Property Categories

Expanded Overview

The PropertyGrid control can divide the properties of the bound object into categories. Properties from the same category are displayed within an expandable group. To specify a category, decorate a property of the bound object with the Category attribute. The PropertyGrid control automatically generates category rows based on the category attribute values.

The following example demonstrates how to decorate properties of the bound object with the category attribute.

End-users can switch between categorized and flat display modes at runtime using the Tool Panel. To specify the default category display mode, use the PropertyGridControl.ShowCategories property. The image below demonstrates both display modes.

Expanded Using Category Definitions

Category definitions represent the category rows and specify their appearance within the property grid. Category definitions are represented by theCategoryDefinition objects that are stored within the PropertyGridControl.PropertyDefinitions collection.

The following example demonstrates the CategoryDefinition objects that specify the custom category headers.

The image below demonstrates the result.

Expanded Tabbed View

To display each category in a separate tab, set the PropertyGridControl.ShowCategories property to Tabbed.

The following example demonstrates how to use the CategoryDefinition objects to specify a glyph for each tab header.

Expanded Applying Mode

You can create different property definitions for each of the display modes. The PropertyDefinitionBase.ApplyingMode property specifies whether a property definition should be applied in the categorized or flat mode.

The example below demonstrates a property grid that is configured in the following way.

  • The ID property is visible in both the flat and categorized display modes.
  • The Email property is visible in the categorized mode only.
  • The Name property has different descriptions in each of the display modes.
