En el ejemplo de código siguiente se muestra cómo usar el Owner propiedad para la representación personalizada.The following code example demonstrates how to use the Owner property for custom rendering. Este ejemplo de código forma parte de un ejemplo más extenso proporcionado para el ToolStripItem clase.This code example is part of a larger example provided for the ToolStripItem class.

// This method defines the painting behavior of the control.

// Draws the item's background image.
// Draws the item's image.

// Drawing operations are implemented in the

Comentarios

Owner Devuelve el ToolStrip cuya colección de elementos contiene actual ToolStripItem.Owner returns the ToolStrip whose Items collection contains the current ToolStripItem. Esta es la mejor manera para hacer referencia a ImageList u otras propiedades en el nivel superior ToolStrip sin necesidad de escribir código especial para controlar el desbordamiento.This is the best way to reference ImageList or other properties in the top-level ToolStrip without writing special code to handle overflow.

El Owner sigue siendo la misma incluso si el elemento se divide en las ToolStripOverflow.The Owner remains the same even if the item falls into the ToolStripOverflow. El Owner puede ser null para ciertos elementos que se encuentran en el DisplayedItems colección, pero no en el Items colección.The Owner can be null for certain elements that are in the DisplayedItems collection but not in the Items collection.
