You can force WPF to update a binding by calling
BindingExpression.UpdateTarget(and, for certain bindings,BindingExpression.UpdateSource). If the binding involves a converter, then the converter will run as part of that update.To get the BindingExpression for a bound property, call
BindingOperations.GetBindingExpression.
