In order for the editor to function, it must deal with a single property of the EditingControl as specified by this property. If no EditingControlPropertyName is specified, the editor will look for a property named Value on the control. Failing that, the Text property will be used. If neither a Value nor a Text property are found, the editor will not be able to function properly.
The ControlContainerEditor needs to know when the specified property on the control is changed. To do this, it will attempt to hook an event on the specified control with a name that matches the property (i.e. ValueChanged or TextChanged). If no such event exists or is not fired when the property changes, the editor will be unable to write changes to the owner. In the rare case where this happens, it is recommend that the developer derive a class from ControlContainerEditor and override the EditorValue property and set this property any time the editor value changes.
