Public Property CanExecuteCondition As CompositeCommandExecuteCondition
| 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.
|
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).
The following code snippet (auto-collected from DevExpress Examples) contains a reference to the CanExecuteCondition property.
