This is the base View Model abstract class which contains the most common MVVM functionality


This class inherits from ViewModel and provides additonal functionality for managing lists of data

SearchViewModel<T, T2>

This class inherits from ListViewModel<T,T2> and adds search and filtering functionality to the standard ListViewModel

SearchTreeViewModel<T, T2>

This class inherits from SearchViewModel<T, List<T>> and adds Tree Path preparation to the standard SearchViewModel

Using System.Mvvm

Basic ViewModel

All of the ViewModel base classess are in the System.Mvvm namespace. To create a basic ViewModel simple inherit from ViewModel.

using System.Mvvm;
public class MainViewModel : ViewModel

To create a notifiable property create a property with a backing field using the propfull snippet and add a call to NotifyPropertyChanged.

private int myVar;

public int MyProperty
    get { return myVar; }
    set { myVar = value;  NotifyPropertyChanged();}

NotifyPropertyChanged will automatically pickup the calling member, but you can also be explicit.

private int myVar;

public int MyProperty
    get { return myVar; }
    set { myVar = value; NotifyPropertyChanged(nameof(MyProperty)); }
