Card Class

A card template used to display a series of cards in the CardDashboardItem.

Namespace: DevExpress.DashboardCommon

Assembly: DevExpress.Dashboard.v20.2.Core.dll

NuGet Packages: DevExpress.Dashboard.Core, DevExpress.WindowsDesktop.Dashboard.Core

Declaration

C#

public class Card :
    KpiElement,
    ICardLayoutContext

VB.NET

Public Class Card
    Inherits KpiElement
    Implements ICardLayoutContext

Related API Members

The following members return Card objects:

• CardItemDeltaFormatRule.Card

Remarks

To create a card template in the CardDashboardItem, use the CardDashboardItem.Cards property that accepts the Card class objects. An API exposed by the Card class includes the following main members:

• The ActualValue and TargetValue properties provide measure values for a card.
• The eriesDimensions property provides dimension values that are used to create multiple cards for the predefined set of measures.
• The LayoutTemplate property allows you to customize card layouts.

Example

This example creates a Card dashboard item in code, bind it to data and customize the card layout.

To apply a custom card template, create the CardCustomLayoutTemplate instance and assign it to the Card.LayoutTemplate property of a Card object. Specify the required settings and add the Card object to the CardDashboardItem.Cards collection.
