  problem using findnode method of the treeview

  Feb 28, 2007 01:40 PM|LINK

  Hello,

  I am using findnode method to find a node in the treeview but its returning nothing. Can anyone please go through the code below and tell where where I am getting error.

  Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

  'Dim contactIDReader As MySqlDataReader

  Dim contactNameReader As MySqlDataReader

  Dim groupContacts As New ArrayList

  Dim index As New Integer

  If Not Page.IsPostBack Then

  Dim groupNode As New TreeNode

  Dim otherNode As New TreeNode

  groupNode.Text = "Groups"

  otherNode.Text = "Others"

  treeContacts.Nodes.Add(groupNode)

  treeContacts.Nodes.Add(otherNode)

  _commandString = String.Format("select GroupID,GroupName from jukebox.group where UserID={0}", Session("SessionUserID"))

  _myDataReader = ManageDB.GetDataReader(_commandString)

  While _myDataReader.Read

  treeContacts.FindNode("Groups").ChildNodes.Add(New TreeNode(_myDataReader(1).ToString, _myDataReader(0).ToString))

  _commandString = String.Format("select a.ContactID,a.FirstName from jukebox.contacts a,jukebox.groupdetails b where a.ContactID=b.ContactID and GroupID={0}", _myDataReader(0).ToString)

  contactNameReader = ManageDB.GetDataReader(_commandString)

  While contactNameReader.Read

  treeContacts.FindNode("Groups/" & _myDataReader(1).ChildNodes.Add(New TreeNode(contactNameReader(1).ToString, contactNameReader(0).ToString))

  End While

  contactNameReader.Close()

  End While

  _myDataReader.Close()

  End If

  End Sub
