There is no shortage of information out there on how to speed up the performance of WPF applications, but too often the focus is on the weird stuff instead of the simpler issues.I’m not going to talk about things like writing to to optimize drawing—it’s a topic covered to death elsewhere.

Data Binding Overview Binding Sources Overview Data Templating Overview Binding Declarations Overview How-to Topics System. Content Controls such as Button and Items Controls such as List Box and List View have built-in functionality to enable flexible styling of single data items or collections of data items.This topic first discusses concepts fundamental to WPF data binding and then goes into the usage of the Binding class and other features of data binding.Data binding is the process that establishes a connection between the application UI and business logic.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.

This is a much more user friendly display and will do just fine in some cases, but relying on a simple string is not that flexible.

Perhaps you want a part of the text to be bold or another color? Fortunately, WPF makes all of this very simple using templates.

Sort, filter, and group views can be generated on top of the data.

The data binding functionality in WPF has several advantages over traditional models, including a broad range of properties that inherently support data binding, flexible UI representation of data, and clean separation of business logic from UI.

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.
