Public Enum UpdateSourceTrigger
- Inheritance
Name | Value | Description |
---|---|---|
Default | 0 | The default UpdateSourceTrigger value of the binding target property. The default value for most dependency properties is PropertyChanged, while the Text property has a default value of LostFocus. |
PropertyChanged | 1 | Updates the binding source immediately whenever the binding target property changes. |
LostFocus | 2 | Updates the binding source whenever the binding target element loses focus. |
Explicit | 3 | Updates the binding source only when you call the UpdateSource() method. |
A programmatic way to determine the default UpdateSourceTrigger
value of a dependency property is to get the property metadata of the property using DependencyProperty.GetMetadata, and then to check the value of the FrameworkPropertyMetadata.DefaultUpdateSourceTrigger property.
For more information, see Binding.UpdateSourceTrigger.
