namespace Noesis | MSDN

Describes a collection of Binding objects attached to a single binding target property.

Example:

<Border>
  <Border.Width>
    <MultiBinding Converter="{StaticResource AddConverter}">
      <Binding ElementName="source1" Path="Width"/>
      <Binding ElementName="source2" Path="Width"/>
    </MultiBinding>
  </Border.Width>
</Border>
<TextBlock>
  <TextBlock.Text>
    <MultiBinding StringFormat="{}{0} x {1}">
      <Binding Path="Width" />
      <Binding Path="Height" />
    </MultiBinding>

Properties


 Name Description
RO Bindings Gets the collection of Binding objects within this MultiBinding instance
None Converter Gets or sets the converter to use to convert the source values to or from the target value
None ConverterParameter Gets or sets the parameter to pass to the Converter
None Mode

Gets or sets the binding mode. It can be set to one of the following values of the BindingMode enumeration:

  • OneWay: The target is updated whenever the source changes.
  • TwoWay: A change to either the target or source updates the other.
  • OneWayToSource: The opposite of OneWay. The source is updated whenever the targetchanges.
  • OneTime: This works just like OneWay, except changes to the source are notreflected at the target. The target retains a snapshot of the source at the time the Binding is initiated.
None UpdateSourceTrigger

Gets or sets a value that determines the timing of binding source updates:

  • Default: The default UpdateSourceTrigger value of the binding target property. Thedefault value for most dependency properties is PropertyChanged, while the Text property has a default value of LostFocus.
  • PropertyChanged: The source is updated whenever the target property value changes.
  • LostFocus: When the target property value changes, the source is only updated afterthe target element loses focus.
  • Explicit: The source is only updated when you make an explicit call to*BindingExpression.UpdateSource*.
