System_CAPS_noteNote

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

All toolbox items associated with an Activity class are derived from ActivityToolboxItem. This class displays a graphical representation of an Activity class in the toolbox of a design-time environment and creates an instance of the Activity class it is associated with when a user drags it onto the design surface. The activity toolbox item typically represents an activity to create when invoked on a design-mode document.

This class inherits directly from the ToolboxItem class.

The following example shows a complete ActivityToolboxItem class for a custom activity. In this example, the CreateComponentsCore method is overridden in order to place 2 custom activities within a ParallelActivity.

[Serializable]
internal sealed class CustomActivityToolboxItem : ActivityToolboxItem
{
    public CustomActivityToolboxItem(Type type)
        : base(type)
    {
    }

    private CustomActivityToolboxItem(SerializationInfo info, StreamingContext context)
    {
        Deserialize(info, context);
    }

    protected override IComponent[] CreateComponentsCore(IDesignerHost designerHost)
    {
        CompositeActivity parallel = new ParallelActivity();
        parallel.Activities.Add(new CustomActivity());
        parallel.Activities.Add(new CustomActivity());

        return new IComponent[] { parallel };
    }
}
