TasksInTabs example

[rtburke]

Hello,

I am new to MVC# and am trying to extend the TasksInTabs example. I am struggling to understand how the Application layer (TabTask1 for example) can communicate with the view (for example to change the text on the label).

I realise this is probably a very simple question but any help is appreciated.

Thanks

Hi,

In MVC/MVP patterns it's usually controllers/presenters who initiate changes in UI (in other words they control their views).

So I recommend that your Task sends a message to the controller which then would access its view. Here's an example how a task can access a controller:

this.Navigator.GetController(TabTask1.View2);

In particular you can access the current view:

this.Navigator.GetController(this.CurrViewName);

Make sure to initialize the view before accessing it. If the view hasn't been displayed or created yet, accessing it may result in an exception.

Kind Regards,

Hi Oleg,

Thanks for your prompt response. I understood the basic principle just not how to implement it!
