Bug report

When tasks on the same level are dragged and dropped in order to change their relationship as parent - child, the entire Gantt collapses

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@NeliK/EZOXuguC
2. Expand 'Task 1'
3. Drag Task 4 over Task 5 and drop it so it could become its child

Current behavior

The entire Gantt is collapsed.

Expected/desired behavior

The current expanded/collapsed state should not be changed.

The issue is a regression starting with version 2020.3.1021

Bug report

When the culture is changed the NumericTextBox with decimals does not accept valid values when it is rendered inside an editable popup. The issue can be observed when the NumericTextBox is rendered for editing in other components such as Gantt and Grid.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@gdenchev/UKAVAnaZ
2. Try to edit a cell and decrease the number either by entering digits or by using the arrows.

Current behavior

A validation error that the value is not valid appears.
The same behavior occurs in the Gantt component if you try to edit a task, then select Resources and try to edit the Units value - https://dojo.telerik.com/@NeliK/uZepIbId

Expected/desired behavior

The value of the NumericTextBox should accept changes when the culture is set.

When there is a selected item and filtering is performed in the Gantt, sometimes a task in the new filter result is displayed as selected.

Reproduction of the problem

2. Filter the tasks by ID 18
3. Select the task with ID = 18
4. Filter the tasks that have ID equal to 11

Current behavior

Sometimes the task with ID 11 is marked as selected. The issue does not appear consistently, so you may need to perform the test multiple times.

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.

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!

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

With e.preventDefault in the save event of the Gantt, the TreeList becomes unresponsive when blurring a task field.

Reproduction of the problem

1. Open this example - https://dojo.telerik.com/aWaHadaL/17
2. Add a child task under Task 1.
3. Double click on a field of the Child task in the TreeList.
4. Blur the element.

Current behavior

The parent task collapses and becomes unresponsive

Expected/desired behavior

The parent task should not collapse and become unresponsive

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.

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.
