jQuery Grid Plugin - jqGrid

Hello,

I'm very new to jqGrid. I just got it working a couple of hours ago. I have the following on my page. I hope it makes sense:

 <link   href="@Url.Content("~/Content/themes/base/jquery-ui.css")" rel="stylesheet" type="text/css" />
 <link   href='@Url.Content("~/Content/themes/redmond/jquery-ui-1.8.custom.css")' rel='stylesheet' type='text/css' />  

What I want to ask is how does jqGrid know that this is the stylesheet I want to use? I am not sure if my grid is even using this stylesheet but that's the one I downloaded. Is there some way that I tell jqGrid what style to use?

I hope someone can give me advice.

Melissa ..
