Syntax

Copy

public DualBinding<TValue> BindDataContext<TObject>(
	Expression<Func<TObject, TValue>> propertyExpression,
	DualBindingMode mode = DualBindingMode.TwoWay
)

Public Function BindDataContext(Of TObject) ( 
	propertyExpression As Expression(Of Func(Of TObject, TValue)),
	Optional mode As DualBindingMode = DualBindingMode.TwoWay
) As DualBinding(Of TValue)

member BindDataContext : 
        propertyExpression : Expression<Func<'TObject, 'TValue>> * 
        ?mode : DualBindingMode 
(* Defaults:
        let _mode = defaultArg mode DualBindingMode.TwoWay
*)
-> DualBinding<'TValue>

Parameters

propertyExpression: Type: System.Linq.ExpressionsExpressionFuncTObject, TValue
Expression for a property of the data context, or a non-property expression with no change event binding.
mode (Optional): Type: Eto.FormsDualBindingMode
Direction of the binding

Type Parameters

TObject: Type of the data context to bind to

Return Value

Type: DualBindingTValue
The binding between the data context and this binding

Remarks

This has the advantage of registering automatically to INotifyPropertyChanged or to an event named after the property with a "Changed" suffix, if the expression is a property. When the expression does not evaluate to a property, it will not be able to bind to the changed events and will use the expression as a delegate directly.
