| DiagramItemCollection |
The collection of diagram items.
|
DiagramItem objects must be added to the Items collection to be displayed in the DiagramControl.
Diagram shapes (DiagramShape) are positioned on the diagram canvas with the DiagramItem.Position property. You can specify a diagram shape’s position and size in the object’s constructor. For information on DiagramConnector positioning, see this class description.
The DevExpress.Diagram.Core.Native.DiagramExtensionsCore.Connectors extension method returns the collection of Connectors contained in the diagram. Using this method is more efficient than iterating through the Items collection.
The following code snippets (auto-collected from DevExpress Examples) contain references to the Items property.
Note
The algorithm used to collect these code examples remains a work in progress. Accordingly, the links and snippets below may produce inaccurate results. If you encounter an issue with code examples below, please use the feedback form on this page to report the issue.

foreach (var item in diagramControl1.Items) {
var shape = item as DiagramShapeEx;
