Treeview control

[christophe]

Hi,

I'm new to using the Treeview control, part of the Windows Common Controls that you find in Project/Components.

When I add the Treeview control to my form I see 'Sample node' with Windows Explorer like indents, in the control in Design time. But when I run the program, there's no text in the control at all. Could someone tell me how I can make the text appear in run-time, and how I can edit the text?

Thanks!

Sure! In disign time it just shows you how the control looks like, but it is up to you to populate the control.
Here is an example:



Dim xParent As Node 'Parent Node
Dim xChild As Node 'Child Node
Dim i As Integer 'Counter for parent Nodes
Dim j As Integer 'Counter for Child nodes

With TreeView1
.LineStyle = tvwRootLines
.Indentation = 300
For i = 1 To 5
Set xParent = .Nodes.Add(, , "Parent" & i, "Parent" & i)
For j = 1 To 10
Set xChild = .Nodes.Add(xParent, tvwChild, , "Child" & i & " to node " & xParent.Text)
Next
Next
End With




Look in the MSDN library for Node object. It will tell you what it is and how to work with it.

Thanks for the reply, Serge.

But I cut and paste the code you give me, and in run-time, I still can't see anything. I didn't change any properties - am I supposed to?

Here's my exact code:

Dim xParent As Node 'Parent Node
Dim xChild As Node 'Child Node
Dim i As Integer 'Counter for parent Nodes
Dim j As Integer 'Counter for Child nodes



Private Sub TreeView1_BeforeLabelEdit(Cancel As Integer)
With TreeView1
.LineStyle = tvwRootLines
.Indentation = 300
For i = 1 To 5
Set xParent = .Nodes.Add(, , "Parent" & i, "Parent" & i)
For j = 1 To 10
Set xChild = .Nodes.Add(xParent, tvwChild, , "Child" & i & " to node " & xParent.Text)
Next
Next
End With
End Sub

Am I doing something wrong?

You pasted to the wrong event. Change it to Form_Load event.
