Suggestion: add a link to stringgrid fpdoc documention. It is still minimal, but I have hopes that it will grow this year. Vincent 01:46, 4 Mar 2005 (PST)

- For Sorting. By Sorting I understand that the user can click the column header, and a visual mark (usually an arrow) will show the sorting direction, this can be acomplished right now drawing the mark in the cell title in OnDrawCell event, for the sorting operation, if the user had assigned an event handler for OnCompareCells then doing for example grid.Sort(true, 2) (probably in a handler for OnTitleClick for dbgrid or HeaderClick for other grids) will sort column index 2 by calling OnCompareCells. However for dbgrid probably the underlaying dataset might have a better sorting mechanism and then such must mechanism needs to be called in OnTitleClick. The drawing part could be implemented standard in the grids, having the user to supply a images for three status (arrows), ascending, descending, unsorted, an alignment for the image. Moreover, specific events could be added in the "sorting" mode, a better spec could be described here. --jesusrmx 23:25, 26 Apr 2005 (PDT)
