Wpf binding not updating property
And strong references preventing garbage collection are just memory leaks by another name.Command binding allows you to separate common application commands (and their invocation) from where they are handled.To unblock a file, right click on it, and select properties, and then select the ‘unblock’ button. In Win Forms, there's a control called the Timer, which can perform an action repeatedly within a given interval.The tick operations are placed on the Dispatcher queue, so if the computer is under a lot of pressure, your operation might be delayed. NET framework promises that the Tick event will never occur too early, but can't promise that it won't be slightly delayed.
The Dispatcher Timer is not started before you call the Start() method or set the Is Enabled property to true.WPF has this possibility as well, but instead of an invisible control, we have the Dispatcher Timer control.It does pretty much the same thing, but instead of dropping it on your form, you create and use it exclusively from your Code-behind code.To show what the Dispatcher Timer is capable of, let's try updating more frequently... As you can see, we now ask the Dispatcher Timer to fire every millisecond!In the Tick event, we use a custom time format string to show the milliseconds in the label as well.
