Gantt completely broken

Dear Support,


I have been implementing a customised Gantt control for a couple of months, and I am facing the following issues.


I try to break down the issue list per version:


23.2.7 and lower -> seems incompatible with the current logic (Gantt events missing etc..)

24.1.41 -> unnoted, probably same as above

24.1.43 -> unnoted, probably same as above

24.1.44 -> unnoted, probably same as above

24.1.45 -> Timeline / Taskbar issue

24.1.46 -> Update Dialog - Dependency tab crash

24.1.47 -> Update Dialog - Dependency tab crash

24.2.3 -> Timeline / Taskbar issue, Drag & Drop stopped working


I am going to focus on the latest version - 24.2.3


1, Row Drag and Drop

I use the Gantt RowDropped event to maintain manually the OrderNo property.

It was working well before, but not anymore, it looks like the event is prevented.


2, Timeline / Taskbar editing


The used GridEditSettings are:

                                <GanttEditSettings AllowAdding="true" AllowDeleting="true"

                                                   AllowEditing="true" AllowTaskbarEditing="true"

                                                   AllowSchedulingOnDrag="true"

                                                   ShowDeleteConfirmDialog="true"

                                                   Mode="SfGanttEditMode.Dialog"/>


In the previous versions, it was partially working. The OnActionComplete event is triggered, and I can save the changes on the data level, although the UI is not refreshed. It's true both 'sliding' the item on the timeline, changing the Start or the End date of the task, or creating a relation between tasks (drawing the lines). I had to refresh the page to see the changes.

However, it is working well in Dialog Edit mode.


3, Timeline in general

It doesn't refresh at all. Even after Zooming in or out and so on. It looks like the taskbar is frozen and doesn't adjust to the new timeline settings.


I attached a short video to demonstrate the issues below.


Please let me know if you can identify any of these problems.

I can't send the whole source code since it's part of a larger business application.

If it's required please contact me privately.


Regards,

Istvan
