How to split XAML code?

Question

WPF

Is it possible to somehow split a large XAML code into several view files? I even saw it somewhere already, i.e. is done for each UserControl view. But most importantly, what will happen to the binding? Because if you specify the same ViewModel as the DataContext everywhere, then a new Instance will still be created for each view ... Is it possible to somehow intercept the parent instance of the DataContext?

Answer 1

The DataContext descends from above anyway, you don't need to do anything extra for this.

Answer 2

You can bind controls to the DataContext of the parent control. Google the ElementName parameter of the binding

Answer 3

use the ContentControl class in the xaml of the main window/control to which you bind your UserControls (eg mainViewModel.SelectedControl = new MyUserControl()). DataContext is thrown by itself, it needs to be set only at the main window/control
