Hi...

In the Syncfusion Gantt Control, it's very easy to show/set the task dependencies (see screenshot of task properties bellow).

 

How to do the same in the jQuery Gantt?

Thank you.

Hi,

I am trying to upgrade from R3 2021 to latest version of the library. 

However, I noticed that from version 2022.1.301 - whatever happens on gantt list, change event is triggered, what before wasn't case.

For example, if I select task A, and try to collapse another phase, change is triggered, selection of task A is lost.

Behavior is reproducible in the following Dojo, just change library version to any before 2022.1.301  to see old behavior and to that one or after for a new behavior.

If new behavior is not a bug, please could you advise on how to persist selection of the task on these side actions (collapse phase for example).

If you need any info, I will be happy to help.

Regards,

Vedad

Hi,

I have a question regarding Gantt chart performance, when having large amount of data. I expect that my Gantt chart will have ~10.000 rows minimum, but I am starting to face some performance issues  with this amount of data.  The widget becomes laggy and responses to user actions with a delay.

So my question is what is the maximum row count that Gantt supports?  Maybe I've reached it? 

Thank you)

Hi,

I had to add the grid to part of my gantt page in the app and as soon as I added the grid, gantt drag and drop of columns started to fail.

On column drop lib fails with the following error:

Uncaught TypeError: Cannot read properties of undefined (reading 'lockable')
    at init._allowDragOverContainers (kendo.all.js:311085:87)
    at init._dropTargetAllowed (kendo.all.js:311085:87)
    at init.drop (kendo.all.js:311085:87)
    at init.trigger (kendo.all.js:311085:87)
    at init._trigger (kendo.all.js:311085:87)
    at init._drop (kendo.all.js:311085:87)
    at kendo.all.js:311085:87
    at init._withDropTarget (kendo.all.js:311085:87)
    at init._end (kendo.all.js:311085:87)
    at init.trigger (kendo.all.js:311085:87)

Problem is reproducible in the following Dojo

To reproduce issue, just try to change the order of the columns in the gantt widget.

Result: Widget breaks on drop and any drag or drop is not possible. Browser console shows error described above.

Expected result: Columns reordered

Tested with Chrome and Firefox.

If there is anything else I can do to help, please let me know.

Hi,

is there any way to enable resizing duration (start or end) of the parent/container element in gantt, via drag on the timeline (like it is possible for tasks)?

For example I want to be able to change start or end of "Software validation, research and implementation" from standard demo.

I couldn't find any setting that allows this, so is it possible and what would be proper approach?

Thank you very much.

Regards

Hi,

I am not sure if this is a bug or expected behavior, but I observed that when I create element in Gantt widget using pushUpdate, gantt timeline "jumps" to some position. For me locally it jumps to today, on example dojo (attached below) it jumps to other position.

I did some debugging locally and as I could see this line in code triggers this focus:

            pushUpdate: function (items) {
                if (!isArray(items)) {
                    items = [items];
                }
                var pushed = [];
                for (var idx = 0; idx < items.length; idx++) {
                    var item = items[idx];
                    var model = this._createNewModel(item);
                    var target = this.get(model.id);
                    if (target) {
                        pushed.push(target);
                        target.accept(item);
                        target.trigger(CHANGE); //FOR ME HERE IT FOCUSES
                        this._updatePristineForModel(target, item);
                    } else {
                        this.pushCreate(item);
                    }
                }
                if (pushed.length) {
                    this.trigger('push', {
                        type: 'update',
                        items: pushed
                    });
                }
            },

Behavior can be observed on this dojo, with the following steps:
 - run dojo

- position gantt timeline somewhere in the future (i tried several dates)

- click 'add item' button to add EXAMPLE element via pushUpdate

Result: Gantt "jumps" the timeline (at least for me) to 05.07. - 06.07.

 

Thank you and regards

Hi,

I am trying to use Gantt widget with Drawer located at the right side. 

For some reason, when I position drawer to the right, even with mini mode it is always outside of the screen (horizontal scroll appears) - if i expand drawer, it basically expands it to the right, and remains outside screen, horizontal scroll just expands area.

When drawer is positioned on the left it works normally (pushes gantt for width of drawer).

Behavior can be observed in following Dojo:

https://dojo.telerik.com/EdIQaXeY

Thank you very much

Regards

Can you make Gantt chart dependency read-only (editable = false) but keep the tasks editable
