各位高人再问一个关于treeview里的checkbox的问题~

Question

protected void Page_Load(object sender, EventArgs e)
        {
            
            this.Label1.Text = "";
            this.lbl_ShowErr.Text = "";
            //绑定所有的用户
            //this.UserRightTree.Attributes.Add("onclick", "doCheck()");
            if(!IsPostBack)
            {
            int outrow=0;
            DataSet ds = Y10.BLL.Admin.SystemManager.SystemUserManager_BLL.GetUserList(1, 1000, out outrow);
            dropdownlist1.DataSource = ds.Tables[0];
            dropdownlist1.DataTextField = "realname";
            dropdownlist1.DataValueField = "adminid";
            dropdownlist1.DataBind();
            
            //根据用户权限绑定目录树
            SubBaseIniTreeView(Convert.ToInt32(dropdownlist1.SelectedValue));
            
            }
        }
