在C#中创建DIV并向其添加控件

Question

我有以下内容在c#的asp页面上添加了一个布局

chart_holder.Controls.Add(new LiteralControl("<div id='chart_location"+ i.ToString()+"'>" +
                        "<asp:Panel ID='chartbtns"+i.ToString() +
                   "'runat='server' Visible='true' >" +
                         "<div class='chart_button_container'>" +
                            "<div class='chart_buttons'> " +
                               "<ul class='menu2' >" +
                                   "<li> <a href='#' class='chart_buttons_image_save' title='Save'></a>" +
                                        "<ul><li> <asp:LinkButton ID='btnSaveXLSX" + i.ToString() + "' runat='server' oncommand='btnSaveXLSX_Click' CommandArgument='"+ i.ToString() +"' >Excel</asp:LinkButton></li> " +
                                        "<li> <asp:LinkButton ID='SavePDF" + i.ToString() + "' runat='server' oncommand='btnSavePDF_Click' CommandArgument='" + i.ToString() + "'>PDF</asp:LinkButton></li>" +
                                            "<li><asp:LinkButton ID='btnSaveimg" + i.ToString() + "' runat='server' oncommand='btnSaveimg_Click' CommandArgument='" + i.ToString() + "'>Image</asp:LinkButton> </li>" +
                                       " </ul>" +
                                    "</li>" +
                                "</ul>" +
                            "</div>" +
                            "<div class='chart_buttons'>" +
                                "<asp:LinkButton ID='enlarge_chart_" + i.ToString() + "'CssClass='chart_buttons_image_enlarge' style='background-image:url(/Images/1386870554_arrow-maximise.png)' Runat='server' oncommand='enlarge_chart_Click' CommandArgument='" + i.ToString() + "'></asp:LinkButton>" +
                            "</div>" +
                            "<div class='chart_buttons'>" +
                                "<asp:LinkButton ID='refresh_chart_" + i.ToString() + "' CssClass='chart_buttons_image_refresh' style='background-image:url(/Images/refresh.png)' Runat='server' CommandArgument='1'></asp:LinkButton>" +
                            "</div>" +
                       " </div>" +
                       "<div id ='chart" + i.ToString() + "_holder" +"' enableviewstate='true' runat='server' style='height:95%; width:100%'> </div>" +

                       "</asp:Panel>" +
                    "</div>"));

然后我想最终在上面的一个div中添加一个图表.无论如何我可以访问div然后添加一个控件...？

以前我有以下

chart1_holder.Controls.Add(chart_location_1);

但是chart1_holder来自asp页面,而不是动态的.

使用这个:

 System.Web.UI.HtmlControls.HtmlGenericControl createDiv =
        new System.Web.UI.HtmlControls.HtmlGenericControl("DIV");      
        createDiv.ID = "createDiv";
        createDiv.InnerHtml = " I'm a div, from code behind ";
        this.Controls.Add(createDiv);
