Comentários

OwnerRetorna a ToolStrip coleção cujos itens contém o atual ToolStripItem.Owner returns the ToolStrip whose Items collection contains the current ToolStripItem. Essa é a melhor maneira de referenciar ImageList ou de outras propriedades no nível ToolStrip superior sem escrever código especial para lidar com o estouro.This is the best way to reference ImageList or other properties in the top-level ToolStrip without writing special code to handle overflow.

O Owner permanece o mesmo, mesmo que o item se enquadrar ToolStripOverflowno.The Owner remains the same even if the item falls into the ToolStripOverflow. O Owner pode ser null para determinados DisplayedItems elementos que estão na coleção, mas não na Items coleção.The Owner can be null for certain elements that are in the DisplayedItems collection but not in the Items collection.
