    For version 2010.2.826.40. I have set a radlistbox so it will alternate every other row background with a different color.  Doing that caused the side effect that the mouse over color doesn't change as would be the case in the list box's default behavior.

    protected void Load_ManualWithFoundContent(string SearchResult)
                WebServiceProxy wsp = new WebServiceProxy();
                DataSet ManualsWithSearchResults = wsp.GetServicesHandle.Search_ManualTitlesResult(SearchResult);
                DataTable dt = ManualsWithSearchResults.Tables[0];
                DataRowCollection drc = dt.Rows;
                RadListBoxItemCollection rlbic = RadList_ManualsWithFoundContent.Items;
                int i = 0;
                foreach (DataRow dr in drc)
                    RadListBoxItem rlbi = new RadListBoxItem(dr["ManualName"].ToString(), dr["pKey"].ToString());
                    rlbi.BackColor = i++ %2 ==0 ? Color.WhiteSmoke : Color.White;

    My thought on this is I need to add a handler client side for mouse over?
    function RadList_ManualsWithFoundContent_OnClientMouseOver(sender, evenArgs) {
      ...???set item color???...   
    Not sure how to do this (looking through client side api).

    Thanks in advance

    Hello John,

    Actually there is a simpler solution to this issue - instead setting BackColor property of the items, please set CssClass property:

    rlbi.CssClass = i % 2 == 0 ? "whiteSmoke" : "white";

    and add the following css styles to the page:

    <style type="text/css">
      .RadListBox  .whiteSmoke
          background-color: WhiteSmoke;
      .RadListBox  .white
          background-color: White;

    this way the hover style will no be overwritten.
    I've attached my test page for a reference.
