根据数据库，动态显示treeview

数据库如下：
id name parent（父节点） src（节点的链接地址） zt（该节点是否可以用，1为可用）

以上是我的数据库设计，请问告示，如何根据zt这个数据列，来动态生成treeview呢？？
麻烦给出详细的c＃代码，在此先谢了！

其实如果是用c#做，就很简单，你如果真的是会c#的话，想想就可以了。
但如果是用js做....那样就真是件难事了，难难难，但做出来的效果却是好好的。
又如果是用js+xml做的话，就不难了...而且效果也好好，所以我建议呢，不要用数据库存结点记录，而用xml来存

那如果用xml做的话,应该如何呢?因为我的设计初衷是想通过一个页面来进行权限管理的,难道改一次权限管理就生成一个xml文件??
可以举个例子吗??
改一次权限就修改一次XML不是生成一个新的
