* there's no attribute class named simply 'Designer'). The compiler adds the 'Attribute' to the end for us (assuming * note that in C#, I can refer to the 'DesignerAttribute' class within the To be more specific, the ToolStrip control (and by inheritance, the MenuStrip control) has a DesignerAttribute that references a class called ToolStripDesigner.

The ComponentDesigner class has a public virtual property called AssociatedComponents, which is meant to be overridden in derived classes to return a collection of references to all 'child' components of this one.

Most controls that use a custom IDesigner use one that derives from ControlDesigner, which itself derives from ComponentDesigner. There's indeed quite a lot you can do with an IDesigner, but right now we're only interested in one thing. In effect, this class controls certain aspects of the designer and of the design-time behavior of the component. This attribute, if present, provides the name of a class-an IDesigner-the designer can use to interface with the component. (Those unfamiliar with attributes might want read up on them before continuing.) When the Visual Studio designer loads a component (usually a control, but also things like Timer and such), it looks for a custom attribute on the class of type DesignerAttribute. To prevent confusion as to which I am referring to at any given time, I will always refer to the designer functionality within Visual Studio as 'the designer', and I will always refer to a designer class as an 'IDesigner', which is the interface each must implement. A warning, though: what follows is a little complicated, and might not be worth the effort.īelow, I will be referring to both the designer within Visual Studio-which is the name used to refer to the functionality within Visual Studio by which the layout and content of forms and controls are edited visually-and to designer classes-which will be explained below. and from the proprieties change the borderStyle to fixed 3d so it cannot be resized. I believe the VS designer does it by getting an instance of the control's designer (see the Designer attribute), and, if the designer is a ComponentDesigner, getting the AssociatedComponents property.
