DXSubMenuItem Class

Specifies a submenu.

Namespace:DevExpress.Utils.Menu
Assembly:DevExpress.Utils.v17.1.dll

Expanded Syntax

Expanded Remarks

The DXSubMenuItem class is a submenu which can contain nested menu items. You can populate the submenu with nested items via the Items property. The BeforePopup event allows you to populate the menu dynamically.

You can add the following menu items to a submenu:

DXSubMenuItem items can be added as elements to menus (DXPopupMenu objects and its descendants). See the DXPopupMenu topic for more information.

Expanded Example

The following example demonstrates how to implement a custom menu in the XtraGrid control. A menu that is created is displayed when a row in a grid's view is right-clicked. It contains a submenu with a single "Delete Row" item, and a check menu item ("Merging Enabled"). The resultant menu, painted using the Money Twins skin, is shown below:

When a grid's view is right-clicked, the GridView.PopupMenuShowing event is generated. Its Menu parameter specifies the menu which is about to be invoked, and it's possible to customize it as necessary. Note that the XtraGrid doesn't display any default menu when a row is right-clicked. The PopupMenuShowing event, however, still fires in this case and its Menu parameter refers to an empty menu. So, you can use this property to add custom menu items.

In this example three menu items are created and added to the menu:
  • the "Rows" submenu which displays the "Delete Row" menu item. A submenu is represented by the DXSubMenuItem class.
  • the "Delete Row" item, represented by the DXMenuItem class. Clicking on this item deletes the clicked row.
  • the "Merging Enabled" check item, represented by the DXMenuCheckItem class. Clicking on this item triggers the GridOptionsView.AllowCellMerge option, which specifies whether the cell merging feature is enabled
