My specific case was a bit more complex because I was binding to the page View Model (which I didn’t want to instantiate more than once as it made web service calls) to a Combo Box in a Data Template for a cell in a Grid View.There wasn’t much documentation regarding that which I found that was helpful, so I’ll do another post about that later.I'd start by making a Data Template for the cell as a resource: Welcome, my name is Paul Stovell.I live in Brisbane and work on Octopus Deploy, an automated deployment tool for . Prior to founding Octopus Deploy, I worked for an investment bank in London building WPF applications, and before that I worked for Readify, an Australian . I also worked on a number of open source projects and was an active user group presenter. We used the ICustom Type Descriptor interface for such a task but that will get messy fast.Then there are some problems (like this and this) where WPF leaks for you too.Finally, there are things (this, this, this, this, this, and this) that simply perform worse than you likely expect.

The idea is to make sure each concern has a single, well-defined purpose and to find a balanced way to separate these features and concepts into different modules.This ultimately reduces duplicate code and keeps the modules decoupled from each other, making our application maintainable and manageable.As a very basic example of So C, think about HTML, CSS and Java Script, where all these technologies have a well-defined purpose.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.This article shows how to get started with MVVM development for WPF applications.Scrollbar performance is often a big problem in larger WPF apps because of problems that seem trivial for small collections, but suddenly blow up with larger data sets.
