If I understand you correctly, you want to show one or more relations in your gridview.
If this is what you want, have a look at this tutorial: http://www.yiiframework.com/wiki/281/searching-and-sorting-by-related-model-in-cgridview/
This tutorial doesn't only show you how to show a relation in your gridview but it also shows you how to sort and filter the data. good luck!
