I got Max's code, slightly edited, to build OK. Not yet tested. Thank you, Max.

As he notes, his code offers very basic features (page number, total pages, back, forward, and refresh).

I really don't want my mobile user scrolling through hundreds of entries or pressing the same button repeatedly when avoidable. A fuller Telerik implementation, similar to Telerik's Blazor Pager or WPF DataPager, would be very helpful; I only plan to use my code as a stopgap until better becomes available.

My edits to Max's:

Instead of fixed stylings per button, used Button Styles I had already defined in Resources.MauiStyles having no need for FontAwesome (some of which requires a paid subscription).

Named each button.

Using char.ConvertFromUtf32() in the code behind, replaced the use of FontAwesome text icons and the FontAwesome XAML reference by setting button texts from Unicode symbols :

Back: 0x21D0

Fwd: 0x21D2

Refresh: 0x27F3

In code behind, changed DelegateCommand to Command and eliminated any unnecessary uses of "this."

@Hanoch I've just posted the code which I used for you to resolve this issue welcome to use it.
