protected static IDisposable ForEvent(ICommand? command, object? target, IObservable<object?> commandParameter, string eventName, PropertyInfo enabledProperty)

View source

Summary: Creates a commands binding from event and a property.

Parameters

Name	Type	Description
`command`	ICommand?	Command.
`target`	object?	Target.
`commandParameter`	IObservable	Command parameter.
`eventName`	string	Event name.
`enabledProperty`	PropertyInfo	Enabled property name.

Returns: IDisposable -- The binding from event.

2. Overload¶

protected static IDisposable ForEvent<TEventArgs>(ICommand? command, object? target, IObservable<object?>? commandParameter, Action<EventHandler<TEventArgs>> addHandler, Action<EventHandler<TEventArgs>> removeHandler, Action<object?, object?, object?[]?>? enabledSetter) where TEventArgs : EventArgs

View source

Summary: Creates a command binding from an event using explicit add/remove handler delegates and optionally synchronizes an enabled property with CanExecute.

Type parameters

Name	Description
`TEventArgs`	The event arguments type.

Parameters

Name	Type	Description
`command`	ICommand?	The command to bind.
`target`	object?	The event source object.
`commandParameter`	IObservable?	Observable producing command parameter values. If `null`, `target` is used.
`addHandler`	Action>	Adds the handler to the event source.
`removeHandler`	Action>	Removes the handler from the event source.
`enabledSetter`	Action?	Optional setter for an enabled-like property. If `null`, enabled synchronization is skipped. The setter is expected to accept `target` as the first argument and a Boolean value as the second.

Returns: IDisposable -- A disposable that unbinds the command and stops enabled synchronization.

Exceptions

Type	Condition
System.ArgumentNullException	Thrown when `command` is `null`.
