您可以设置treeview子节点的CSSClass

      <asp:TreeView LeafNodeStyle-CssClass="childnode" runat="server">....</asp:TreeView>

然后使用jquery你得到类并设置return false,如下所示.

      $(".childnode").click(function(){
                 return false;
      })

...同样的方法你可以设置RootNodeStyle-CssClass,ParentNodeStyle-CssClass类并使用jquery来设置它们......
