public event CustomizeDashboardTitleEventHandler CustomizeDashboardTitle
Public Event CustomizeDashboardTitle As CustomizeDashboardTitleEventHandler
The CustomizeDashboardTitle event's data class is CustomizeDashboardTitleEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| FilterText | Gets or sets the text displayed in the dashboard title or in the dashboard item caption. The text identifies a single master filter value applied to the dashboard. Inherited from CustomizeDashboardCaptionBaseEventArgs. |
| Items | Provides access to command buttons located in the dashboard title or in the dashboard item’s caption. Inherited from CustomizeDashboardCaptionBaseEventArgs. |
| Text | Gets or sets the text displayed in the dashboard title or the dashboard item caption. Inherited from CustomizeDashboardCaptionBaseEventArgs. |
The DashboardDesigner.CustomizeDashboardTitle event is raised when the dashboard is loaded (the DashboardDesigner.Dashboard property is changed) or when end-user activities affect the dashboard title. Such activities include applying a master filter, performing drill-down or changing the parameter value.
You can change displayed text, remove existing buttons, add custom buttons or command bar items, including drop-down menus.
The following code snippets demonstrate how to load data in the Dashboard designer on demand when all required filters are set. For this, the Show Data button is created in the DashboardDesigner.CustomizeDashboardTitle event handler.
