Wpf canexecute not updating
We try to break things now rather than later, when we release version 1.0 (which is hopefully soon). Yup, it doesn’t work like you would probably expect. My gut is telling me to drop the Execute(T parameter) signature from Delegate Command, and just standardize on the ICommand. This is what every other Command in every other MVVM framework does.You can write your classes to handle specific commands, or not, and even indicate if those commands can be executed.The problem, much like the others we've seen, occurs when these bindings leave unwanted strong references lying around.
Show Metro Dialog Async(new Custom Base Metro Dialog()); // create and show custom dialog with own settings await this.
WPF and Silverlight allow you to define your user interface and bind it to data with a minimum of code, meaning that you can also introduce memory leaks into your application without even realizing it.
And because Silverlight and WPF applications are state-full, and allow us to hold state in the form of complex data structures as well as rich UI elements, this can add to the size of memory leaks when things go wrong. NET applications, and a common oversight by developers.
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.
