detect mouse event on node of a treeview

[Sam]

Hi,
I'd like to get the selected node when the user select a node in my
treeview. I know how to get the selected node, what I don't know is how
to detect that the user has selected a new node.

What methods should I use ?
thx

I basically used a static variable to keep the old value of the
selected node and check to see if the new selected node was the same as
the old node. If not then I know they selected a new node.

Private Sub TreeView1_AfterSelect( _
ByVal sender As Object, _
ByVal e As TreeViewEventArgs :
) Handles TreeView1.AfterSelect
Static LastNode As TreeNode
Dim CurrentNode As TreeNode = _
Me.TreeView1.GetNodeAt(Me.TreeView1.PointToClient(Cursor.Position))
If Not CurrentNode Is LastNode Then
LastNode = CurrentNode
If Not CurrentNode Is Nothing Then
MsgBox(CurrentNode.Text)
Else
MsgBox("No node selected!")
End If
End If
End Sub

thanks to both of you
finally here is what i've done

Private Sub tvRelations_AfterSelect(ByVal sender As System.Object,
ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles
tvRelations.AfterSelect

If tvRelations.SelectedNode.Nodes.Count = 0 Then
txtTable1.Text = tvRelations.SelectedNode.Parent.ToString
txtTable2.Text = tvRelations.SelectedNode.ToString
End If
End Sub
