Hello mobilewares, thank you for opening an issue with us!
I have automatically added a "needs triage" label to help get things started. Our team will analyze and investigate the issue, and escalate it to the relevant team if possible. Other community members may also look into the issue and provide feedback 🙌
@mobilewares this repo is about XAML Islands. You're calling out a WPF app, but then saying you're using WinUI 3 those are mutually exclusive things.
Can you clarify your scenario?
FYI @azchohfi as I suspect it's just a pure WinUI 3 app?
Looks like it.
This issue has been marked as "needs attention 👋" due to no activity for 15 days. Please triage the issue so the fix can be established.
@mobilewares still assuming you mean WinUI 3 and not WPF, they're different technologies. If you have a small repro with just ItemsRepeater and UniformGridLayout, these aren't toolkit components. Probably best to file an issue on the WinUI repo here: https://aka.ms/winuigithub
Describe the bug
WPF App crashes when using ItemsRepeater that has a UniformGridLayout Layout & number of items is being vertically scrolled by more than 2-3(?) screens worth (not 100% clear on exact quantity of items or pages that causes this). If number of items only use <1-2 pages (minimal vertical scrolling) then App works without crashing. ItemsRepeater is using DataTemplate with some binding (CommunityToolkit.MVVM).
Note - if not using the UniformGridLayout (just single column of vertical scrolling items within ItemsRepeater/ScrollViewer host) then this problem does not happen - seems to be when the UniformGridLayout is used only.
