How to handle them may vary, depending on what you're doing and what you're looking to accomplish, but WPF comes with two very easy solutions that you can use: The Observable Collection and the INotify Property Changed interface.The following example will show you why we need these two things: Try running it for yourself and watch how even though you add something to the list or change the name of one of the users, nothing in the UI is updated.The Margin property tells the location of a List Box on the parent control.The Horizontal Alignment and Vertical Alignment properties are used to set horizontal and vertical alignments.The problem is that none of the buttons seems to work. The first step is to get the UI to respond to changes in the list source (Items Source), like when we add or delete a user.What we need is a list that notifies any destinations of changes to its content, and fortunately, WPF provides a type of list that will do just that.So far in this tutorial, we have mostly created bindings between UI elements and existing classes, but in real life applications, you will obviously be binding to your own data objects.This is just as easy, but once you start doing it, you might discover something that disappoints you: Changes are not automatically reflected, like they were in previous examples.
I will definitely look into this solution and that one provided by tawani. Property Changed' C:\Users\MVVM\View Model\I assume I have to add an event handler per: I would love to see this work. Or, maybe the delta between lower case records and upper case Records?
When building an application, I might not have the luxury of creating model classes to represent the objects I'll be rendering on screen, because they are dynamic.
If I don't know the shape of my data, I can use a meta model (a model of the final model) to represent it.
The example is pretty simple, with a User class that will keep the name of the user, a List Box to show them in and some buttons to manipulate both the list and its contents.
The Items Source of the list is assigned to a quick list of a couple of users that we create in the window constructor.
