How to drag-reorder rows in a Data Grid?

[smartvn2020]

How do I drag-reorder rows in a Data Grid? I have to ask because, of course, it's not documented. I Googled and found some 10-year old threads but the code there didn't work for me.

Trevor may chime in here, but I believe you have to kludge this. Something like (super-pseudo)"

Code: Select all

on mouseDown put the value of the  "mouseLine" into startLine
create a phantom field containing startLine
on mouseMove set the y value of the phantom to the mouseV
on mouseUp put the value of the mouseLine into endLine
get the dgText of the DG
switch the contents of the two lines
set the dgText to the new configuration

Seems easy...

Hi

Data grid forms now have a dgEditMode property. When in edit mode, the data grid displays an action control of the left hand side of each row and a reorder control on the right that allows you to drag-reorder rows.

We have a lesson on this here

https://lessons.livecode.com/m/datagrid ... -data-grid

If you just want the re-order control and not the action control you can do

Code: Select all

set the dgProps["edit mode action select control"] of group "Data Grid Form" to empty

I hope that helps.
