Video: Part 4 – Implementing Drag & Drop functionality

Video: Part 4 – Implementing Drag & Drop functionality

Do you want to add Drag & Drop functionality to your APEX applications?
That’s what this video is all about.

You’ll see me working on the list created in the previous episodes (Part 1, Part 2 and Part 3) and add the necessary JS to implement.

During the video, I follow this companion blog post (rimblas.com/blog/2016/08/implementing-drag-drop-in-your-apex-applications). Bookmark it and use it as a reference in the future.

In this 41 minute video you’ll find:

  • 02:08 to 03:22 — Add the jQuery UI library to the page.
  • 03:23 to 04:40 — Explaining how elements get re-arranged.
  • 04:40 to 08:02 — Make region/report sortable.
  • 08:02 to 16:04 — Identify the elements to sort and explaining how we actually capture the new order.
  • 16:05 to 24:17 — The AJAX call to save changes (plus some debugging), wrapping up.
  • 24:18 to 42:25 — Implementing the same thing on a regular Classic Report.

  1. Thanks for new great presentation. But “it’s easier than you think” — I think unfortunately no, not easier :) I’m sure most of apex developers couldn’t immediately reproduce this solution correctly without copy/pasting your code.

  2. I removed the call to the updateDisplaySeq function and also removed the ORDER BY clause from the SELECT statement and it also worked.

    function makeSortable(pRegionID) {
    $r = $("#report_" + pRegionID);
    $r.find("[headers='ID'] a").each(function(){
    $(this).parent().parent().attr('data-id',$(this).data("id"));
    });

    $r.find("table.t-Report-report").sortable({
    items: 'tr'
    // , update: function(event,ui) { updateDisplaySeq(); }
    , update: function(event,ui) {}
    });
    }

  3. Wow !! Just watched your video, and it is excellent !! You go into details where the devil is and that is unique…

    • I am new at Oracle Apex and I was searching for tutorials as u described with details.
      Thanks a lot.

  4. Your videos are so very helpful. Thank you so much. I expected the display seq numbers in the classic report to change after refresh but they did not seem to. Did I miss something?

  5. Hello jorge,

    I use Oracle APEX 19.1.0.00.15, I add the library #IMAGE_PREFIX#libraries/jquery-ui/1.10.4/ui/minified/jquery.ui but I had this error:
    GEThttps://lc000020.info.ratp:8443/i/libraries/jquery-ui/1.10.4/ui/minified/jquery.ui?v=19.1.0.00.15
    [HTTP/1.1 404 Not Found 18ms]

    I remove this URL to skip this error but I had a json parsing error when I drag the element list (I use the javascript function of update with the f01 and without to_string), this is the error of Json parsing:
    Error: SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

    I don’t know if this error have a relation with the library not found in apex 19 server.

    Can you help me please, I need this drag and drop a lot and thanks.

    Regards,
    Rached
