Hi Bob, First of all have a look to these lessons: http://lessons.runrev.com/spaces/lessons/manuals/datagrid/lessons/7313-How-Do-I-Get-Data-Associated-With-a-Row-or-Column- and to the SetDataOfIndex and SetDataOfLine commands, in the API documentation > ps. Thanks Zryip for all the help, but it appears your methods call things in > the parent script that I cannot see or access (that may be a good thing) and > so I cannot see what they are doing and why. I need to see code happen to > understand it. I planned to create a new step by step tutorial about drag & drop technics in datagrids. A kind of compilation of all the experiments I done on this subject but this time with details explanation. Will write it at soon as I have more time for. Best regards, -- -Zryip TheSlug- wish you the best! 8) http://www.aslugontheroad.co.cc _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
