[RESOLVED] Find Treeview node and parent by Tag

[teamster]

I have a treeview which I put a bunch of Category Numbers in as the Tag of the node. Now after having that category number, in another application I wish to search the Category to get the parent text as well as the current selected text. My code looks like this thus far.

        With TreeView1
            For Each node As TreeNode In .Nodes
                If node.Tag = TextBoxCategory.Text Then
                    .SelectedNode = node
                    tbLexicon.Text = .SelectedNode.Parent.Text & " > " & .SelectedNode.Text
                    Exit For
                End If
            Next
        End With

This code came from MSDN, but it never finds my Tag which I know is in it as the other application supplies the values that I am sending back from the same treeview, just copied over to the other app. I have search for hours on this, but the results that I have tried just don't work or have errors that don't correct. For example... A sample of my treeview looks like this...

Air Condition and Heating
.........A/C Compressor & Clutch
..................Tag = 33543
.........A/C Hoses & Fittings
..................Tag = 33544
.........A/C & Heater Controls
..................Tag = 33545

Any help much appreciated.

This is what I use....

Dim gotNode As Boolean = False
    Private Sub selectTreeNode(ByVal parentNode As TreeNode, ByVal nodeID As String)
        If Not gotNode Then
            For Each node As TreeNode In parentNode.Nodes
 
                If node.Tag IsNot Nothing AndAlso node.Tag.ToString = nodeID Then
                    node.TreeView.SelectedNode = node
                    gotNode = True
 
                    Exit Sub
 
                Else
 
                    Call selectTreeNode(node, nodeID)
 
                End If
            Next
        End If
 
    End Sub

and to use it....

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
 
        gotNode = False
        For Each n As TreeNode In Me.TreeView1.Nodes
            If Not gotNode Then
                selectTreeNode(n, "This")
 
            End If
        Next
 
    End Sub

I would not be at all surprised to see someone post a LINQ solution as well.

Thank you. It took me a minute to see what it was doing, but that worked great. Replaced "This" with TextBoxCategory.Text and filled tbLexicon by testing if gotNode was true.
