I'd like to make a web part which contains Document Datasource and binded to it Basic Repeater. Web part should allows user to select documents (for example Page (menu items)) and add these documents to Document Datasource. I don't know if it is possible using standard form controls but if it's not I'd like to know is it possible to take document using it's path and add it to datasource and then take another document using it's path and add it to datasource and so on?
