需求如下:现在要实现TreeView勾选某一个父结点的复选框后,其下所有级的所有子结点都被勾选中,如果该父结点下所有级的所有子结点都被勾选中后该父结点也被勾选中,但如果有没有勾选的话该父结点也不会被勾选上.功能没实现完,请给出完整代码,谢谢

没有单独列出，觉得麻烦。
LZ就看自己有用的部分，这是做的权限设置.
和楼主的要求非常吻合。
父类采用的DataList绑定，子类采用的是Repeater绑定。

如果该父结点下所有级的所有子结点都被勾选中后该父结点也被勾选中,但如果有没有勾选的话该父结点也不会被勾选上。
红色部分需要用的数据库，根据具体情况自己设计。

对CheckBox进行了重写，就是加一个Text属性。
