这个例子用datalist实现主从关系数据的现实，如果还有细节不符合要求，请联系mailto:[email protected]

我的意思是在父节点的datalist中嵌套一个子节点的相关信息，而不是你的点父节点然后在另外一个独立的datalist中显示子节点的信息。就是hbxtx(xy) 所说的那种意思，请大家不吝赐教啊！！！！

说明：1——
上面的代码使用了REPEATER，同DATALIST类似。2——
这个代码中，我在对LM（相当于你的CHANEL）菜单进行绑定后，读取LM的数量，然后通过LM的Items[i]来FindControl(XM)，这里XM相当于你的lanmu，XM是你在CHANEL中放置的DATALIST的ID，然后再绑定数据。
你可以把这部分代码放到CHANEL的ITEMDATABOUND事件中进行处理，这样就不用获取CHANEL的数量了。
