The following members return GaugeExportContext objects:
Use the XRDashboardGauge object to customize the printable gauges.
The following image illustrates elements of the printable gauge:
The following example illustrates how to customize the Gauge dashboard item in the exported document when you handle the DashboardDesigner.CustomExport / DashboardViewer.CustomExport events. You can use the CustomExportEventArgs.GetPrintableControls method to obtained the printable controls.
