The DesignerActionListCollection class represents the aggregation of all the items in a smart tag panel. The DesignerActionListCollection class contains zero or more DesignerActionList objects. Each of these lists contains zero or more objects that represent the actual items in the panel and are derived from the DesignerActionItem class.

The following table shows the two techniques for supplying a DesignerActionListCollection to populate the panel with items for components, including custom controls.

The designer infrastructure constructs a panel by creating a smart tag panel, whose constructor takes two parameters of type DesignerActionListCollection. The collections of lists, which contain the pulled and pushed items, are merged into one panel.

Because it derives from the System.CollectionsCollectionBase class, DesignerActionListCollection uses an internal ArrayList to store its collection of DesignerActionList objects.

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

private DesignerActionListCollection actionLists;

Public Overrides ReadOnly Property ActionLists() _

        If lists Is Nothing Then
            lists = New DesignerActionListCollection()

        End If 
        Return lists
    End Get 
End Property

public override DesignerActionListCollection ActionLists
{
    get
    {
        if (null == actionLists)
        {
            actionLists = new DesignerActionListCollection();
            actionLists.Add(
                new ColorLabelActionList(this.Component));
        }
        return actionLists;
    }
}
