TreeView增加滚动条，请帮忙看看。

代码如下，很简单的，我就是想让该TreeView在显示在左面，并且当都展开时，进过一定高度就出现滚动条。我试了半天也不好用。<%@ Page Language="C#" AutoEventWireup="true" CodeFile="wfm_DOC001_02.aspx.cs" Inherits="DocManager_wfm_DOC001_02" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

  1.   

    我调试了一下,将另外将
    <div style="OVERFLOW: auto; WIDTH: 100%; HEIGHT: 10px"> 
                             <table cellpadding="1" cellspacing="1" width="100%" border="1"> 
                             <tr> 
                             <td> 
                             <asp:TreeView ID="trvForderList" Style="position: absolute; top: 16px" runat="server" 
                                ShowLines="True" OnTreeNodePopulate="trvForderList_TreeNodePopulate"> 
                             </asp:TreeView> 
                             </td> 
                             </tr> 
                             </table> 
                         </div> 改为:<div style="OVERFLOW: auto; WIDTH: 100%; HEIGHT: 10px"> 
    <asp:TreeView ID="trvForderList" runat="server"  ShowLines="True" OnTreeNodePopulate="trvForderList_TreeNodePopulate"> 
          </asp:TreeView> 
     </div> 即可,你试一下, 有问题加QQ 343397317交流

    楼上的兄弟，可能刚才我没说清楚，我上面贴的这个页是在前一个HTM页中写脚本弹出来的页，全屏的，不知道是否有关系。在编辑状态下我也能看到滚动条，可是一运行起来就不行了，没有显示出滚动条，并且TreeView并没有显示在我写的那个Table中。它象一个层一样浮在最上面。

    嗯, [email protected],或者直接加QQ 说,比较快一些
      

  4.   

    布局有点乱, 不过我想到了一个办法解决这个问题, 将左边的网页用iframe嵌入就可以实现, 你试一下
      

  5.   

    也就是说把TreeView部分做成一个网页, 再将
    <div style="OVERFLOW: auto; WIDTH: 100%; HEIGHT: 10px">   
                              <table cellpadding="1" cellspacing="1" width="100%" border="1">   
                              <tr>   
                              <td>   
                              <asp:TreeView ID="trvForderList" Style="position: absolute; top: 16px" runat="server"  
                                ShowLines="True" OnTreeNodePopulate="trvForderList_TreeNodePopulate">   
                              </asp:TreeView>   
                              </td>   
                              </tr>   
                              </table>   
                          </div>   修改为:<iframe width="你要的宽度" height="你要的高度" src="TreeView网页地址"></iframe>
      

  6.   

    将treeview放在iframe中，然后再用div设定或设定iframe。
