Accessing a resource via codebehind in WPF

Question

I have a custom collection defined in my window resources as follows (in a Sketchflow app so the window is actually a UserControl):

Answer 1

You should use System.Windows.Controls.UserControl's FindResource() or TryFindResource() methods.

Also, a good practice is to create a string constant which maps the name of your key in the resource dictionary (so that you can change it at only one place).
