public:
property System::Windows::Data::UpdateSourceTrigger UpdateSourceTrigger { System::Windows::Data::UpdateSourceTrigger get(); void set(System::Windows::Data::UpdateSourceTrigger value); };public System.Windows.Data.UpdateSourceTrigger UpdateSourceTrigger { get; set; }member this.UpdateSourceTrigger : System.Windows.Data.UpdateSourceTrigger with get, setPublic Property UpdateSourceTrigger As UpdateSourceTriggerProperty Value
One of the UpdateSourceTrigger values. The default value is Default, which returns the default UpdateSourceTrigger value of the target dependency property. However, the default value for most dependency properties is PropertyChanged, while the Text property has a default value of LostFocus.
A programmatic way to determine the default UpdateSourceTrigger value of a dependency property is to get the property metadata of the property using GetMetadata(Type) and then check the value of the DefaultUpdateSourceTrigger property.
Remarks
The values of the Mode and UpdateSourceTrigger properties determine the functionality of the MultiBinding and are used as the default values for all the bindings in the collection unless an individual binding overrides these properties. For example, if the Mode property on the MultiBinding object is set to TwoWay, then all the bindings in the collection are considered TwoWay unless you set a different Mode value on one of the bindings explicitly. For more information, see the Binding.Mode and Binding.UpdateSourceTrigger properties.
