Wpf listview binding not updating

What is omitted from all of these is a lowest common denominator fully working example that is useful (or at least can be extended to be useful). Provide a second example that builds on the first in order to illustrate the advanced concepts like callbacks.Thanks thanks for this wonderful tutorial it really helped me a lot to understand Dependency Properties , I just still have a question , I don't understand the fact that the dependency property is declared as static so how comes that every instance has its own value this is the only misundestanding I still have I need your help , thanks in advance .Introduction Value resolution strategy The magic behind it How to create a Depdency Property Readonly Dependency Properties Attached Dependency Properties Listen to dependency property changes How to clear a local value When you begin to develop appliations with WPF, you will soon stumble across Dependency Properties. NET properties, but the concept behind is much more complex and powerful.

i mean they must be stored somewhere when application runs, so where would that be? i wanted to know how is this fact empowers DP compared to normal Prop'. so what is the difference when adding "readonly" statement in regular DP and Read Only DP? Maybe a silly question but what is the meaning of " Dependency" in Dependency Properties?

Abstract: The MVVM Light toolkit provides a lot of boiler plate code to implement Model-View-View Model based applications quickly and gives the user the freedom to customize and design the application.

Maybe you ask yourself, why not just use a normal . One important reason is that you cannot set triggers on normal . Creating a read only property is similar to creating a regular Dependency Property. This key should be stored in a private or protected static readonly field of your class.

The key gives you access to set the value from within your class and use it like a normal dependency property.

This article shows how to get started with MVVM development for WPF applications.

Separation of Concerns (decoupling) or So C is a principle that promotes best practices for software architecture.

In this case we can coerce the value within the allowed boundaries.

In the following example we limit the time to be in the past. Is does not make sense to provide a setter for this value.

Also, i couldn't use 'Listen to dependency property changes' section. I understand that when storring only changes it reduces memory storage but what does it mean that the default values are "stored within the dependency property"? You wrote that DP are stored in Dictionary instaed of Field like Normal properties. I understood that there are " Readonly DP" but i have noticed that when using the shortcutin Visual Studio for creating regular DP (propdp) a " public static readonly Dependency Property My Property" is added. At the begining when you expalnied about the advantages one of them was " Reduced memory footprint" u wrote that when using DP it reduces memory storage compare to Normal Properties because it "only stores modified properties in the instance & The default values are stored once within the dependency property". why when updating data from Model to View we have to use DP or Notifty Property Change instead of normal property, and when updating data from View to Model we have to use Normal Property?

A ‘concern’ can be considered as an aspect of software functionality.
