How to get the class object that is bound to the View?

Question

WPF

Good day!
While I was studying how to create an application using the MVVM pattern, a question arose. Actually the details:
Task:
Create a functionality for adding tasks to the diary.
That is, when I click on the "OK" button, the command attached to the button should transfer the object of the "Task" class to the "Tasks" sheet of the "PlansPageVM" class, which in turn is attached to the "PlansPage" View. But to do this, I need to pass the actual object of the "PlansPageVM" class as a parameter to the command, the question is: how to do this?

Answer 1

The functionality that is tied to the command that is on the "OK" button should be in the View Model, that is, already inside your PlansPageVM class

Answer 2

Send button? What a mess you are.
The button is attached to the command, and in the team, if necessary, create a task and already pass it where you need it

Answer 3

Your application architecture is built incorrectly, VMs should not know about each other at all, your tasks should be stored in one place, not in the VM at all, and the VM should read, add, edit the list of your tasks with the help of a service (third-party auxiliary class). And the service is already being implemented through IoC containers in the VM.
