Remarks

Use the Insert method to insert the specified MenuItemBinding object in the collection at the specified index.

Note

You can add null values and duplicate MenuItemBinding objects to the collection.

As an alternative, you can simply append a MenuItemBinding object to the end of the collection by using the Add method.

Note

The order in which MenuItemBinding objects appear in the collection has no effect on the how those objects are applied to the menu items in a Menu control.
