如何从Repeater Control中的公共功能访问面板ID

Question

I need to show list of years for which i have Photo albums. I use Repeater control for this and wrapper year inside a div control. I also pass current Year as QueryString . I need to show the current year in red as a background for div. my panel always return null as i am not able to pass the Object Sender, RepeaterItemEventArgs e . How can i alter this code so that i can change the CssClass from code behind.

I can use another approach for same by using Literal Control & show my list of Years as List <ul> ... which i can use & have full control over my list css.

Please advice how i can achieve this in best & effective way. I am also keep to get in done in the way i am trying to do it as it might be useful in future & very education for me

RESOLVED ISSUE by using following code

protected void rptAlbumsYears_ItemBound(Object Sender, RepeaterItemEventArgs e)
{
    try
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            DataRowView drv = (DataRowView)e.Item.DataItem;
            int Year = Convert.ToInt32(drv["Year"]);
            Repeater Repeater2 = (Repeater)e.Item.FindControl("rptAlbumsYears");
            Panel pnlYear = (Panel)e.Item.FindControl("pnlYear");
            int CurYear = 0;
            CurYear = int.Parse(Request["Year"].ToString());
            if (CurYear == Year)
            {
                pnlYear.CssClass = "AlbumPageYearListingCurrent";
            }
        }
    }
    catch (Exception ex)
    {
        throw;
    }
}
