✅ How to debug data binding for a control on a MAUI content page

I'm trying to get a DevExpress

DataGrid

DataGrid

control working as the only content on a MAUI content page. I'm setting the

ItemSource

ItemSource

property in the page

Loaded

Loaded

event and so far all I can manage is to see that my breakpoint in that event handler is getting hit when I debug the app on my Android device. Test data is being loaded correctly here, into an

ObservableCollection

ObservableCollection

and the

CollectionChanged

CollectionChanged

and

PropertyChanged

PropertyChanged

events are being raised by my view model, but when the loaded event handler completes, the

DataGrid

DataGrid

only shows column headers and zero rows.

I was previously using a

CollectionView

CollectionView

control and that was populating properly. I thought it should be a relatively small and simple step to switch to another, similar control, based on my dim memoroes of working with data binding in WPF. It appears it's not at all so simple.

I'm hoping to find other events I can add handlers for and use to examine properties on the control, and maybe set properties to observe changes in the running control. I would also like to try any other means I can find of debugging a control using standard MAUI/XAML data binding setups, and I would greatly appreciate any advice and suggestions on this.
