分享关于treeview中checkbox的问题~``急~~~~~~~~~~~~~~~~~~~~~~
我把treeview1控件中的showcheckboxes=all
如何做到选中选中父节点时该父节点下所有子节点全部选中.选中一个子节点,该子节点的父节点被选中?
我是用这个方法把treeview和数据库绑定的
<script runat="server">
Const connectionString As String = _
"Server=localhost;Integrated Security=True;Database=znh"
Sub Page_Load()
If Not IsPostBack Then
PopulateNodes()
End If
End Sub
Sub PopulateNodes()
Dim dst As DataSet = GetTreeViewData()
For Each masterRow As DataRow In dst.Tables("mainmenu").Rows
Dim masterNode As New TreeNode(masterRow("menu").ToString())
TreeView1.Nodes.Add(masterNode)
For Each childRow As DataRow In masterRow.GetChildRows("Children")
Dim childNode As New TreeNode(childRow("childmenu").ToString())
masterNode.ChildNodes.Add(childNode)
Next
Next
End Sub
Function GetTreeViewData() As DataSet
Dim con As SqlConnection = new SqlConnection(connectionString)
Dim dadCats As SqlDataAdapter = New _
SqlDataAdapter("SELECT * FROM mainmenu", con)
Dim dadProducts As SqlDataAdapter = New _
SqlDataAdapter("SELECT * FROM childmenu", con)
Dim dst As DataSet = new DataSet()
dadCats.Fill(dst, "mainmenu")
dadProducts.Fill(dst, "childmenu")
dst.Relations.Add("Children", _
dst.Tables("mainmenu").Columns("menu_id"), _
dst.Tables("childmenu").Columns("menu_id"))
return dst
End Function
Sub check(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.TreeNodeEventArgs)
End Sub
</script>
<html>
<head>
<title>Master/Detail TreeView</title>
</head>
<body>
<form id="form1" runat="server">
<asp:TreeView
ID="TreeView1"
Runat="Server" ShowLines="True" ShowCheckBoxes="All" />
</form>
</body>
</html>
下面我该怎么写,选中选中父节点时该父节点下所有子节点全部选中.选中一个子节点,该子节点的父节点被选中?

写2个函数，用节点做参数：
1. 选中父节点，递归调用将子节点选中。
2. 选中子节点，递归调用将父节点选中。
然后在点击事件中，调用这两个方法。
