I'm in the following scenario: I have a single custom list coupled with a document library (for the 'attachments'). Search on this list and the attachments is done by FAST Search. All search results should be shown in a gridview, showing part of the columns of my custom list. To make things more complex, I would like to edit the existing SharePoint listitems in this gridview, like you would edit them in Datasheet View.
Is there any control (builtin or 3rd party) that makes this possible?
EDIT: inline editing is a must, we can't use the EditForm.
