TreeNode的NavigateURL会跳转到新页面，怎样屏蔽

夜冰

我是这样处理的,在数据库中建了一个菜单表,表中菜单的地址与nodeid相关链,根据它查找相对应的地址,代码就是下面的.
Dim tabID As String = e.Node.NodeID
        Dim sql As String = "select url from 菜单 where 菜单id='" & tabID & "'"
        Dim url As String = hr.ExecuteOneSQL(sql)
        Dim tabTitle As String = e.Node.Text
        Dim icons As String = e.Node.Icon
        If url = "" Then url = "../zclr/F_addzc.aspx"
        PageContext.RegisterStartupScript(TB_R1.GetAddTabReference(tabID, url, tabTitle, IconHelper.GetIconUrl(icons), True))
