[Closed] XML usage in UI's

Hi guys.

I have seen a few scripts where the UI’s had a Dotnet component (showing an XML database).
That part of the UI was organized like you would see in excel (basically).

I really want to learn how to do this and was wondering if someone could point me to a good tutorial.
I realize it’s not easy but I do have fair understanding of programming outside maxscript (C#).

I should mention that at this stage I don’t know how to write any information to an XML file, so want info pertaining to both writing and displaying in the UI.

Thanks.
