Event Data

The DashboardItemControlUpdated event's data class is DashboardItemControlEventArgs. The following properties provide information specific to this event:

Property	Description
CardControl	Gets an underlying Card control.
ChartContext	Gets the chart context.
ChartControl	Gets an underlying chart control.
DashboardItemName	Gets the component name of the dashboard item for which the event was raised.
DateFilterControl	Gets an underlying date filter control.
GaugeContext	Gets the gauge context.
GaugeControl	Gets an underlying gauge control.
GridContext	Gets the grid context.
GridControl	Gets an underlying grid control.
MapControl	Gets an underlying map control.
PictureEdit	Gets an underlying picture edit control.
PivotGridControl	Gets an underlying PivotGridControl.
RichEditControl	Gets an underlying RichEdit control.
TreeMapControl	Gets an underlying TreeMap control.

Example

The following code snippets shows how to customize the controls used to visualize data in the dashboard items at runtime.

The following options are changed:

• Grid: The font is changed to “Arial, 10”. For this, handle the DashboardDesigner.DashboardItemControlUpdated event and access the control’s MainView.
• Chart: The background color of the chart pane is set to LightYellow. For this, handle the DashboardDesigner.DashboardItemControlUpdated event and access the control’s Diagram property.
• Pivot: Cell values related to “Mountain” products are hidden, ### is displayed instead. The PivotGridControl.CustomCellValue, DashboardDesigner.DashboardItemControlCreated and DashboardDesigner.DashboardItemBeforeControlDisposed events are handled to customize the cell values.
• Gauge: The background color of the first gauge’s label is set to “LightGreen”, a custom label is set and displayed in “Tahoma, 16” font. The number of major ticks is set to 8. For this, handle the DashboardDesigner.DashboardItemControlUpdated event and use the Gauges property to access the collection of gauges displayed in the control.
