Hi everyone

I 'm Using the class from this example

Using Serialization to Persist TreeView Control (VB.NET)[^]

to populate a treeview from a xml file and then save it once again
I can add, remove treenodes and save them to the xml file.

But what I want to do and don't know how is that:

- I want the treeview nodes to have a tag property and I want this tag to hold some text
- I want the tag property's text to load in a textbox so I can edit it and save it along with other treenode properties
i tried so many things but none of them worked untile my mind got stuck.
I highly appreciated if someone can show me how it's done or point me to the right direction

When you are populating the treeview create the tag when you add the node...

VB

Dim tn As TreeNode
tn = treeView.Nodes.Add(Me.Nodes(i).ToTreeNode)
tn.Tag = i 'Whatever it is that you want in the tag

Then read the tag on an appropriate event (e.g. click or afterselect etc)

Me.TextBox1.Text = (e.Node.Tag)

or update it

Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
	If Me.TreeView1.SelectedNode Is Nothing Then
		Exit Sub
	End If
	Me.TreeView1.SelectedNode.Tag = Me.TextBox1.Text
End Sub
