DashboardPopupMenuShowingEventArgs Class

Namespace: DevExpress.DashboardWin

Assembly: DevExpress.Dashboard.v21.2.Win.dll

Declaration

public class DashboardPopupMenuShowingEventArgs :
    DashboardItemMouseHitTestEventArgs

Remarks

The PopupMenuShowing event occurs when a user invokes a pop-up menu in the UI. This event allows you to customize the pop-up menu that is invoked when a user right-clicks a dashboard item or clicks a command button in the dashboard title or the dashboard item caption.

Use the following properties in the PopupMenuShowing event handler to customize the pop-up menu:

The e.DashboardArea property identifies the pop-up menu’s location. The e.DashboardItemArea property gets the area of the target dashboard item.

The e.DashboardItemName property obtains the dashboard item name for which the event is raised. To identify the clicked command button, use the e.ButtonType property.

Use the e.Menu property to customize the pop-up menu. You can set the e.Allow property to false or assign null to the e.Menu property to prevent users from invoking the menu.

Example

The following example shows how to customize the Pivot dashboard item’s pop-up menu:

popup-menu-showing-pivot-example

The PopupMenuShowing event occurs each time a user invokes a pop-up menu and adds the “Custom Menu Item” link to the Pivot’s menu. Note that you need to remove the previously added “Custom Menu Item” link from BarItemLinkCollection each time the event fires. Otherwise, the pop-up menu creates “Custom Menu Item” copies.
