Hi Blanca,
Thanks for contacting Syncfusion support.
We are glad to inform you that we have achieved your requirement in simple sample. We suggest you to define the custom properties in a separate class and set the PropertyGrid’s SelectedObject as the customized property defined class and also no need to set the PropertyEditors Diagram property in order to achieve your requirement.
Code Example:
CommonProperties properties = new CommonProperties();
propertyGrid1.SelectedObject = properties;
We have attached a sample for your reference.
