Treeview TAG

I'm using the XTreme SuitePro ActiveX 2009 Vol4 (13.4.0) with Vb.NET. I tried to store additional data in the TAG-field of a treeview node like in this example:

Structure testSTRUCT
        Dim numb As Integer
        Dim pics As Boolean
End Structure

Private Sub StoreDataToNode
        Dim tvnode As TreeViewNode
        Dim nodeData As testSTRUCT = New testSTRUCT

        nodeData.numb = 13123
        nodeData.pics = False
        tvnode = tvDemo.Nodes.Add(, , "F_1", "first node")
        tvnode.Tag = nodeData
End Sub
Private Sub Form1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Click
    StoreDataToNode()
End Sub

Running the program the debugger stops in the row "tvnode.Tag = nodeData"
But i got the error "Der Wert liegt außerhalb des erwarteten Bereichs" (e.g. in english "The value is outside the expected range") in the line "tvnode.Tag = nodeData" after  starting the program an clicking on the form.

However if i only store an integer in the tag-field of my treeview node (like this: tvnode.Tag = 1), the programm run through the line above without any error.

How can i store my additional data in the tag field?

Hi,

thanks for your reply. I'm a bit confused. The same way of proceeding to store additional data with VB-NET-structure in the tag-field operates in many different controls like microsoft treeview, microsoft listview, all purecomponents-controls, etc. without problems.

But for my software i need markups, so i have to use the codejock treeview not the microsoft one that doesn't support markups.

Perhaps i have to try your suggestion or i will do it with an collection to link the treeview node with the right collection item.
