根据筛选条件不同形成不同的树

比如：

    e.Form.Controls("TreeView2").BuildTree("窗口客户跟进_tbl_genjin", "A|B|C") 

   或者e.Form.Controls("TreeView2").BuildTree("窗口客户跟进_tbl_genjin", "A|D|C") 

afterchecknode
Dim nms As String() = {"A,"B","C"} '指定生成目录树的各列

如何实现

afterchecknode 里更改成对应的Dim nms As String() = {"A,"B","C"} '指定生成目录树的各列

即当  e.Form.Controls("TreeView2").BuildTree("窗口客户跟进_tbl_genjin", "A|B|C") 

这个{"A,"B","C"} 附值给变量给如何解决的问题 {}里面的内容如何赋值

dim a string ="A,"B","C"

Dim s String ==""""track_user"""" & "," & """"dianxin_track_zhuangtai"""" &  "," & """" next_time & """"

这个也不对，谁给解决一下
