✅ How to handle commands in TreeView?
According to the methodology by which I do this practical work, I need to visualize the territorial division of Kazakhstan using TreeView, using C# + WPF and the MVVM. What is the best way for me to make sure that I have 2 hierarchies (oblasts and cities), and that when I click on an object from the list, a command is triggered and displays information about this object to me (population, area, image, etc.)
