DashboardDesigner.CustomizeDashboardItemCaption Event

Allows you to customize the dashboard item caption at runtime.

Namespace: DevExpress.DashboardWin

Assembly: DevExpress.Dashboard.v18.1.Win.dll

Declaration

public event CustomizeDashboardItemCaptionEventHandler CustomizeDashboardItemCaption
Public Event CustomizeDashboardItemCaption As CustomizeDashboardItemCaptionEventHandler

The event handler receives an argument of the CustomizeDashboardItemCaptionEventHandler type.

This event is raised when the dashboard is loaded (the DashboardViewer.Dashboard property is changed) or when end-user activities affect the dashboard item caption. Such activities include applying master filter, performing drill-down or changing the parameter value.

You can change the displayed text, remove existing buttons, add custom buttons or command bar items, including drop-down menus.
