ToolboxService.CreateItemContainer Method (IDataObject)
Creates a new toolbox item container from a saved data object.
Assembly: System.Drawing.Design (in System.Drawing.Design.dll)
The CreateItemContainer method gives you the opportunity to provide a derived version of a ToolboxItemContainer. By default, the ToolboxService class does not support linked items, so it returns null for link parameters that are not null. To provide link support, you should override this method to create a derived ToolboxItemContainer that is capable of handling links.
The data object passed in should contain data obtained from a prior call to the ToolboxItemContainer.ToolboxData property on a toolbox item container.Notes to Implementers
A linked toolbox item is one whose existence is tied to the storage of a particular designer host. So, in a typical project system, a designer host is associated with a particular file. A toolbox item linked to a designer host would automatically be deleted from the toolbox when the designer host’s source file is deleted or removed from the project.
Linked toolbox items make possible scenarios such as disabling the ASP.NET toolbox items when the Windows Forms designer is open.
