How to add behavior to ComboBox SelectionChanged event

[modula2019]

Hello all I have been able to get the ComboBox from Microsoft.UI.Xaml.Controls.ComboBox package working. However, I want to be able to use the interactivity behavior for the SelectionChanged event as explained here in this blog https://github.com/unoplatform/Uno.XamlBehaviors. The moment I added the packages for the behavior, the application stopped building. I am using net8.0 and MVUX `

`

Sample project added

UnoApp1.zip

Best regards

Hi @modula2019,
Just so it is easier for anyone searching for the same info, I will re-share here the same info I shared with you on Discord here. I noticed after my answer there that you opened a discussion here.

Similar concept to the WCT v7.1.2 details that I previously shared with you in terms of how to add the PackageReference and PackageVersion with the new single project structure. In attachment here UnoApp1-updated.zip, you will find your sample with the adjustments.

In Directory.Package.props:

<ItemGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows'">
    <PackageVersion Include="Microsoft.Xaml.Behaviors.WinUI.Managed" Version="2.0.9" />
</ItemGroup>
<ItemGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) != 'windows'">
    <PackageVersion Include="Uno.Microsoft.Xaml.Behaviors.WinUI.Managed" Version="2.4.2" />
</ItemGroup>

In UnoApp1.csproj:

  <ItemGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows'">
    <PackageReference Include="Microsoft.Xaml.Behaviors.WinUI.Managed" />
  </ItemGroup>
  <ItemGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) != 'windows'">
    <PackageReference Include="Uno.Microsoft.Xaml.Behaviors.WinUI.Managed" />
  </ItemGroup>

I also updated <Interactivity:Interacton.Behaviors> for the correct <Interactivity:Interaction.Behaviors> in your code 🙂

@jeromelaban I think that we would need to update the details for https://github.com/unoplatform/Uno.XamlBehaviors.
