ToolboxService.CreateItemContainer Method (ToolboxItem, IDesignerHost)
Creates a new toolbox item container from a toolbox item.
Assembly: System.Drawing.Design (in System.Drawing.Design.dll)
protected virtual ToolboxItemContainer CreateItemContainer( ToolboxItem item, IDesignerHost link )
- Type: System.Drawing.Design.ToolboxItem
The toolbox item for which to create an item container.
- Type: System.ComponentModel.Design.IDesignerHost
An optional designer host that should be linked to this toolbox item. This parameter can be null.
Return ValueType: System.Drawing.Design.ToolboxItemContainer
A new toolbox item container.
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.
If the provided IDesignerHost link parameter is assigned, it indicates that this is a linked toolbox item.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.
