WPF code-behind for resources?

Question

Hi all,

I'm working on a wpf application, and up until recently, I had a ResourceDictionary inside my main window's resources part of the xaml. The resource dictionary contained an DataTemplate that was used to style several listboxes in the window. The xaml for this datatemplate contained pointers to event handlers, eg:

<Button n:Name="btnClickMe" Content="Click Me!" LeftMouseButtonUp="btnClickMe_Click" />

I recently decided to split the content of the window up into separate user controls, and to move my ResourceDictionary into it's own file. But, of course, there isn't a code-behind file for a resource dictionary file. How can I wire this up, with things split up as I've described?

Thanks in advance!

Answer 1

You can add a code-behind to a ResourceDictionary; just make sure your class names are referenced correctly. For instance, in the ResourceDictionary if you were working with AppStyles.xaml the XAML file would have a class of:

x:Class="Client.App.Shell.themes.AppStyles"

In the code-behind, AppStyles.xaml.cs, you would make sure to have the class:

namespace Client.App.Shell.themes
{
    public partial class AppStyles
    ...

You should consider using RoutedCommands, I am thinking. there are many many resources online, here are a couple that might help you.

You can add a new class and name it with the same name as your resource dictionary plus the .cs extension and Visual Studio will automatically set things up so it becomes the code behind file.

For example if you have a resource dictionary called Buttons.xaml, add a file called Buttons.xaml.cs.
