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. Can any DataGrid experts give me any guidance?
Thanks Mike on FillInData pDataArray set the text of field "Name" of me to pDataArray["LastName"] & \ comma & space & pDataArray["FirstName"] & space & pDataArray["MiddleName"] put char 1 of fld "Name" of me into field "spacerLable" of me put the dgControl of me into theGrid put the dgIndex of me into tIndex -- get the index of the current grid item put the dgIndexes of me into tList -- get list of grid indexes in display order put itemoffset(tIndex,tList) into toff --find the current index in the ordered list put item (toff -1) of tList into tpreIndex -- get the index of the previous grid item if tpreIndex = 0 then set the visiable of group "spacer" of me to true -- we are the first grid item, so show the spacer else put the dgDataOfIndex[tpreIndex] of me into preData -- get the data for the previous grid item if char 1 of preData["LastName"] = field "spacerLable" of me then set the visiable of group "spacer" of me to false -- no difference yet else set the visiable of group "spacer" of me to true -- we found a difference end if end if end FillInData -----Original Message----- From: use-livecode-boun...@lists.runrev.com [mailto:use-livecode-boun...@lists.runrev.com] On Behalf Of Pete Sent: Tuesday, October 18, 2011 3:29 PM To: How to use LiveCode Subject: Re: Resizable DataGrid Question The selectionchanged message sent to the datagrid includes the index of the current and previous selected datagrid rows as parameters. I'm not sure if that will help though, since this happens outside of the custom behavior where the LayoutControl handler sits. Another way might be to store the index/line number of the row in a custom property of the datagrid and get it back when you need it (and before overwriting it with the current index/line of course!) Have you considered doing this in the source data by inserting an extra row with some sort of indication that it represents a sort break?
