keeping a treeview from expanding
I have a treeview that has three parent nodes, each having a multiple child nodes. I'm selecting various child nodes (single select), adding it's corresponding data, via ADO, to a listview, then removing the selected treeview node.
My question is this. Once I've started to make my selections from a group of child nodes, I need to somehow keep the user from changing the parent nodes (thus, keeping the user from mixing data). Is there a way to disable the treeview's ability to expand & collapse nodes using the count method of my listview?
Thanks,
Mark

Hi
One solution would be to have an object declared at the top of your form:
Private mobjParentNode As Node
In the event where the parent node is selected set it:
e.g.
Private Sub tvwTreeView_MouseDown(Button As Integer, Shift As Integer, x As Single, y As Single)
Dim objNode As Node
Set objNode = tvwTreeView.HitTest(x, y)
If objNode Is Nothing Then
Exit Sub
End If
Set mobjParentNode = objNode
End Sub
then, when you need to, set the desired node to be the mobjParentNode:
Set tvwTreeView.SelectedItem = mobjParentNode
hope it helps
