我有2个gridview控件，其中一个gridview控件添加了如下代码

        protected void gvPagePartConfig_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            switch (e.Row.RowType)
            {
                case DataControlRowType.Header:
                    e.Row.BackColor = System.Drawing.Color.White;
                    break;
                case DataControlRowType.DataRow:                   
                    string strID = e.Row.Cells[1].Text.Trim();
                    if (Convert.ToInt32(ViewState["LineNo"]) == 0)   //如果是奇数行
                    {
                        e.Row.Attributes.Add("onMouseOut", "SetOldColor(this);");
                        e.Row.Attributes.Add("onMouseOver", "SetNewColor(this);");
                        e.Row.Attributes.Add("onKeyOut", "SetOldColor(this);");
                        e.Row.Attributes.Add("onKeyOver", "this.style.background='#C0C0FF'");
                        ViewState["LineNo"] = 1;
