ASPxCardViewBehaviorSettings.AllowFocusedCard Property

Gets or sets whether the focused card is displayed.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v23.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

[DefaultValue(false)]
public bool AllowFocusedCard { get; set; }

VB.NET

<DefaultValue(False)>
Public Property AllowFocusedCard As Boolean

Property Value

Type	Default	Description
Boolean	false	true to display the focused card; otherwise, false.

Property Paths

You can access this nested property as listed below:

Library	Object Type	Path to AllowFocusedCard
ASP.NET MVC Extensions	CardViewSettings	.SettingsBehavior .AllowFocusedCard
ASP.NET Web Forms Controls	ASPxCardView	.SettingsBehavior .AllowFocusedCard

Remarks

If the AllowFocusedCard property is set to false, the focused card feature is disabled. In this instance, the ASPxCardView.FocusedCardIndex property’s value is always -1 and the ASPxCardView.FocusedCardChanged event isn’t raised. The style settings used to paint the focused card are not used. To identify the card currently being edited, use the ASPxCardView.EditingCardVisibleIndex property.

Example

The example below uses two ASPxCardView controls to display master-detail data.
