Wpf mvvm listview not updating Free private chat with strippers no sign up
We use a bunch of Text Block controls to build each item, where we put part of the text in bold.
For the e-mail address, which we added to this example, we underline it, give it a blue color and change the mouse cursor, to make it behave like a hyperlink.
I have a List View which i am updating as soon as i get data .
List View gets updated if i add items to observable Collection in the View Model`s constructor but not if i do it in some method after i get callback .
It exposes data relevant to the view and exposes the behaviors for the views, usually with Commands.
MODEL: A Model is responsible for exposing data in a way that is easily consumable by WPF.I have spend a lot of time on Stackoverflow and i know there are many related questions but i could not find answer .Whats bugging me is that , if it works when i add values in the constructor then why it doesnt work if i add values in the some method .In the previous article, we manually populated a List View control through XAML code, but in WPF, it's all about data binding.The concept of data binding is explained in detail in another part of this tutorial, but generally speaking it's about separating data from layout.
