Example

The following example demonstrates how to customize the grid’s context menu at runtime. This sample removes the default Show Column Chooser menu item from the Column Context Menu and adds a custom item instead.

Handle the DataViewBase.ShowGridMenu event. In the event handler, change the GridMenuEventArgs.Customizations collection to modify the list of menu items. To remove a menu item with its link, use the RemoveBarItemAndLinkAction instance. To add a custom menu item, add a new BarButtonItem object to the GridMenuEventArgs.Customizations collection.
