ASPxClientDashboardItemWidgetEventArgs Class

Provides data for events related to client widgets used to visualize data in dashboard items.

Declaration

declare class ASPxClientDashboardItemWidgetEventArgs extends ASPxClientEventArgs

Remarks

The Web Dashboard uses DevExtreme widgets to visualize data within dashboard items. The ASPxClientDashboard.ItemWidgetCreated event allows you to access these widgets and customize their settings if necessary.

The ASPxClientDashboardItemWidgetEventArgs.ItemName property returns the component name of the dashboard item whose widget may be customized. Use the ASPxClientDashboardItemWidgetEventArgs.GetWidget method to access the corresponding underlying widget. You can change the widget setting or handle its events. To unsubscribe from widget events, handle the ASPxClientDashboard.ItemBeforeWidgetDisposed event.

The following table lists dashboard items for which access to client widgets is provided.
