Gets or sets a value indicating whether drag-and-drop and item reordering are handled through events that you implement.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Set to false and set AllowItemReorder to true to cause the ToolStrip class to handle drag-and-drop and item reordering automatically. Set AllowItemReorder to true for two ToolStrip objects to allow dragging of items from one ToolStrip to the other. To enable the default drag-and-drop, the ALT key must be pressed during the drag operation.
Setting both and AllowItemReorder to true throws an exception.
