  1.   

    咋都是js脚本呀，有没有做过C#脚本的啊？
      

  2.   

    TreeNodeCheckChanged 事件怎么不起作用 :
     <script language="javascript">
    <!--
                    function postBackByObject() {
                        var o = window.event.srcElement;
                        if (o.tagName == "INPUT" && o.type == "checkbox") {
                            event.srcElement.nextSibling.click(); ;
                        }
                    }
    -->
    page_load:
                    this.tvRight.Attributes.Add("onclick", "postBackByObject()");
    1、选择父接点的复选框时   子接点的复选框全部选中   
    2、取消父接点的复选框时   子接点的复选框全部取消
