DataTriggerBehaviour: exception when using 0.6 for French locale?

[niels9001]

Hi all,

I'm using the following code to change the opacity of the selected item of a GridView.

<Core:DataTriggerBehavior Binding="{Binding ElementName=RoomsView, Path=SelectedItem.Id, Mode=OneWay}" Value="{Binding Id}" ComparisonCondition="NotEqual">
                                <Core:ChangePropertyAction TargetObject="{Binding ElementName=TitleTxt}" PropertyName="Opacity" Value="0,6" /> <!-- Needs to be a , else it will crash on French -->
                            </Core:DataTriggerBehavior>

Now this code runs fine. However, when I switch the language to French the app crashes. It can somehow not parse 0.6. When I enter 0,6 (mind the comma) it runs fine.

This is the exeption:

System.ArgumentException: 'Impossible d'attribuer une valeur de type String à la propriété Windows.UI.Xaml.PropertyPath de type Double. Seules des valeurs de type Double peuvent être attribuées à la propriété Windows.UI.Xaml.PropertyPath.'

Inner exception: FormatException: Input string was not in a correct format.`

Is there some parsing going wrong here wrt the point and the comma?

Regards, Niels

Hmm. That probably means somewhere a string is parsed without using invariant culture. Very peculiar no-one ever hit that before.

Issue confirmed, as one can see here!

For some weird reason, this is using CultureInfo.CurrentCulture instead of CultureInfo.InvariantCulture... notice that this is only if the data type is double, for int we actually use the correct invariant culture.

I've now pushed a fix, waiting for someone else to review & comment on it.

[LocalJoost]

Did review. No comment 😉

Yep, I found out when French users trying to start the new update.. oops :).

@PedroLamas @LocalJoost Thanks for the quick help, guys! Hopefully it gets merged and pushed to NuGet soon!

[pedrolamas]

This is now merged, but pushing a new NuGet package is out of my hands... @karann-msft or @mgoertz-msft any chance you can help with that?

[mgoertz-msft]

@PedroLamas Of course. Looking at the source history for the repo it looks like this is really the only functional change since the last release and it affects the managed SDK only. There have been some changes in the NuGet publishing process that we will need to adopt first but it will make it a lot easier and faster going forward.

@branh Could you please bump the version numbers to 2.0.1 and set up the publishing pipeline similar to the WPF Behaviors? Thank you!
