DevExpress WPF Property Grid

PropertyGridControl is a data-bound control that displays and edits the properties of an arbitrary object. Set SelectedObject to any INotifyPropertyChanged/POCO object, optionally describe which properties to show and how with PropertyDefinition / CollectionDefinition / CategoryDefinition, and the grid renders a correct editor per type, supports collection add/remove, multi-object editing, categories (flat / grouped / tabbed), and nested-object expansion.

This skill covers project setup, defining PropertyDefinition objects, editing collection properties via CollectionDefinition, grouping via property categories, and controlling expandability of complex/nested properties.

When to Use This Skill

Use this skill when you need to:

• Bind a PropertyGridControl to any CLR object and render an editor per property
• Choose which properties show — and assign custom editors per property/type via PropertyDefinition
• Let users add / edit / remove items in a collection property inline via CollectionDefinition
• Provide default values for new collection items (NewItemInitializer)
• Group properties under category rows or category tabs ([Category] attribute + ShowCategories)
• Make a nested object expandable (or block expansion) via [TypeConverter] / AllowExpanding
