ASP.NET 实现点击左侧菜单，实现将相应的值传给另一个aspx文件

我的程序是基于DWZ框架做的 ，左侧菜单是在后台中拼接的，我想在onclick事件中实现传值，有人知道怎么做吗？另外我想弱弱的问一下，onclick事件只能执行脚本函数吗？不能执行后台定义的函数吗？
部分菜单拼接代码如下：
StringBuilder LeftList = new StringBuilder();
if (FourthTable.Rows.Count != 0)
                                                    {
                                                        for (int m = 0; m < FourthTable.Rows.Count; m++)
                                                        {
                                                            LeftList.Append("<ul>");
                                                            LeftList.Append("<li><a href=\"fourth.aspx\" onclick=这里有问题 target=\"navTab\" rel=\"\">" + FourthTable.Rows[m]["名称"] + "</a></li>");                                                           
                                                            LeftList.Append("</ul>");                                                                              
                                                        }
                                                    }
