How to pass dynamic data to WizardController ?

[acrolink]

e.g. when opening the MainWindow holding it?

I have solved the issue by adding a DATA property to the controller, see the commit at my forked repo. Maybe should be considered in future release?

Hi, You can get the controller instance and set whatever properties you want to the object. i.e.

var controller = _navigationService.GetController<MyController>();
controller.MyDataProperty = data;

If you want to do something when a controller is created, you can subscribe to the ControllerCreated event

MVVMCNavigationService.ControllerCreated += (controllerId)=> {
    var controller = MVVMCNavigationService.GetController(controllerId);
    if (controller is MyController)
    {
        controller.MyDataProperty = data;
    }
}

Does that help with your use case?

Another suggestion: When you're in the MainWindow code-behind, you have the Region control that's tied to the controller. You can get the controllerId directly from the region and set whatever data you need.

var region = MyRegion; // assuming the region's x:name in XAML is "MyRegion"
var controller = _navigationService.GetController(region.ControllerID) as My Controller;
controller.MyDataProperty = data;

I have tried this:

var controller = _navigationService.GetController<WizardController>();
controller.MyDataProperty = data;

But getting this error message:

Sequence contains no matching element

But getting this error message:

This works indeed, only if done inside the ContentRendered event.

Great! I'm closing this issue. Feel free to reopen this one or a new one if you're still having trouble.
