Examples

The following code example demonstrates how to create a DesignerActionItemCollection and populate it to form a smart tag list. This code example is part of a larger example provided for the DesignerActionItem class.

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."));
    if (!LockColors)
    {
        items.Add(new DesignerActionPropertyItem("BackColor",
                         "Back Color", "Appearance",
                         "Selects the background color."));
        items.Add(new DesignerActionPropertyItem("ForeColor",
                         "Fore Color", "Appearance",
                         "Selects the foreground color."));

        //This next method item is also added to the context menu 
        // (as a designer verb).
        items.Add(new DesignerActionMethodItem(this,
                         "InvertColors", "Invert Colors",

                     "Text String", "Appearance",
                     "Sets the display text."));
