With this customization it will be possible to use checkboxes or combo boxes and normalize the selection of data. Actually is possible to use only text and date columns.
Most of the time project managers would like to compare planned start & end dates vs actual start and end dates in gantt view. This feature is not supported by current Gantt chart. What I'm envisioning is something similar to the implementation of Gantt chart by Fusion Charts. (http://www.fusioncharts.com/charts/gantt-charts/). Displaying delays in actual task compared to plan would be an an added advantage. This feature may be implemented using a task template, but it's nice to have feature in the control.
In the Gantt table we would like to configure columns: - width - order - locked column - hide/unhide (columnMenu) Same as done in TreeList in Q1 2015
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.
Bug report
The dependencies in the Gantt can not be removed.
Reproduction of the problem
- Open the demos - https://demos.telerik.com/kendo-ui/gantt/index
- 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 ]
Add possibility to automatically center the Gantt timeline to a given date onload.
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
- Open the Dojo
- 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.
Regression since 2020.3.915
Environment
- Kendo UI version: 2022.1.412

Reproduction of the problem
- Open this example - https://dojo.telerik.com/@martin.tabakov@progress.com/OVigiKEX/3
- Check the Kendo Console - the change event triggers right after initialization
- 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 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
- Open the Dojo
- 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
With e.preventDefault in the save event of the Gantt, the TreeList becomes unresponsive when blurring a task field.
Reproduction of the problem
- Open this example - https://dojo.telerik.com/aWaHadaL/17
- Add a child task under Task 1.
- Double click on a field of the Child task in the TreeList.
- Blur the element.
Current behavior
The parent task collapses and becomes unresponsive
Expected/desired behavior
The parent task should not collapse and become unresponsive
Environment
- Kendo UI version: 2022.1.412
- Browser: [all]
Bug report
Reproduction of the problem
Reproducible in the Columns demo: https://demos.telerik.com/kendo-ui/gantt/columns
- Filter by "Title" -> contains "Market". Only the child "Market" will be visible in the parent "Research" task.
- Edit "Market" and set it percentComplete to 100%.
Current behavior
The parent's percent complete is also set to 100%. This is incorrect, since the other children of parent are not removed from the dataSource, they are just visually filtered. The problem becomes more evident, if the filter is cleared. Then the parent keeps its 100% value, even though it contains child tasks with percentComplete less than 100%.
Expected/desired behavior
The parent task percent complete should be consistent to the behavior without filtering applied. Using the same example, this means: on updating "Market" to 100%, Research should change its percentComplete to 49%, taking into account all of its children percentComplete values.
Environment
- Kendo UI version: 2020.3.1021
- jQuery version: x.y
- Browser: [all]
Reproduction:
- Open https://demos.telerik.com/kendo-ui/gantt/pdf-export
- Click "Export to PDF" and open file
- Actual result: there's a lot of blank space on the right
- Expected result: the margin should correspond to the pdf.margin.right option
A working example of the bug is at https://dojo.telerik.com/EPuqExOg with a simple workaround until the bug is fixed. Currently, the percentage textbox doesn't work when in the German language. The date textboxes localize ok.
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
- Open the Dojo - https://dojo.telerik.com/@NeliK/EZOXuguC
- Expand 'Task 1'
- 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 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
- Open the demo - https://demos.telerik.com/kendo-ui/gantt/columns
- Filter the tasks by ID 18
- Select the task with ID = 18
- 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.

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
- Open this Dojo
- Move the Splitter in the Gantt component to the left, in a way at least half of the initially visible TreeView is hidden.
- 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.
