    //Define static section header entries.
    items.Add(new DesignerActionHeaderItem("Appearance"));
    items.Add(new DesignerActionHeaderItem("Information"));

    //Boolean property for locking color selections.

                     "Lock Colors", "Appearance",

Remarks

The DesignerActionMethodItem class represents individual items in a smart tag panel. An item of this type is displayed as an active user interface element, such as a hyperlink, that invokes a programmer-supplied method in a class derived from DesignerActionList. The association between the item and the method is maintained through the value of the MemberName property. The method that this item invokes must neither take parameters nor return a value.

Individual panel items are associated together to form a panel by a call to the GetSortedActionItems method of the DesignerActionList class.

Constructors

DesignerActionMethodItem(DesignerActionList, String, String)	Initializes a new instance of the DesignerActionMethodItem class, with the specified method and display names.
