Bind events to properties and vice-versa in WPF

I am rather new to bindings and WPF, but I've been able to do a few interesting things with bindings (interesting to me at least)

Does anyoine know if it's possible to bind an event (For example a SelectionChanged o Click event, etc) to a property (For example: IsChecked, IsEnabled, etc)?

I know I can bind properties with the Path property and all.

If you want to bind events to Commands you can do it through Attached Behavours. Have a look at this blog as to how to do that with MVVM Light. Binding to IsEnabled does not make much sense

An example they give is:

<Button>
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="Click" >
            <i:InvokeCommandAction Command="{Binding FooCommand}" />
        </i:EventTrigger>
    </i:Interaction.Triggers>

In ViewModel

public MyViewModel()
{
    //set it as a toggle for example
    FooCommand = new RelayCommand( () => IsChecked = !IsChecked );
 }    

public ICommand FooCommand { get; private set; }

public bool  IsChecked
{
   get { return _isChecked; }
   set { _isChecked = value;
        RaisePropertyChanged("IsChecked"); }
}
