安装方法:(也可参照Readme.txt)
1.bulid.将bulid.bat的路径指向csc.exe所在路径,生成Microsoft.Web.UI.WebControls.dll。
2.在wwwroot下创建空目录webctrl_client\1_0。
3.将build\Runtime下的文件拷至webctrl_client\1_0下。
4.选择工具箱的自定义工具箱，添加Microsoft.Web.UI.WebControls.dll。
树的建立


　　具体方法是：创建一个数据库，设计树图信息表TREE_INFO，包含NODEID、PARENTID、NODENAME、ADDERSS、ICON字段，其它字段根据实际业务而定，节点名称NODENAME将在树型控件的节点上显示，NODEID字段保存节点的唯一标识号，PARENTID表示当前节点的父节点号，标识号组成了一个“链表”，记录了树上节点的结构。设计一个Web窗体其上放置TreeView控件。



Private Sub CreateDataSet()’建立数据集
Dim myConn As New SqlConnection()
Dim myCmd As New SqlCommand("select NODEID,NODENAME,PARENTID,ADDRESS,ICON from Tree_info", myConn)
Dim myDataAdapter As New SqlDataAdapter()
myConn.ConnectionString = Application("connectstring")
myCmd.CommandText = ""
myCmd.Connection = myConn
myDataAdapter.SelectCommand = myCmd
myDataAdapter.Fill(ds, "tree")
End Sub


　　建树的基本思路是：从根节点开始递归调用显示子树


Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
CreateDataSet()
intiTree(TreeView1.Nodes, 0)
End Sub
Private Sub intiTree(ByRef Nds As TreeNodeCollection, ByVal parentId As Integer)
Dim dv As New DataView()
Dim drv As DataRowView
Dim tmpNd As TreeNode
Dim intId As Integer
dv.Table = ds.Tables("tree")
dv.RowFilter = "PARENTID=’" & parentId & "’"
For Each drv In dv
tmpNd = New TreeNode()
strId = drv("NODE_ID")
tmpNd.ID = strId
tmpNd.Text = drv("NODE_NAME ")
tmpNd.ImageUrl = drv("ICON").ToString
Nds.Add(tmpNd)
intiTree(Nds(Nds.Count - 1).Nodes, intId)
Next
End Sub

在 selectedindex 事件中

Response.Write("<script>window.open('你要显示的页面','main')</script>");

设置节点的target属性为你的frame就可以了
