Description John Hardman 2016-05-13 13:49:16 UTC
When using the keyboard to navigate around interactive controls on Windows (both WinRT 8.1 and UWP), the order that the controls are focused in (the tab order in Windows parlance) does not seem to follow any particular pattern.

It is not the order that controls appear in the UI hierarchy following either a depth first or breadth first traversal.
It is not the order that controls are created.
It is not left->right, top->down
It is not top->down, left->right

The result is that developers using Xamarin Forms, without creating custom layouts etc, have no predictability over what tab order will be followed at run time. This means that implementing accessibility is an issue.

Either an int property needs to be added to all interactive controls, that can be used to identify the order to use, or some predictability about the traversal order based on the UI hierarchy needs to be implemented.
