Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public int MergeOrder { get; set; }

Property Value

Type: System.Int32
A zero-based index representing the merge order position for this menu item. The default is 0.

The merge order of a menu item specifies the relative position that this menu item will take if the menu structure that the MenuItem is contained in is merged with another.
