动态生成的菜单的aspx代码为->

the dynamicly generated menu''s aspx code is-->

<div class="set-size"  runat="server">
	
    <div class="categories"  runat="server">
    <ul  runat="server" id="nav">
    <li class="home" style="background-repeat: no-repeat; background-color: #94C23C; background-image: removed(home.jpg); background-removed: center;"><a href="index.htm">Home</a></li>
    <!--Dynamic menu-->
    </ul>
    </div>
	</div>

并且您的cs代码是->

and thye cs code is-->

public void bindmenu()
    {
        HtmlGenericControl li;
        HtmlAnchor link;
        HtmlGenericControl div;

        //for main menu
        DataTable dt = new BALCate().GetCate();
        foreach (DataRow dr in dt.Rows)
        {
            int cateid = int.Parse(dr["cate_id"].ToString());
            String cate_name = dr["cate_name"].ToString();
            li = new HtmlGenericControl("li");
            link = new HtmlAnchor();
            link.InnerText = dr["cate_name"].ToString();
            link.HRef = "CateProducts.aspx?cate_id=" + cateid + "&" + "catename=" + cate_name;
            li.Controls.Add(link);

            //for submenu
            DataTable subcate = new BALCate().GetSubCate(cateid);
            if (subcate.Rows.Count > 0)
            {
                div = new HtmlGenericControl("div");
                div.Attributes.Add("class", "sub-menu column-1");
                HtmlGenericControl sul = new HtmlGenericControl("ul");

                foreach (DataRow sdr in subcate.Rows)
                {
                    int subcateid = int.Parse(sdr["subcate_id"].ToString());
                    String subcatename = sdr["subcate_name"].ToString();
                    HtmlGenericControl sli = new HtmlGenericControl("li");
                    HtmlAnchor slink = new HtmlAnchor();
                    slink.InnerHtml = sdr["subcate_name"].ToString();
                    sli.Controls.Add(slink);
                    slink.HRef = "SubCateProducts.aspx?subcate_id=" + subcateid + "&" + "catename=" + cate_name + "&" + "subcatename=" + subcatename;
                    sul.Controls.Add(sli);

                    DataTable subsubcate = new BALCate().GetSubSubCate(subcateid);
                    if (subsubcate.Rows.Count > 0)
                    {
                        HtmlGenericControl subdiv = new HtmlGenericControl("div");
                        subdiv.Attributes.Add("class", "sub-menu");
                        HtmlGenericControl ssul = new HtmlGenericControl("ul");

                        foreach (DataRow ssdr in subsubcate.Rows)
                        {
                            int subsubcateid = int.Parse(ssdr["subsubcate_id"].ToString());
                            String subsubcatename = ssdr["subsubcate_name"].ToString();
                            HtmlGenericControl ssli = new HtmlGenericControl("li");
                            HtmlAnchor sslink = new HtmlAnchor();
                            sslink.HRef = "SubSubCateProducts.aspx?subsubcate_id=" + subsubcateid + "&" + "catename=" + cate_name + "&" + "subcatename=" + subcatename + "&" + "subsubcatename=" + subsubcatename;
                            sslink.InnerText = ssdr["subsubcate_name"].ToString();
                            ssli.Controls.Add(sslink);
                            ssul.Controls.Add(ssli);
                        }
                        subdiv.Controls.Add(ssul);
                        sli.Controls.Add(subdiv);
                    }
                }
                div.Controls.Add(sul);
                li.Controls.Add(div);
            }
            nav.Controls.Add(li);
        }
    }

实际上，还有一个母版页，其中包含动态菜单"，其中在页面加载时从数据库动态加载数据(类别和子类别).但是问题是每当我单击链接按钮时，菜单都不会从数据库中检索数据，而是显示空白，其中包含其余的静态部分.

actually there is also a master page, which contains DYNAMIC MENU in which data(categories and subcategories) dynamicly loaded from the database at the time of the pageload. but the iissue is that whenever i clicking on the link button , the menu doesnt retrieve the data from the database and appears blank with the remaining static part of it.

推荐答案

尊敬的您尚未为链接按钮添加按钮点击事件.因此，肯定会添加Onclick事件.

Dear you have not added button click event for your link button. So add Onclick event surely it will work.
