Well, now I understand.

First of all, you will need additional field in the alias used by grid. This could be numeric field that will be used to order rows. Initial value of this field match to the recno() (record number) for each row. Alias should be indexed by that field. The implementation here is very depended on what you use as RecordSource of grid: cursor (result of SQL SELECT), view or table?

Than you can organize drag&drop in grid. This is quite a bit of mess, because you will require to play a lot with grid properties and objects. I recommend you to build it manually handling MouseDown, MOuseMove and MouseUp events.

Once you finished drag&drop part and know exactly which row where should be placed, just change numbers in the sorting field to re-order rows, than grid.refresh to show rows in new order.

>Drag and Drop - where you click on a row (probably on the far left), hold down the mouse, drag the row up two rows, and then drop the row in the new spot.

>>>Client wants to be able to self sort a grid. Currently I present the grid in the order that rows were created. I keep a sequence number on the table that determines my original sort. But now the client wants the ability to change the order of the displayed rows. What are some good obtions for accomplishing this? Can you drag and drop rows in a grid?
