You do know that it's possible to export to csv format from within the records viewer right? Or isn't that an option in your case?

Hi Tim,

yes, i know that it is possible to export to csv from the recordviewer. But because the two formulars have so many fields (about 200 for the one and about 300 for the other form ) the formviewer can't load entries into the recordviewer. And if i use the icon in the top of the interface, i can't select single records, but get all of them.

But i would like to continue to use the extra admin-interface functions that i am creating, because it gives me the option to select single records, and also to delete records.

Do you have any comments/suggestions to my posted code? And maybe you can spot any errors that i am making?

Hi Christian, were you able to resolve this? I'm dealing with a similar issue.

Hi Amir.

No, i did not manage to use the contour backend in Umbraco to export data

is working on a reply...
