Commenti

Impostare il AllowDrop proprietà true e impostare il AllowItemReorder proprietà false per rispondere al comportamento di trascinamento e rilascio è stato definito nel Control.DragEnter, Control.DragLeave, e Control.DragDrop eventi.Set the AllowDrop property to true and set the AllowItemReorder property to false to respond to drag-and-drop behavior you have defined in the Control.DragEnter, Control.DragLeave, and Control.DragDrop events.

Impostare AllowDrop al false e impostare AllowItemReorder al true per fare in modo il ToolStrip classe per la gestione di trascinamento e rilascio e ridisposizione degli elementi automaticamente.Set AllowDrop to false and set AllowItemReorder to true to cause the ToolStrip class to handle drag-and-drop and item reordering automatically. Impostare AllowItemReorder al true per due ToolStrip oggetti per consentire il trascinamento di elementi da un ToolStrip a altro.Set AllowItemReorder to true for two ToolStrip objects to allow dragging of items from one ToolStrip to the other. Per abilitare l'impostazione predefinita e trascinamento, deve essere premuto il tasto ALT durante l'operazione di trascinamento.To enable the default drag-and-drop, the ALT key must be pressed during the drag operation.

Se si impostano entrambe AllowDrop e AllowItemReorder a true genera un'eccezione.Setting both AllowDrop and AllowItemReorder to true throws an exception.
