ListView Exporting/Importing data

I would like to make a Export / Import buttons that will save/open files that contain listView data (ListView Items)

Can someone tell me is there a way to do this?

Yes, of course there's a way to do that. It's pretty straightforward in that you open the file and then read or write the data. However, it does depend somewhat on the format you want for the file.

Can I use a custom made format, or I need to use something like .xml

[deceptikon]

You can use whatever format you want.

Isn't the write and read stuff for text only?
just curius how it's going to work out, or I have to use a custom/special code so it saves it as list with details and not like text (that would be weird...)

[deceptikon]

To write the file you'll loop through the items and save them to a text file (or a binary file if you so choose). There's a conversion involved to produce the file format you want.

To read the file you'll parse it, convert each record back to something that can be applied to a ListView item, apply it, and repeat for each record until the file is exhausted.

I get the impression that you think there will be a one line solution that magically converts a file to a ListView, which itself would require a bit of scaffolding that you'd have to write as well, if you want it.

Not that I understood you clearly, but I made it somehow... :D
