SPSite oSiteCollection = SPContext.Current.Site;
using(SPWeb oWebsite = oSiteCollection.AllWebs["Website_Name"])
   SPList oList = oWebsite.Lists["List_Name"];
   SPView oView = oList.Views["View_Name"];

    oView.GroupByHeader = 
   "<HTML><![CDATA[<TBODY id=\"titl]]></HTML>" +
   "<GetVar Name=\"GroupByLevelString\" />" + 
   "<HTML><![CDATA[\"><TR STYLE=\"font-size:14pt;color:red\"]]></HTML>" 
   "<Switch><Expr><GetVar Name=\"GroupByIndent\" /></Expr>
      <Case Value=\"0\">" +
