怎样改为从数据库读入数据来实现树型表示啊？（假设ACCESS 数据库。文件名db1.mdb）求救。。。急！

简单说就是绑定数据库Top

打开控制面板中的ODBC图标，点击System DNS标签，依次选择Add>Microsoft Access，并点击Finish按钮。在拉下来的对话框中输入数据源的名字，比如是mymdb，然后创建数据源，双击OK按钮。
我是这样绑定的。可是编译是说USING SYSTEM.DATA.ADO 出问题啊。

从数据库生成树：
public void InitTree(Microsoft.Web.UI.WebControls.TreeNodeCollection Nds,string parentId,DataSet ds,string TableName)
{
dv=new DataView();
Microsoft.Web.UI.WebControls.TreeNode tmpNd;
string intId;
dv.Table=ds.Tables[TableName];
dv.RowFilter="ParentId=" + parentId ;
foreach(DataRowView drv in dv)
{
tmpNd=new Microsoft.Web.UI.WebControls.TreeNode();
tmpNd.ID=drv[0].ToString();
tmpNd.Text=drv[2].ToString();
Nds.Add(tmpNd);
intId=drv[1].ToString();
InitTree(tmpNd.Nodes,tmpNd.ID.ToString(),ds,TableName);
}
}
表：
id parentid name
要先在函数外面定义一个DataView dv
