PropertyGrid when default CollectionEditor is overridden data source doesn't change

[browneg]

I am trying to disable properties in my PropertyGrid depending on the state of one of the CheckBoxes. eg:

When ProgramMaufacturingData is checked the properties below are enabled when unchecked the remaining properties are disabled.

I am doing this using the IsEnabled property of the PropertyGridEditorPrimitiveTypeCollectionControl:

<PropGrid:EditorTemplateDefinition TargetProperties="ManufacturerNames,TestFacilityNames"> PropGrid:EditorTemplateDefinition.EditingTemplate <DataTemplate> <toolkit:PropertyGridEditorPrimitiveTypeCollectionControl IsEnabled="{Binding DataContext.CurrentTestSuite.ProgramManufacturingData,RelativeSource={RelativeSource AncestorType=PropGrid:PropertyGrid}}" ItemsSource="{Binding Value}" /> </DataTemplate> </PropGrid:EditorTemplateDefinition.EditingTemplate> </PropGrid:EditorTemplateDefinition>

This does the job. However, I am finding that when the editor is called no changes are made to the bound data ItemsSource. I also find the same behaviour with PropertyGridEditorCollectionControl.

The problem doesn't happen if I use the default Collection Editor. So, if I comment out the above XAML and just let the PropertyGrid decide the editor then the ItemsSource data does update with the changes. Great! .. but then I can't use the IsEnabled function.

What am I missing?

I've resolved the immediate problem by using the default editor but adding a Style to the PropertyGrid resources:
