Expanding a TreeNode without selecting the Node in a Treeview

Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick

    If e.Node.IsSelected Then
         '...
    End If 
End Sub

Issues
Current issues with NodeMouseClick:

• NodeMouseClick event does not fire
• Moving with your keyboard selecting an event does not fire NodeMouseClick

In this case you better use the AfterSelect event: 

Private Sub TreeView1_AfterSelect(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterSelect

     If e.Node.IsSelected Then
         '...
    End If 
End Sub
