems like its a uno bug and i have created this issue for the samehttps://github.com/unoplatform/uno/issues/18132. For now i would suggest the follow workaround to you:

For WinAppSDK : using latest toolkit version will fix it - <UnoToolkitVersion>6.2.0-dev.41</UnoToolkitVersion>
For WSL : you will need to add BasedOn="{StaticResource DefaultButtonStyle}" to the button style in the Page resources on the MainPage.

[ArchieCoder]

@Kunal22shah for the time being I will use the old style (that's the best workaround), but let me know when the bug will be resolved and I will test it. Thanks.

Since the original issue of the first element being the only one having the resources overridden I will close this issue. The other issue that was discovered is being tracked by: unoplatform/uno#18132

This one is a symptom of Uno's Generic.xaml have a different style than WinUI's Generic.xaml

Uno's generic.xaml button style: https://github.com/unoplatform/uno/blob/4dabe7d629771d24e312a9da948f24241387b167/src/Uno.UI/UI/Xaml/Style/Generic/Generic.xaml#L2898

WinUI's generic.xaml button style: https://github.com/microsoft/microsoft-ui-xaml/blob/69097129a853c65a16447aade4c82576d4724b1a/src/dxaml/xcp/dxaml/themes/generic.xaml#L5984

You can see that the WinUI default implicit Button style is using the ButtonBackground resource but the one in Uno is not
