I just downloaded the nice themes collection from the Codeplex WPF Themes site. I like the WhisterBlue and BureauBlue themes a lot, but neither contain any styles for the new controls included in the WPF Toolkit (DataGrid, DatePicker, and Calendar).
It seems like someone out there must have extended the themes to cover these controls, but I've had no luck finding them. So, if you have any leads, I'd love to hear them.
I should also mention that I've been trying to port a Silverlight version of the BureauBlue DataGrid theme to WPF (see: How do you port a theme from Silverlight to WPF?), but that has been quite unsuccessful so far.
WPFreakyStyley has extended all of its themes to the WPF Toolkit. You might be able to find one that matches the CodePlex theme you're using. WPFreakyStyley
The WhistlerBlue theme is included in the Silverlight toolkit Oct 2009 in the preview band.
Actipro Software has a free, opensource project on CodePlex called the "WPF Control Contrib". It contains code that extends the functionality of the built-in DataGrid and includes five themes for the DataGrid: AeroNormal, Classic, LunaHomestead, LunaMetallic and LunaNormal
High Robotics has free WPF theme that can be applied to apps and does not have dolly glossy style.
But it requires at least WPF.NET 4 (WPF Toolkit was included in that version).
Also here is discussion about free wpf themes (MahApps.Metro, nukeaction and others).
