Are the styles available hardcoded?
I created a new style folder and copied over the contents of one style fold to the new one.
Then I edited css file name to reflect what I wanted to call the style.
Yet when I set the style in the grid using the new style it seems KG does not know what it is.
What is the correct procedure to create a new style?

I created a new style for the koolgrid.
1. Copied css folder to new folder. (Default style) Make sure it is in the same directory so it functions the same as the other styles.
2. Changed name of folder Default to Blitzer.
3. Renamed all css classes with the word default to blitzer.
4. Assigned blitzer to the grid style when creating the grid object.
Works great!
If you can't get it to work, I'm sure the koolphp guys can help as well, or I can send you my blitzer grid folder.

I did not notice that the class names had to be edited, that would explain why I felt they were "coded".
I'll try your steps and see how I make out.
Thanks.

Anthony steps are correct. The style folder name, the name of css file and the prefix classname must be the same. The prefix class name is needed to avoid style conflict if you use many grids on a page and each grid has its own style.
