Adding Items at Design Time
To add menu items at Design Time, click on the Edit Items property to launch the RadElement Collection Editor. Click the arrow next to the Add button to add items to the menu. You can add a variety of items to the collection.
Once you have added a RadMenuItem to the collection, it will appear in the list on the left side of the dialog. Click the RadMenuItem to edit its properties in the corresponding property grid on the right of the dialog.
In the property grid you will find many of the standard control properties, including Text, to control the display text of the item and ToolTipText that displays when the mouse hovers over an item. Each RadMenuItem you add also contains an Items collection of its own, allowing you to create menu hierarchies in the RadSplitButton. You can also do the following with each item:
Associate an image to an item using the Image property or associate a standard ImageList component to the RadSplitButton and use the ImageIndex or ImageKey properties for the item.
PopupDirection determines the direction in which the sub items of a RadMenuItem will be displayed and can be Left, Right, Up or Down.
Use CheckOnClick to toggle a check mark next to a RadMenuItem. This property is appropriate to use when the item doesn't contain sub items.
