Bug report

The dependencies in the Gantt can not be removed.

Reproduction of the problem

1. Open the demos - https://demos.telerik.com/kendo-ui/gantt/index
2. Select a dependency line and press the 'Delete' key.

Current behavior

Nothing happens, there is no confirmation popup, and the dependency is not removed.

Expected/desired behavior

A confirmation dialog for confirming the deletion appears and the dependency should be removed.

The issue is a regression starting with the 2023 R2 SP1 ( 2023.2.718) version

Environment

• Kendo UI version: 2023.2.718
• Browser: [all ]

That is for scenarios when the start of one task is dependent on the end of another task. In such a case, if the end of the initial task changes, the start of the dependent task should also change automatically.

Bug report

When the autoSync option of the GanttDependencyDataSource is set to true, two identical requests are sent to the server when creating a new dependency.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/AGOJUyAp
2. Open the Network Tab
3. Create a new task dependency

Current behavior

Two identical Create requests are sent to the server

Expected/desired behavior

Only one request should be sent to the server

Bug report

If you expand/collapse the top parent node, it is marked as dirty.

2. Collapse the top node

Current behavior

The top node is marked as dirty when collapsed

Expected/desired behavior

The top note shouldn't be marked as dirty upon collapsing

It would be nice if tasks could be added to gantt that are missing a start date, end date or both dates.

For our use case this feature is not only useful, but mandatory. We are visualising a project workflow that goes through several phases and steps. Within our application, the client fills in the dates for these tasks and milestones as the project progresses. Not all dates are filled-in at all times, however when a project manager creates a gantt chart, he wants to see all the tasks. A task without a date is an information in itself. 

Currently we have to create a fake date entry for tasks without dates.

As all grids, the kendo Gantt chart's rows change their color when hovering. However, the background overlaps the border between columns and makes them disappear for the hovered row.

You can reproduce the described behavior by hovering one of the rows in this DOJO.

Bug report

When there are Grid and Gantt on the same page and a column in the Gantt has reordered an error in the console is thrown:
kendo.all.js:133531 Uncaught TypeError: Cannot read properties of undefined (reading 'lockable')

Reproduction of the problem

1. Open the Dojo. There is no relation in the configuration between the Grid and the Gantt widgets.
2. Reorder the columns in Gantt

Current behavior

The following error is thrown:
kendo.all.js:133531 Uncaught TypeError: Cannot read properties of undefined (reading 'lockable')

Expected/desired behavior

There should be no error in the console when reordering columns in Gantt, even if there is a Grid on the page.

The issue is a regression starting with: 2021.3.1207

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!

Add a way to highlight the critical path in the Gantt Chart. This is a basic feature in project management and would be really great if you can implement,.

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

Bug report

When you collapse a selected task in the Gantt, the selection is lost

Reproduction of the problem

1. Open the Gantt Overview demo - https://demos.telerik.com/kendo-ui/gantt/index
2. Select the Software validation task
3. Collapse the selected task

Current behavior

The selection is lost

Expected/desired behavior

The selection should be preserved

Incorporate page breaks into the Gantt PDF Export and include option to repeat column headers on each page.

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!

Problem: We really want to fit Gantt's on particular paper sizes (def. landscape A3); however, using the paperSize option doesn't really work as the output (font size, row heights, etc.) end up being too big and not suitable.

And for the majority of the time, paperSize set to auto creates an output (font size mostly) too small.

Rock and a hard place... 

Solution 1: When pdf.paperSize is not set to auto i.e. A3, A4, etc. Allow a percentage scaling to be set, ideally individually, on X and Y.

Solution 2: Scale fonts and scale timeline on X axis maintaining taskList width.

Ultimately, get a large plan to fit on landscape A3.

Bug report

In a Gantt that has a DropDownList as editor in the TreeList, if you click on the DropDownList's wrapper to open the widget, it will close the cell instead.

Regression introduced with 2022 R1

Reproduction of the problem

1. Open this example - https://dojo.telerik.com/OlOCIkOZ/3
2. Double click to edit the Status field
3. Click on the DropDownList wrapper.

Current behavior

The cell closes.

Expected/desired behavior

The cell should remain open and the DropDownList should open

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.

Currently, when a child task in the Gantt is edited the start/end time of the parent task will be updated accordingly. I would like to have the possibility to disable this behavior and have the possibility to edit the child's tasks' start and end times without updating the start and end times of the parent task.

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

Bug report

When the end date of a task is edited in the End Time column in Gantt in the save event handler e.task.end returns the new end date value. With versions, before 2020 R3, the old end task value has been returned.
The behavior is inconsistent with editing a task through dragging or by double-clicking on a task as in such case the previous value of the end task will be returned

Reproduction of the problem

1. Open the Dojo
2. Edit the date in the 'End Time' column and observe the result in the browser`s console.

Current behavior

With the current version, the new end date is returned.

Expected/desired behavior

The returned e.task.end should be consistent with the other ways of changing the date e.g. dragging or double-clicking on the task.
