Items with Custom Content

Expanded Overview

Simple Shapes in a DiagramControl only display their content as an editable string. Use the DiagramContentItem class to add custom elements to diagram items. DiagramContentItem has the DiagramContentItem.ContentTemplate property, which can be used to place any elements into the item.

To register a DiagramContentItem in the toolbox, use the DiagramStencil.RegisterTool method with FactoryItemTool as a parameter:

After that, register the stencil using DiagramToolboxRegistrator.RegisterStencil.

Note

To properly deserialize a DiagramContentItem, it's necessary to set its DiagramItem.CustomStyleId property, which accepts a Style key applied to the item.

Use DiagramContentItem to represent data objects in diagrams generated from a data source, by specifying DiagramContentItem as the DiagramDataBindingBehaviorBase.ItemTemplate. See the example below.

Expanded Example

The following example shows how to create diagram items that display custom content.
