They are not currently documented though. The following code will create a drag image from one of the rows and turn on tracking so that a horizontal bar appears within the DataView where the drop will occur. ``` on dragStart set the dvDragImageRow of me to item 1 of the dvHilitedRows of me set the dvTrackDragReorder[the dvHilitedRows of me] of me to true set the dragData["private"] to the dvHilitedRows of me # dragdata has to be set to something. end dragStart ``` The DataView will then send a `DragReorderRows` message when the drop occurs. Since the DataView doesn't know anything about your data source it is up to the developer to update the data source and refresh the view. The `DragReorderRows` handler looks like this: ``` command DragReorderRows pRowsBeingDragged, pMoveToRow, pDroppedAfterRow put "pRowsBeingDragged:" && pRowsBeingDragged & cr & \ "pMoveToRow:" && pMoveToRow & cr & \ "pDroppedAfterRow:" && pDroppedAfterRow end DragReorderRows ``` -- Trevor DeVore ScreenSteps www.screensteps.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

Re: Levure Dataview Question
Yes would be good to know. I've seen demos of drag- reordering, and scripted a few experiments - but seeing that work on mobile for something as visually complex as a data grid (or Levure dataview) I've no seen. My suspicion is that that sort of visual drag drop animated feedback is best done in HTML. But with the steady progress in accelerated rendering and widgets perhaps it is possible to acheive the same level of quality using native Livecode.

Re: Levure Dataview Question
If there is I'd like to know. I created a couple arrows that sit to the left of the datagrid. Any time you select a row, the grid sends a message to the group and moves the arror group adjacent to it. Obviously, clicking up or down relocates that row. You can just see why drag-drop reordering might not be useful. Datagrids have a sort function, so it would have to be that if you drag-reorder something, the sort for that datagrid would have to be turned off. That would mean you would have to keep turning it back on when you repopulated the grid.
