Fresax cam - Observablecollection listbox not updating

Instead, dependency properties are registered with the dependency property framework, and the underlying property value is resolved – meaning the value is determined by the dependency property framework based on rules defined by the property registration.

A few weeks ago, a friend convinved me to start looking into WPF, XAML and the MVVM pattern. NET Web Forms & MVC2 applications and core system design/development, I haven’t had any exposure to these new(er) technologies, and I thought it might be fun to see what all of the fuss is about. I am using terms in this post in a way which assumes that you are using the MVVM pattern.

Finally, there are things (this, this, this, this, this, and this) that simply perform worse than you likely expect.

If the framework has reached the top of the tree without finding any local values, it will then use a predefined default value as the property's value.

This method allows Dependency Properties to consume less memory than regular properties since only values that were explicitly set by the user will be stored locally.

Note: 2008 and older issues are only available as files.

On most versions of windows you must first save these files to your local machine, and then unblock the file in order to read it.

Lover of high-performance distributed architecture.

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.Note that the information in this post may also be applied to other controls implementing Items Control. Along the way, I came across a situation where I needed to do some different kinds of binding using Combo Boxes.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.Also, it can be difficult in WPF to know exactly when the system is finished with an object.For views, you get the get a WPF notification that a viewmodel is about to go unused by a view.I’m not going to talk about things like writing to to optimize drawing—it’s a topic covered to death elsewhere.
