WPF DataBinding

Hi,

I just started exploring WPF Data Binding. Though I know to implement a simple data binding, but I want to understand what actually the INotifyPropertyChanged’s event handler - **PropertyChangedEventHandler **code does.


protected void OnPropertyChanged(String name)
{
       PropertyChangedEventHandler handler = PropertyChanged;

       [COLOR=Red]if (handler != null)
       {
            handler(this, new PropertyChangedEventArgs(name));
       }[/COLOR]
}

I want to know more what happens in the [COLOR=Red]red[/COLOR] text in the above code

I would be happy if anyone could explain me :slight_smile:

Thanks
