We are currently using the RadPropertyGrid control to display information for different types of Business Objects. We're also using the Command pattern to support undo / redo functionality for certain actions (adding a new Business Object, removing a Business Object, etc.).

What we would like to be able to do is somehow hook our RadPropertyGrid into our Undo/Redo Service. We have considered listening to the PropertyChanged event of the object that is currently being display through the RadPropertyGrid, but wanted to see if anyone else had tackled this problem before, or could point us in the correct direction.

Any help would be greatly appreciated.

Thanks,
Derrick

Hello Derrick,

Generally, handling PropertyChanged will be the way to go if you want to know when a certain property has been changed and to be able to save the previous value. Another possible way could be to rely on IEditableObject Interface and undo the changes for the whole object.

I noticed that in the WinForms version of the RadPropertyGrid there are two events: PropertyValueChanging and PropertyValueChanged.
Is there a reason that these two events are not fired in the WPF version of the Property Grid?

We'd really like to be able to subscribe to these events so that we can use them to handle our undo functionality.

Thanks,
Derrick

Hello Derrick,

 In WPF the popular pattern is MVVM (unlike WinForms) and you can prepare a special view-model where you can work directly with property setters.
