BindingExpression<TSource, TOwner, TValue>

A typed binding whose observable path can still be extended or configured.

public sealed class BindingExpression<TSource, TOwner, TValue> : BindingExpression<TValue?> where TSource : class where TOwner : class?

Type parameter	Summary
(class) `TSource`	The root binding source type.
(class?) `TOwner`	The object that owns the selected value.
`TValue`	The selected source value type.

Methods

Converts source values before applying them to the control.

public ConvertedBindingExpression<TSource, TOwner, TValue, TTarget> ConvertTo<TTarget>(
  Func<TValue, TTarget> convert)

Parameter	Summary
`Func<TValue, TTarget>` `convert`	Converts source values to control values.

Type parameter	Summary
`TTarget`	The control value type after conversion.

Returns

ConvertedBindingExpression<TSource, TOwner, TValue, TTarget>: A converted one-way binding that can optionally be completed as two-way.

Reads once whenever a binding context attaches, without observing later changes.

public OneTimeBindingExpression<TSource, TValue> Once()

Returns

OneTimeBindingExpression<TSource, TValue>: A one-time binding that can still convert its control value.

Adds control-to-source updates to this binding.

public TwoWayBindingExpression<TSource, TOwner, TValue> TwoWay(
  Action<TOwner, TValue> write)

Parameter	Summary
`Action<TOwner, TValue>` `write`	Writes the control value to the object that owns the selected property.
