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 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 ]

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 ]

When rendering this minimal DOJO containing a Kendo-UI Gantt chart in Chrome, space in the grid header is reserved for the vertical scrollbar on the right hand side:

When using Firefox, space is still reserved, although scrollbars collapse by default and therefore do not need any space:

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.

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. 

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]

The Gantt desperately needs a way to position the title somewhere other than inside bar. Other Gantt charts I have used will allow you to place the title to the right of the bar so the title is still displayed in its entirety regardless of the pixel size of the rendered task bar.

Other kendo charts already allow similar configuration options. I have tried using the taskTemplate and css which I can get to show on the screen just below the bar however the title is then not visible in the pdf view.

, taskTemplate: function (task) {
    // move label just below and to the far right of the task bar
    return '<span class="task-label" style="position:absolute; right:0; color:#000;">' + task.title + '</span>';
}

Please advise.
