DashboardSpecialValues Class

Provides access to dashboard special values.

#Declaration

TypeScript
declare class DashboardSpecialValues

#Remarks

Fields exposed by the DashboardSpecialValues class are introduced to identify various special values (such as null or Others values) that can be displayed within the dashboard. For instance, these values can be returned when performing the following actions.

Warning

A use of ASPxClientDashboard API reduces flexibility when you configure the control. The DashboardControl underlies the ASPxClientDashboard object. The control provides access to all client settings and allows you to implement complex scenarios. We recommend that you use the DashboardControl API to configure the Web Dashboard on the client. More information: Client-Side Functionality.
