Use Unbound Grid to Display External Data

I have a user-defined table that I use to maintain information about documents (mostly cad drawings and pdf’s of cad drawings) I have a dashboard that helps locate the documents and can display them. I want to be able to add new documents to the table by selecting files from a folder. I want to present the files to “import” by displaying them in a gird. I have customization that allows the user to enter a folder and then shows a list of files in a text box. I would like it to be in a grid to make it easier to select individual rows. I cannot find an easy way to simply populate a grid that is not bound to a table or data view. Any suggestions would be appreciated.
