dhtmlx Tabbar showing inorrect style

we set style “silver” for Tabbar, but when it is loaded it is not showing this style, and only after we drift mouse over tabs it is set silver style

Please be sure that style was defined ( tabbar.setStyle ) before adding tabs by addTab command or loading info from XML.

I have :

function setOnInitTab(sTab)
{
    sTab.setStyle(“silver”);
    ShowMainGrid(0);
}

<div id=“MainTabbar” enableforcehiding=“true” margin=“0” class=“dhtmlxTabBar” oninit=“setOnInitTab(MainTabbar)”
                        imgpath=“js/dhtmlxTab/codebase/imgs/” skincolors="#FCFBFC,#F4F3EE" style=“height: 600px;
                        width: 100%; text-align: left;”>
                       


                       

                       

                       

                       

                       

                       

                       

                       

                       

                       

                       

                       

                       

                       

                       

                       

                       

                   

Just use
<div id=“MainTabbar” enableforcehiding=“true”  tabstyle=“silver” …
