How to change UpdateSourceTrigger behavior in editors?

Hi Craig,

If you own WPF Studio, you can download the default Styles from our web site. If you purchased PropertyGrid separately, then you can send a request to our support address and we can provide the appropriate files.

The default PropertyGrid property editors are located in the "PropertyGrid\Themes\PropertyGrid\PropertyEditors.xaml" file. I did notice that the property editors for the Editors for WPF product are not included in the XAML style download. So if you send a request, we can send these files also.

To answer your questions, yes the correct way would be to redefine the property editor DataTemplates and change the UpdateSourceTrigger manually. PropertyChanged generally produces too many updates to the underlying object. Typically, it's better to wait until the user has finished entering the "data" before pushing it back to the underlying object. But this really depends on your requirements.
