Bug report

Long Gantt event is not visible since 2022.1.119

Reproduction of the problem

1. Open the Gantt Demo in Firefox.
2. Switch the view to Month.
3. Pick an event row in the chart (e.g. 'Market Research'), and set the End date to 2024-12-31.
4. The event is no longer visible in the right-hand-side of the gantt.

Expected/desired behavior

Gantt event shall be visible

Environment
Kendo UI version: 2022.1.119 or newer
Browser: [all]

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 ]

When the RowHeight of the Gantt is enabled and the planned tasks are shown, the height of the row in the timeline is miscalculated and that creates displacement. 

• https://dojo.telerik.com/EgiGiXUF/5 

Additionally, the task dots used for the dependencies are misplaced in the same scenario as demonstrated in the dojo above. 

When a user switches from navigating by mouse to navigating by keyboard, the focused element in the overview grid is not synchronized. Please follow the instructions below to reproduce the issue using this DOJO:

• click e.g. on the first cell in the "id" column
• using your arrow keys, move the keyboard focus to the last cell of the "id" column
• click the checkbox in the first row (keyboard focus is now lost)
• press the enter key (keyboard focus reappears in the last cell of the "id" column)

Wouldn't a user expect the cell he/she just clicked to be focused? The keyboard focus should be updated even when navigating by mouse.

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

Environment

• Kendo UI version: 2024.2.514
• Browser: [all ]

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.

Environment

• Kendo UI version: 2024.1.319
• jQuery version: x.y
• Browser: [all ]

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 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

1. Open the demo - https://demos.telerik.com/kendo-ui/gantt/columns
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.
screencast - https://somup.com/c0XZ6DgaRA

Expected/desired behavior

The tasks that have not been selected, should not be displayed as selected after filtering.

The issue is a regression starting with the 2022 R1 release

Environment

• Kendo UI version: 2023.3.1114
• Browser: [all]

Bug report

When the tasks in the Gantt's TreeList are moved/dragged an item appears over them. When the visible size of the TreeList is small, dragging tasks inside it results in unavailability to understand which task is currently being dragged because the draggable item is partially hidden.

Reproduction of the problem

1. Open this Dojo
2. Move the Splitter in the Gantt component to the left, in a way at least half of the initially visible TreeView is hidden.
3. Select Task 2 and drag it.

Current behavior

The draggable item is initialized with a negative "left" CSS style. The task name is partially visible or not visible at all.

Expected/desired behavior

The draggable item should be visible. The task name should be visible.

Environment

• Kendo UI version: 2020.1.406
• jQuery version: x.y

Hi,

In Dojo chose Kendo UI 2020 R1 SP2 library and created a Gantt chart with two summaries and a task. Each summary has a child task.

Set rowHeight to 40px.

Expand Summary1. Summary2 changed position and moved to the top of the row.

Collapse Summary1. Summary2 still at the top of the row.

Also, tried with other libraries, the result is the same.

Noticed that if rowHeight is not set, summary doesn't change its position.

Example here: https://dojo.telerik.com/IriJegeX

Please find the screenshot attached.

Team,

Dojo ref : https://dojo.telerik.com/@Aswathi/uXoJoSUq 

When I edit the calendar value and click on any other row/cell it doesn't get saved. If I click outside it gets saved. I see it's due the property 

.

If we set it  editable:true , it's breaking the reorder functionality.

Is there a way to fix this ?

Appreciate your support.

Regards,

Sujith

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

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
