Gets or sets a condition that allows the behavior to execute the CompositeCommand. This is a dependency property.

Namespace: DevExpress.Mvvm.UI

Assembly: DevExpress.Xpf.Core.v24.1.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

C#

public CompositeCommandExecuteCondition CanExecuteCondition { get; set; }

VB.NET

Public Property CanExecuteCondition As CompositeCommandExecuteCondition

Property Value

Type	Default	Description
CompositeCommandExecuteCondition	@DevExpress.Mvvm.UI.CompositeCommandExecuteCondition.AllCommandsCanBeExecuted	A CompositeCommandExecuteCondition enumeration value.

Available values:

Name	Description
AllCommandsCanBeExecuted	The behavior can execute the CompositeCommand if all its commands are executable.
AnyCommandCanBeExecuted	The CompositeCommand can be executed if at least one of its aggregated commands is executable.

Remarks

The default CanExecuteCondition property value (AllCommandsCanBeExecuted) indicates that the composite command executes only when each of its aggregated commands is executable (the CommandItem.CanExecute property is true).

Set the CanExecuteCondition property to AnyCommandCanBeExecuted to allow the CompositeCommandBehavior to execute a CompositeCommand when at least one of its aggregated commands is executable (the CommandItem.CanExecute property is true).
