How/Where to Find Microsoft Default Styles for WPF Controls

Question

I am looking to change the style of a control but I basically want to copy part of a default style. Does anyone know how I can figure out what the default style of a control is?

In my case I am wanting to make the column headers in a DataGrid go blue on mouse over like the row headers do.

Answer 1

You can find some templates that are very close to the defaults on this MSDN site

Another alternative is to get a copy of Expression Blend and use it to make a copy of the default style, however Blend isn't free

Answer 2

Contrary to what Rachel says, the link she provides does not provide the default templates.

I have seen using System.Windows.Markup.XamlWriter.Save(myObject.Template) that the default templates are completely different from what that site shows.
