[Feature] Enable Tab visibility toggle

[nielscup]

Is your feature request related to a problem? Please describe.
Binding UnderlinedTabItem visibility property results in the tabItem being hidden when false, but leaves an unused space visible.

Describe the solution you'd like
If I set an UnderlinedTabItem.Isvisible to false I would like the remaining tabitems to fill the space.

Describe alternatives you've considered
Add tabItems in code

Adding tabs in code doesn't work (so far): If I clear tabs and re-add them they are not connected to any view anymore.

[nielscup]

Reason: _tabs is not updated in OnChildRemoved.

So if I do TabViewHost.Children.Clear() and re-add my 3 tabs, there are 6 items in _tabs.

Did you find a workaround for this, I'm having the same problem. When removing tabitems in code, the remaining tabs don't fill the boxview.

there is no workaround, the implementation needs to be changed.
I will work on that during august

Well, I think I have a workaround that seems to work. I have used it to hide a tab for a case.
For every TabItem added in XAML to the TabHostView view, a columndefinition having Width = Star is also added to the Grid that TabHostView is based on.
So If you get the columndefinition for the item to hide, then set Width to zero. Also to be sure that the tab is not accidentally activated, set its IsEnabled = false.

I am actually working on this issue at this very moment :)
Soon you will have the choice between fixed tabs and scrollable tabs, and the IsVisible property will be fixed for any of the tab types.

fixed in v1.3.0
