Child region navigation on a TabItem

[buruhazard]

Hi Prism Team!

So, I made it work. Same as on the Pluralsight course. I found the following:

My TabViewModel model have scoped region manager and IActiveAware. All tabs subscribeb to a event (IEventAggregator) , when this event fires there is a RegionManager.RequestNavigate("CildRegionOfTheTab", "SomeView") on TabViewModel , the SomeView depends on the parameter of the event. This navigation sets all the TabViewModel's IsActive to true.

Is that how it should be? I fixed the issue with a local variable that saves the current IsActive, and restore it after the navigation.

Constructor:
_ea = ea;
_toggleModeChangedEvent = _ea.GetEvent<ToggleModeChangedEvent>();
_toggleModeChangedEventToken = _toggleModeChangedEvent.Subscribe(OnToggleModeChangedEvent);


private void OnToggleModeChangedEvent(bool obj)
        {
            // Save IsActive state
            bool isActive = IsActive;

            if(obj == true)
            {
                RegionManager.RequestNavigate(RegionNames.GCodeTabContentRegion, nameof(GCodeEditorView));
            }
            else
            {
                RegionManager.RequestNavigate(RegionNames.GCodeTabContentRegion, nameof(GCodeProductionView));
            }

            // Restore IsActive state
            IsActive = isActive;
        }

Best regards,
