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.
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
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,
I use a Gantt chart like this one.
<script>
$("#gantt").kendoGantt({
dataSource: [{
id: 1,
orderId: 0,
parentId: null,
title: "Task1",
start: new Date("2021/6/1"),
end: new Date("2021/6/3")
}],
range: {
start: new Date("2021/05/31"),
end: new Date("2021/12/01")
},
views: ["month"]
});In the example, the Gantt chart starts on May 31, 2021.
In the first header line we see the month of May, followed by July. There is no month of June.
https://dojo.telerik.com/@lydbell/ULAPUdOV
This only happens when the last day of the month is Monday .
If a date is configured in Gantt by using the date method or views.date configuration and then a task is edited, the Gantt displays the initial date after editing a task.
After the task is edited the horizontal scroll position is set to its initial position, not to a position according to the edited task. Thus, the user needs to scroll again in order to find the edited task.
The behavior is not the same when the date method/configuration is not used. Also, the behavior is not the same if we first switch between the 'Day', 'Week', 'Month' views before editing a task.
Even if the initial date of the Gantt is configured, when the user edits a task, the date should not be persisted. The horizontal scroll should be in the same position as before editing a task.
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
Bug report
Error is thrown in the console when an event is dragged.
Reproduction of the problem
Dojo: https://dojo.telerik.com/ORuSEYoW
Expected/desired behavior
Error shall not appear
Environment
Kendo UI version: [all]
jQuery version: [all]
Browser: all
The dependencies in the Gantt can not be removed.
Nothing happens, there is no confirmation popup, and the dependency is not removed.
A confirmation dialog for confirming the deletion appears and the dependency should be removed.
When selecting the Month View of the Gantt, unexpected blank space appears and the cell headers are not properly aligned.
To reproduce the problem, open this demo:
https://demos.telerik.com/kendo-ui/gantt/basic-usage
And Click Edit in Kendo UI Dojo:
https://dojo.telerik.com/OparoYUJ
Zoom out the browser so the Gantt has some larger Width and you will notice the blank space + misaligned headers:
The same issue can be observed in the Getting article: https://docs.telerik.com/kendo-ui/controls/gantt/get-started
When tasks on the same level are dragged and dropped in order to change their relationship as parent - child, the entire Gantt collapses
The entire Gantt is collapsed.
The current expanded/collapsed state should not be changed.
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.
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
The value of the NumericTextBox should accept changes when the culture is set.
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.
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.
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
The tasks that have not been selected, should not be displayed as selected after filtering.
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.
The draggable item is initialized with a negative "left" CSS style. The task name is partially visible or not visible at all.

The draggable item should be visible. The task name should be visible.
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
If you expand/collapse the top parent node, it is marked as dirty.
Regression introduced with R1 2023
The top node is marked as dirty when collapsed
The top note shouldn't be marked as dirty upon collapsing
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')
The following error is thrown:
kendo.all.js:133531 Uncaught TypeError: Cannot read properties of undefined (reading 'lockable')
There should be no error in the console when reordering columns in Gantt, even if there is a Grid on the page.
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
Change event triggers after initialization and does not trigger after selection in timeline
Change event shouldn't trigger after initialization and should after selection in timeline
When you collapse a selected task in the Gantt, the selection is lost
The selection is lost
The selection should be preserved
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
The cell closes.
The cell should remain open and the DropDownList should open
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.
With the current version, the new task duration is returned.
The returned e.task.taskDuration should return the previous task duration in order to be consistent with the behavior before 2020 R3
