View source

Summary: Binds a command from a view model to a control on a view.

Type parameters

Name	Description
`TView`	The type of the view.
`TViewModel`	The type of the view model.
`TProp`	The type of the command property.
`TControl`	The type of the control.

Parameters

Name	Type	Description
`view`	`TView`	The view to bind to.
`viewModel`	`TViewModel?`	The view model containing the command.
`propertyName`	Expression>	An expression that selects the command property on the view model.
`controlName`	Expression>	An expression that selects the control on the view.
`toEvent = null`	string?	The event name to bind to. If null, a default event is selected.
`propertyNameExpression = ""`	string	The caller argument expression for `propertyName`. Auto-populated by the compiler.
`controlNameExpression = ""`	string	The caller argument expression for `controlName`. Auto-populated by the compiler.
`callerFilePath = ""`	string	The source file path of the caller. Auto-populated by the compiler.
