示例1: DelayBinding
protected DelayBinding(BindingExpressionBase bindingExpression, DependencyObject bindingTarget, DependencyProperty bindingTargetProperty, TimeSpan delay)
{
_bindingExpression = bindingExpression;
_delay = delay;
// Subscribe to notifications for when the target property changes. This event handler will be
// invoked when the user types, clicks, or anything else which changes the target property
_descriptor = DependencyPropertyDescriptor.FromProperty(bindingTargetProperty, bindingTarget.GetType());
// Add support so that the Enter key causes an immediate commit
bindingTarget.SaftyInvoke<FrameworkElement>(el =>
{
el.Loaded += OnBindingTargetLoaded;
});
// Setup the timer, but it won't be started until changes are detected
_timer = new DispatcherTimer();
_timer.Tick += TimerTick;
_timer.Interval = _delay;
