I have a ListBox on a form that is bound to an ObservableCollection of a custom type. Within each item there is a ComboBox bound to an enumeration type.

Basically changing the ItemsPanel to point at different resources, inside the button click handler. This works fine. ...
In Expression Blend you can create a font-size of say 18 and then create a "font-size resource". Coming at this from HTML/CSS, I cannot think of when I would want to make a style for a "font-size" and one for a "font-style" and one for a "font-weight". Instead I want to make a font called "CompanyHeader" and have 10 different attributes...

Is it possible and a good idea to have user control (public MyControl: UserControl) which supports both ControlTemplates and existing content? I have understood that ControlTemplates should only be used when you inherit from Control (public MyControl: Control), but I found out that you can use them with UserControl too if your UserContro...
After reading how to keep your dev machine from slowing down, I was reminded of my good intention a year ago to build a VM for my development machine. However, I'm developing WPF and SilverLight GUIs on Vista x64. I can run x64 versions of the OS under a VM but I'm concerned about graphic performance for WPF and especially running Expre...

Currently I am using an ObservableCollection within a WPF application, the application is an implementation of Conway's Game of life and works well for about 500 cells but after that it begins to slow down significantly.

We're creating a WPF custom control targeted at .NET 3.5. It is very compelling to use StringFormat property in bindings, but this was only added in SP1. So the question is: how many potential users will we be cutting off by changing the requirement from .NET 3.5 to .NET 3.5 SP1? Or is it safe to assume that more or less every user who...
