Examples

The following code example demonstrates how to create a collection of DesignerActionItem objects.

For a full example of implementing smart tags, see How to: Attach Smart Tags to a Windows Forms Component.

public override DesignerActionItemCollection GetSortedActionItems()
{
    DesignerActionItemCollection items = new DesignerActionItemCollection();

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

    //Boolean property for locking color selections.
    items.Add(new DesignerActionPropertyItem("LockColors",
                     "Lock Colors", "Appearance",
                     "Locks the color properties."));

Remarks

Like the DesignerActionTextItem base class, DesignerActionHeaderItem represents individual static text items in a smart tag panel. However, DesignerActionHeaderItem entries are displayed using bold text. Typically, a header item is used to create a heading for a group of items in a panel. Clicking on a header item causes no action.

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