[BUG]: Set Default Item for Nav Control

[sperry1625]

Describe the bug
Cannot select a default item for a Nav control.

To Reproduce
Steps to reproduce the behavior:

1. Add Nav control to screen
2. Create variable to use for SelectedKey property (ex. ctxSelKey)
3. Set Nav control SelectedKey property to variable, ctxSelKey
4. Set variable, ctxSelKey, to default key value

Expected behavior
With SelectedKey variable set to a default key, when Nav is shown the Item with the Key value = to the SelectedKey value will be selected.
If this is not how this is supposed to work, please provide an example showing how to set the default selection in a Nav control.

Screenshots
N/A

Additional context
I tried creating an InputEvent for SetFocus, SetFocusOnRowSetSelection and SetSelection. The documentation only shows that the Nav Control supports the SetFocus InputEvent. None of these worked.

I was able to figure out the issue. The problem with the Nav control is the ItemKey must be Text. It cannot be numeric. I would still classify this as a bug because keys are usually numeric for performance reasons.

Is this working by design?

Thanks for following up @sperry1625, we'll update documentation to make this clear. It is by design, the component looks for a specific data type, however the platform doesn't seem to give a good error message that lets you know it's not working. I'll log this as internal feedback as well so the team is awar.
