Property Value

Type	Description
Object	An object whose properties must be retrieved via the event.

Remarks

First, the PropertyGridControl.CustomPropertyDescriptors event fires to retrieve root properties for the selected object. The Source member will identify this selected object.

Then, when expanding a property that contains nested properties, the event fires again, to retrieve these nested properties. The Source member will identify the object representing the parent property.
