CollectionView Header and Footer not shown in Windows

[SimonORorke]

Description

In Windows, when trying to add any content inside a Header/Footer to a CollectionView, it is not being displayed.

This was previously reported in Issue 14557. That is now closed, fixed by Fix CollectionView not displaying header or footers. However, I still get the same problem. So this issue is a deliberate duplicate of closed Issue 14557, which I cannot reopen. Below, I've reference the same public reproduction repository as was provided for Issue 14557.

Steps to Reproduce

Create new project
Add CollectionView with a ItemsSource
Add a Header/Footer to the CollectionView

Is this a regression from previous behavior?

Not sure, did not test other versions

Last version that worked well

Unknown/Other

Affected platforms

Windows

Affected platform versions

windows10.0.22621.3233

Did you find any workaround?

Include in Platforms\Windows\App.xaml.cs constructor:
CollectionViewHandler.Mapper.AppendToMapping("HeaderAndFooterFix", (_, collectionView) => { collectionView.AddLogicalChild(collectionView.Header as Element); collectionView.AddLogicalChild(collectionView.Footer as Element); });

Verified on VS 17.10.0 Preview 2.0(8.0.7). This issue doesn't repro on Windows 11, Android 14.0-API34, iOS 17.2 and MacCatalyst with below Project:

Yes, the problem is fixed with Visual Studio Community 17.9.5.

This is not working for me when using HeaderTemplate / EmptyTemplate on Windows, which are required for things to work properly on iOS/Android with the latest 8.0.40 build.

I have the same problem.
Header and Footer are showing fine on Android/IOS.

<CollectionView ItemsSource="{Binding LicensePlates}"
                ItemTemplate="{x:StaticResource LicensePlateTemplate}"
                HeaderTemplate="{x:StaticResource LicenseHeaderCollectionViewTemplate}"
                Header="{Binding .}"
                >

• But on Windows it won't show when we use HeaderTemplate.

• I tried searching for the problem and found an old solution. Of course it failed. If you want you can try adding this code to App.xaml.cs (Shared) or Windows Platform:

#if WINDOWS
            CollectionViewHandler.Mapper.AppendToMapping("HeaderAndFooterFix", (_, collectionView) =>
            {
                collectionView.AddLogicalChild(collectionView.Header as Element);
                //collectionView.AddLogicalChild(collectionView.Footer as Element);
            });
#endif

#endif
