Create a property of custom user control using c# Winforms

In Wpf, first create a different class and create a for Notify property changed viewmodelbase class:

public abstract class ViewModelBase : INotifyPropertyChanged, IMVVMDockingProperties
    { 
protected void OnPropertyChanged(string propertyName)
        {
            PropertyChangedEventHandler handler = PropertyChanged;

            if (handler != null)
            {
                handler(this, new PropertyChangedEventArgs(propertyName));
            }
        }
}

then where you are implementing this property just add one more line of code:

private string _Text;
public string Text
    {
        set 
        {
            _Text= value;
        }
        get 
        {
            return _Text;
            **OnPropertyChanged("Text");**
        }
    }

also if you want to get notified on every character entered event add this to your binding:

Binding="{Binding Path=Text, **UpdateSourceTrigger=PropertyChanged**, Mode=TwoWay}"
