If my understanding of the internal workings of this line is correct:
public int MyInt { get; set; }
Then it behind the scenes does this:
I have created a custom Property class to do common operations like that. I haven't used it thoroughly yet though, but it could be used in this scenario.
Code can be found here: http://pastebin.com/RWTWNNCU
You could use it as follows:
readonly Property _myInt = new Property();
public int MyInt
{
get { return _myInt.GetValue(); }
set { _myInt.SetValue( value, SetterCallbackOption.OnNewValue, SetDirty ); }
}
private void SetDirty( int oldValue, int newValue )
{
IsDirty = true;
}
The Property class handles only calling the passed delegate when a new value is passed thanks to the SetterCallbackOption parameter. This is default so it can be dropped.
UPDATE:
This won't work apparently when you need to support multiple types (besides int), because the delegate won't match then. You could ofcourse always adjust the code to suit your needs.
