I am creating a user control and would like to create a custom menu like this http://i56.tinypic.com/5ycaq开发者_如何学JAVAb.png but I do not know what to do, can you help me? (Sorry for my bad English)

You want to look into DesignerActionList.

Specifically in your ControlDesigner (or the one that you have that extends from it), you'll need to override

public virtual DesignerActionListCollection ActionLists { get; }
