Hi,

Want the ability to filter on the resource column.

Dojo example.
https://dojo.telerik.com/iZixAfiV

Would like to show column grouping for a few columns in the RaddGantt.

e.g.

• Planned Start and Planned End to be grouped under Planned
• Actual Start and Actual End to be grouped under Actual
• Financial Detail columns to be grouped under Task Financials

Also, would like to add to the query, how can I have the Gantt chart with the dates shown vertically as in the image attached. I don't want the Week or Month name coming in the grouping. Just dates in the timeline view.

Reference - Feature request submitted for RadGantt for ASP.NET AJAX

Implement support for external editor in the Gantt. Instead of using an editor template or calling the editTask method, make possible Gantt tasks to be updated without opening the default editor.

A modification in a child task, e.g. changing its start date, should also update the summary task.

Bug report

Reproduction of the problem

Reproducible in the Columns demo: https://demos.telerik.com/kendo-ui/gantt/columns

1. Filter by "Title" -> contains "Market". Only the child "Market" will be visible in the parent "Research" task.
2. Edit "Market" and set it percentComplete to 100%.

Current behavior

The parent's percent complete is also set to 100%. This is incorrect, since the other children of parent are not removed from the dataSource, they are just visually filtered. The problem becomes more evident, if the filter is cleared. Then the parent keeps its 100% value, even though it contains child tasks with percentComplete less than 100%.

Expected/desired behavior

The parent task percent complete should be consistent to the behavior without filtering applied. Using the same example, this means: on updating "Market" to 100%, Research should change its percentComplete to 49%, taking into account all of its children percentComplete values.

Hi Team,

I would like to request a way to export a larger amount of records fast and easily with the Kendo UI Gantt.  I have tried with over 800, but it runs sluggish.  I am aware of the limitations, but would like to request a faster way to export to PDF.

Thank you!

Bug report

The change event incorrectly triggers at initialization of the Gantt - Regression with 2022.1.301
Also, the event does not trigger when selecting a task from the timeline - Regression with 2022.3.913

Reproduction of the problem

1. Open this example - https://dojo.telerik.com/@martin.tabakov@progress.com/OVigiKEX/3
2. Check the Kendo Console - the change event triggers right after initialization
3. Select a task from the Gantt timeline - the change event doesn't trigger

Current behavior

Change event triggers after initialization and does not trigger after selection in timeline

Expected/desired behavior

Change event shouldn't trigger after initialization and should after selection in timeline

Hi Team,

I would like to request the functionality to easily persist the state of the Kendo UI Gantt like in this Kendo UI Grid example.  Maybe include getOptions/setOptions methods for the component. 

Thank you!

Bug report

When there are tasks with duration only in non-working days and showWorkDays is enabled Gantt displays unnecessary arrows for those tasks.
A similar issue appears also in case there are tasks with resources. In case the task's duration is only on non-working days the text of the resource still appears although showWorkDays is enabled.

Reproduction of the problem

1. Open Dojo and the Dojo with resources - https://dojo.telerik.com/@NeliKondova/IKUnuRec

Current behavior

When showWorkDays is enabled, the tasks with duration only in non-working days are not visible. However, unnecessary arrows for dependency tasks and text of the resources are displayed.

Expected/desired behavior

When showing only working days is enabled there should be no arrows for the tasks with dependencies and no resources text on non-working days

Hi,

Currently, you can change start OR end for the package without problems, and therefore you can change the duration this way, but for the project or phase, it is not possible.

Since these dates are changeable one by one manually through the table on the left or popup form, there is no logical reason why they can't be changed in the timeline as well.

Please could you consider adding this to the gantt widget.

Thank you very much.

Bug report

When the duration of a task is edited in the Task Duration column in Gantt in the save event handler e.task.taskDuration returns the new duration value. With versions, before 2020 R3, the old task duration value has been returned.

Reproduction of the problem

1. Open the Dojo
2. Edit the value in the 'Task Duration' column and observe the result in the browser`s console.

Current behavior

With the current version, the new task duration is returned.

Expected/desired behavior

The returned e.task.taskDuration should return the previous task duration in order to be consistent with the behavior before 2020 R3

Regression since 2020.3.915

Hi Team,

I would like to request an easy, built-in way to format the dateTimePickers with the popup editor for the Kendo UI Gantt.  Currently, the validation will not allow for the editor to be set to a specific format without creating a dedicated editable.template.

Thank you!

Bug report

When a value in the TreeList nested in the Gantt is edited and is initially selected using the mouse, the save event is fired, but the e.values is undefined. Also, the value is changed back to the initial one.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@NeliKondova/arUgAguv
2. Click in the 'Task1' cell to edit and mark the entire text using the mouse
3. Type some text and press 'Enter' - The issue will not be replicated in case the edited mode is exited through clicking in another cell, but only by pressing Enter.
   screencast

Current behavior

The Edit and Save events are fired. The value of the e.values in the save events is undefined. The value of the cell is changed back to the initial one.

When the value of the cell is not marked initially with the mouse, but the user starts typing immediately after clicking in the cell the issue is not replicated. Also, only the Save event is fired and the new value is present in e.values

Note: The issue might be related to the following behavior in the TreeList: When the steps described above are followed in the TreeList - the save event is fired, but actually the edited mode is not exited - Dojo

Expected/desired behavior

The behavior should be consistent. The same events should be fired in case the edited mode is exited by pressing 'Enter' and by clicking in another cell and e.values should contain the updated value.

Hi folks,

I am using the Gantt control and somtimes, I correctly do not have any data to show in it.

In this case, in the left-side of the Gantt (which is technically a Grid), the message "No records to display" is shown.

Since I am using Kendo with kendo.culture('de-CH') (Swiss German) and also the Swiss German messages, I would expect the message to be translated there as well.

Especially, when I am looking into the messages-file (https://kendo.cdn.telerik.com/2021.1.330/js/messages/kendo.messages.de-CH.min.js) and it does in fact contain the translation for the Grid's noRecords. And it's also there in the JavaScript code when having the Swiss German culture loaded:

console.log(kendo.ui.Grid.prototype.options.messages.noRecords);

Could you please have a look at this and make the Gantt component respect the translations?

For better illustration, I have prepared the following Dojo, that uses Swiss German culture and displays an empty Gantt chart: https://dojo.telerik.com/iXuKeYaZ

As I ran into this problem while using Telerik for ASP.NET Core, I am looking forward to a solution that that works there too.

Thanks in advance!

Kind regards,

Janick
