BindingExpression::UpdateSource Method ()
.NET Framework (current version)
Sends the current binding target value to the binding source property in TwoWay or OneWayToSource bindings.
Assembly: PresentationFramework (in PresentationFramework.dll)
| Exception | Condition |
|---|---|
| InvalidOperationException | The binding has been detached from its target. |
This method does nothing when the Mode of the binding is not TwoWay or OneWayToSource.
If the UpdateSourceTrigger value of your binding is set to Explicit, you must call the UpdateSource method or the changes will not propagate back to the source.
