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.

Regression since 2020.3.915

2. Add a child task under Task 1.
3. Double click on a field of the Child task in the TreeList.

Current behavior

The parent task collapses and becomes unresponsive

Expected/desired behavior

Hi Team,

I would like to request an easy, built-in way to format the dateTimePickers with the popup editor for the Kendo UI Gantt.  Currently, the validation will not allow for the editor to be set to a specific format without creating a dedicated editable.template.

Thank you!

Bug report

The menu that determines where to add new task incorrectly appears after creating a new task and editing an existing one.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/uBAHUgOy
2. Add new task.
3. Randomly edit another task so that no item is selected in the Gantt TreeList.
4. Press the Add Task button again.

Current behavior

The Add Child/Above/Below menu appears unexpectedly.

Expected/desired behavior

The menu should not appear and a new task should be added at the bottom of the list.

When summary/parent tasks in the Gantt are edited in the timeline the duration of the parent task is not always consistent with the net duration of its children.
Please review this Screen capture for the described behavior: https://www.screencast.com/t/la1PzVZaYc


This issue can be avoided, if the duration of the parent tasks can be configured to be fixed. Then the parent task's duration will only be dependant on the duration of its children.

Furthermore the timeframe of the parent task would be editable by changing the starting date.

Currently Task Template and Toolbar Template doesn't integrate with AngularJS. E.g. it is impossible to use {{ $ctrl.mymember }} or <my-angular-component></my-angular-component> for the task template in gantt.

Hi,

Want the ability to filter on the resource column.

Dojo example.
https://dojo.telerik.com/iZixAfiV

 

Currently there is only template for Gantt
I need to be able to control the tooltip behaviour.

showOn:"mouseenter", "click" , "focus"
autoHide: true, false
position: "bottom", "top", "left", "right", "center"

Bug report

When tasks are reordered in Gantt duplicated requests are sent for updating.

Reproduction of the problem

1. Open the Gantt Overview Demo
2. Reorder two tasks and inspect the requests in the Network tab

Current behavior

For example, in case two tasks on the same level are changing their places, four requests are sent, two by two the requests are the same.
In case a task is moved on a different level multiple requests are sent, as all are duplicated.

Expected/desired behavior

There should be no duplicated requests when reordering tasks in Gantt

This is a regression introduced with R3 2020 (2020.3.915)

Bug report

When the validation message appears that the Start Date should be before the End Date, picking a proper End Date does not automatically remove the validation message in the Gantt.

Workaround: call the validate method in the change event of the End DatePicker.
https://dojo.telerik.com/@martin.tabakov@progress.com/IQiRukIN/11

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/@martin.tabakov@progress.com/IQiRukIN/10
2. Edit an existing task or create a new one.
3. In the Start DatePicker, choose a date that is after the EndDate, so that the validation message would appear.
4. Pick an EndDate that is after the StartDate.

Current behavior

The validation message remains and the user must again focus and blur the Start Date picker for the message to disappear.

Expected/desired behavior

The validation should be removed automatically after picking a EndDate that is after the StartDate.

I am working with AngularJs and in the normal Grid its possible to add ng-click Events to Columns with the Attribute Property for the ColumnDefintion, that would be great if this works too for the Gantt Chart. Because I can add a ng-click to Gantt Column and with the event I can get the current row Id and open my own custom Modal to edit the Values.

Add possibility to automatically center the Gantt timeline to a given date onload.

Bug report

When there are tasks with duration only in non-working days and showWorkDays is enabled Gantt displays unnecessary arrows for those tasks.
A similar issue appears also in case there are tasks with resources. In case the task's duration is only on non-working days the text of the resource still appears although showWorkDays is enabled.

Reproduction of the problem

1. Open Dojo and the Dojo with resources - https://dojo.telerik.com/@NeliKondova/IKUnuRec

Current behavior

When showWorkDays is enabled, the tasks with duration only in non-working days are not visible. However, unnecessary arrows for dependency tasks and text of the resources are displayed.

Expected/desired behavior

When showing only working days is enabled there should be no arrows for the tasks with dependencies and no resources text on non-working days

Hi!

For small tasks delete button overlaps a button for creating dependencies. How can we fix this behaviour?

I would like to be able to toggle the planned vs actual view on Gantt outside of the Gantt toolbar. This can be achieved using private methods as in the example below and the Dojo linked here:

```

function changeValue(){
          var gantt = $('#gantt').data('kendoGantt')
          var timeline = gantt.timeline;

          var showPlanned = $('#gantt input.k-gantt-planned-switch').data('kendoSwitch').check()
          $('#gantt input.k-gantt-planned-switch').data('kendoSwitch').check(!showPlanned)

          gantt.wrapper.toggleClass("k-gantt-planned");
          timeline._setPlanned(!timeline.options.showPlannedTasks);
          timeline._render(gantt.dataSource.taskTree());
          timeline._renderDependencies(gantt.dependencies.view());
 }

```

However, having a public method for showing the planned tasks (for example showPlannedTasks(true) ) would be very helpful.

                    

Bug report

If you select a custom view in the Gantt and shrink the window so that a DropDownList would appear, the custom view does not appear as selected in the DropDownList.

Reproduction of the problem

1. Open this example - https://dojo.telerik.com/@martin.tabakov@progress.com/ECOhusOc
2. Shrink the browser until the DropDownList appears on the Gantt toolbar.
3. Select the Quaterly custom view.

Current behavior

Quaterly custom view is not displayed as the selected value of the DropDownList

Expected/desired behavior

Quaterly custom view should be displayed as the selected value of the DropDownList

Environment

• Kendo UI version: 2021.2.511

We have many tasks, and rendering in gantt so slowly. If use Pager with datasource, gantt show items on level 2 and above.
Please, add virtualization + virtual scroll in gantt control

Bug report

When planned tasks are displayed and rowHeight is set to the Gantt, the dependency lines are displayed incorrectly

Reproduction of the problem

1. Open the Dojo

Current behavior

Dependency lines are misplaced

Expected/desired behavior

The dependency lines should be rendered on the correct position

Workaround

Set the padding-top to '.k-task-wrap' elements

Hi Team,

Currently the Actual start and Actual end datetime fields are required fields. This is an error in principle as the Actual start and Actual End cannot be required for the following reasons:

The practical application of using the Gantt for Planned vs Actuals purposes of any kind is that a task is initially planned by setting the Planned Start and Planned End date of the task. A planned task has not necessarily begun, so there is no actual start or end of the task. For this reason, the users cannot yet fill the actual start and actual end. Therefore the Actual Start and Actual End should allow for the fields to be non-required fields.

Thanks!
