Wpf label content not updating dating wagner ware skillet
So I needed to achieve both these situation together, I needed to access Main label from a different class which is created on different thread rather than in main thread. application works on the principle of Thread affinity which means other threads can't interact with each other. Sometimes developers need to manage the thread or update WPF UI.By using INotify Property Changed you can utilize the List collection to bind to your List Box's Items Source and update the bound collection on code behind that eliminate your UI thread attachment requirement.For some reason the label only gets updated to "Done" after the execute Long Task() method is completed.
Text property has a default Update Source Trigger value of Lost Focus.WPF is really awesome to build reactive applications and data binding is here to push useful information inside of the User Interface.All is done magically and it’s wonderfully simple to create an application without knowledge of the internals of the WPF’s rendering.To make it work, I started the job in the Content Changed method to be sure the content is rendered once first.
Notice that it’s necessary only when you need to execute a long-running job on the UI-thread.
Now, I wan’t to talk about something which can useful in every WPF application : how to wait for the rendering UI to be done.
