动态更改SiteMapNode的颜色

Question

我想在运行时动态更改SiteMapNode的颜色。

我要从母版页更改它。

代码的某些部分是这样的：

  

C1.Web.Command.C1WebMenuItem item = new   C1.Web.Command.C1WebMenuItem（）;           C1.Web.Command.C1WebMenuItem subitem = new C1.Web.Command.C1WebMenuItem（）;           C1.Web.Command.C1WebMenuItem msgitem = new C1.Web.Command.C1WebMenuItem（）;           C1.Web.Command.C1WebItemCollection collection = C1WebMenu1.Items;

    if (collection.Count > 0)
    {
        item = (C1WebMenuItem)C1WebMenu1.Items[0];
        item.CreateChildGroup();
        msgitem = (C1WebMenuItem)C1WebMenu1.Items[13];
        msgitem.Text = msgitem.Text + "(1)";
        ----------------- i want to change the color of msgitem.text------------
        if (Session["intUserId"] != null)
        {





            dsAccessed = objSASiteMaster.smaSPGetLastAccessedCases(Session["intUserId"].ToString());
            if (dsAccessed.Tables.Count > 0)
            {
                if (dsAccessed.Tables[0].Rows.Count > 0)
                {
                    for (int i = 0; i < dsAccessed.Tables[0].Rows.Count; i++)
                    {
                        DataSet dsCase = objSASiteMaster.GetCaseByCaseID(dsAccessed.Tables[0].Rows[i]["lacnCaseID"].ToString());

                        using (DataTable dtCase = dsCase.Tables[0])
                        {
                            if (dtCase.Rows[0]["GroupID"].ToString() == "149")
