The previously referenced article demonstrates how to modify the background of a row, when it enters a particular state. If you take a look at the default template of GridViewRow, you may see different Border elements which appeared in the corresponding state.
The referred resources ItemOuterBorder_Over, ItemBackground_Over are used to paint the outer border and the background of a row, when the mouse is over it. The same is valid for the resources named ItemOuterBorder_Selected, ItemBackground_Selected which are used to paint the outer border and the background of a row, when it is being selected. Following this logic you may modify the brushes for the rest RadGridView's parts in their particular state. As I can understand you want to modify these effects in all RadControls/WPF. For that purpose you should create your own custom theme based on Vista and modify the resources you need from there. From the following forum thread you may download a runnable project which demonstrates how this can be achieved. For those clients who do not use Microsoft Expression Blend we offer our themes as separate projects. You may access the xaml files for all themes from the Themes folder of your personal installation.
