Property Value
| Type | Description |
|---|---|
| CardCollection | A collection of Card objects that provide data for calculating values displayed within cards. |
Remarks
Use the Cards property to provide data for the CardDashboardItem. Each Card object in the Cards collection contains two measures: the KpiElement.ActualValue and the KpiElement.TargetValue. These measures are used to calculate the actual and target values. Cards displayed within the CardDashboardItem display the difference between these values.
You can specify the type of summary function calculated against each measure using the Measure.SummaryType property. To specify how the difference between actual and target values should be displayed, use options exposed by the KpiElement.DeltaOptions property.
The CardDashboardItem creates a single card for each element in the Cards collection if no series dimensions are specified. Otherwise, if the SeriesDashboardItem.SeriesDimensions collection is not empty, the dashboard item creates multiple cards for each Card object, so that each card corresponds to a particular dimension value (or a combination of values, if several dimensions are added). If, at the same time, there are several Card objects within the Cards collection, cards that correspond to different Card objects are not displayed within a single screen but constitute several views. To switch between them, use the Other Cards button located on the bottom toolbar.
