Pleas give me example how I can use AskChildrenOrder method. I need to get all child in the same order as current Navigator Order ("Alphanumeric", Alphabetic" etc.) I need get children for all assembly branches, not only top parent, so code should checks whole assembly tree.
In its current state, I doubt that AskChildrenOrder will do what you want. The following link will take you to a problem report and some example code (you might need to log in with your webkey for full access).
Try using the code attached below, it is currently set up to export the assembly navigator to an excel spreadsheet in alphabetical order. You can alter it to export to another platform if you like but the functionality you need is there. Let me know if it works for you. I am currently running TC so there is a chance some changes may need to be made for native users.
