从网上下的,稍微改进了一下,做成控件形式,给各位有需要的朋友,其中有很多不完善之处,且只能在IE下使用.

在页面里应用:

<%@ Register TagPrefix="cc1" Namespace="LongYu.Utility" Assembly="LongYu.Utility" %>
<cc1:TaskPanelBar id="MyTaskPanelBar" runat="server" BaseDir="webparts"></cc1:TaskPanelBar>

<%@ Register TagPrefix="webparts" Namespace="Hszw.Utility" Assembly="Hszw.Utility" %> 后台代码示例:

        protected LongYu.Utility.TaskPanelBar MyTaskPanelBar;
    
        private void Page_Load(object sender, System.EventArgs e)
        {
            for (int i=0;i<4;i++)
            {
                MyTaskPanelBar.AddParentNode("标题");
                MyTaskPanelBar.AddChildNode("内容","我是内容0","http://www.hszw.com");
                MyTaskPanelBar.AddChildNode("内容1","我是内容1","http://www.hszw.com");
                MyTaskPanelBar.EndParentNode();
            }

        }
