Remarks

For information and an example of how default menu item captions can be changed, see How to: Localize a Grid by Replacing Specific Strings at Runtime.

Example

The following example demonstrates how to customize the grid’s context menu at runtime. For instance this sample demonstrates how to remove the default ‘Show Column Chooser’ menu item from the Column Context Menu, and add a custom item instead.

For this, it is necessary to handle the DataViewBase.ShowGridMenu event. In the event handler, all modifications to the list of menu items can be done by changing the GridMenuEventArgs.Customizations collection. To remove a specific menu item along with its link, use the RemoveBarItemAndLinkAction instance, and to add a custom menu item, a new BarButtonItem object must be added to the e.Customizations collection.
