Comentarios

ToolStripManager admite tareas relacionadas con ToolStrip en aplicaciones completas, como las opciones del representador, combinación y configuración. El método sobrecargado Merge combina controles ToolStrip entre sí y el método sobrecargado RevertMerge deshace una operación de combinación.

Use la ToolStripRenderer clase con la ToolStripManager clase para obtener aún más control y personalización sobre el estilo de dibujo y diseño.

Propiedades

Renderer
