I am not sure that you can assume that the indexes always going to correspond to the display order. This is why I decided to use dgIndex function as it returns the indexes in the display order. I do plan on having multiple sorting options.
This still does not explain why I am not getting any results at all using the dgIndex function. Could this be a platform issue if my syntax is correct? I am using Windows XP. -= Mike -----Original Message----- From: use-livecode-boun...@lists.runrev.com [mailto:use-livecode-boun...@lists.runrev.com] On Behalf Of zryip theSlug Sent: Wednesday, October 19, 2011 5:44 PM To: How to use LiveCode Subject: Re: Resizable DataGrid Question On Wed, Oct 19, 2011 at 10:56 PM, Mike Doub <m...@doub.com> wrote: > I believe that I have found a way to get the previous grid item, but I > must have the syntax incorrect for getting the dgIndex of me. > Nothing is being returned.

However, if you allow me, you could have done this with less code: on FillInData pDataArray put pDataArray["LastName"] & \ comma & space & pDataArray["FirstName"] & space & pDataArray["MiddleName"] into tCurrentName set the text of field "Name" of me to tCurrentName put the dgIndex of me into tTheIndex put (the dgIndex of me - 1) into tThePreviousIndex if (tThePreviousIndex > 0) then put GetDataOfIndex(tThePreviousIndex, "LastName") into tPreviousName end if if ((first char of tCurrentName is not first char of tPreviousName) or (tThePreviousIndex is 0)) then set the visible of group "spacer" of me to true else set the visible of group "spacer" of me to false end if end FillInData Best regards, -- -Zryip TheSlug- wish you the best! 8) http://www.aslugontheroad.com _______________________________________________ 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 _______________________________________________ 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
