I have a gantt chart with tasks, resources, and assignments. I want to enforce a many-to-one relationship between tasks and resources, that is, I want to be able to assign a single resource to any number of tasks, but each task can only have 1 resource at a time. A (conceptually) simple sample implementation would be to change the checkboxes to a radiobutton in the 'assign' dialog window, from the 'edit' dialog.

I understand there is currently no way to enforce this type of relationship or the restrict the user from selecting more than 1 assignment in the assignment dialog window, so I am requesting a way to do either (or both) of these things. I would imagine a setting in the gantt or taskDataSource for enforcing the relationship, or a setting in the assignment field for switching the dialog box to radio button like behaviour.

Would like to show column grouping for a few columns in the RaddGantt.

e.g.

• Planned Start and Planned End to be grouped under Planned
• Actual Start and Actual End to be grouped under Actual
• Financial Detail columns to be grouped under Task Financials

Also, would like to add to the query, how can I have the Gantt chart with the dates shown vertically as in the image attached. I don't want the Week or Month name coming in the grouping. Just dates in the timeline view.

Hi,

Want the ability to filter on the resource column.

Dojo example.

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

We have been looking into the possiblity of using Telerik Test Studio; however, the Gantt Chart control from Kendo is a key part of our application, and having a Translator to help with validating the control contents would be really helpful.

The Gantt widget has support for parent-child relationship, but the hierarchy only works, if the title property of a gantt task is used in column definitions. So if you have for example only an ID column in your column definition, you can not expand/shrink hierarchy.

Suggested improvement: make this option configurable via the columns declaration by adding "expandable: true/false" or make the hierarchy appear in the first column if the title property is not in the columns declaration.

You can have thousands of lines (rows) of project data....you can't load the entire plan and scroll through it

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.

I am Working With Gantt in AngularJs, but I dont found way to make the Critical Path And Baseline in Gantt. 

is this possible?

https://dojo.telerik.com/UtUtiQER

Reproduction:

1. Open https://demos.telerik.com/kendo-ui/gantt/pdf-export
2. Click "Export to PDF" and open file
3. Actual result: there's a lot of blank space on the right
4. Expected result: the margin should correspond to the pdf.margin.right option
   

It would be great if text within the Treelist section of the Gantt chart would wrap.

Configuring the rowHeight increases the height of the table row, but the long text is still not wrapped. Here is a sample dojo demonstrating the current behavior: https://dojo.telerik.com/EtEViREL

An ideal solution would be something that increases the size of the corresponding timeline row to match the treeview row, and to move down things like dependency arrows so it looks like everything still matched properly.

Bug report

Reproduction of the problem

Reproducible in the Columns demo: https://demos.telerik.com/kendo-ui/gantt/columns

1. Filter by "Title" -> contains "Market". Only the child "Market" will be visible in the parent "Research" task.
2. 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.

Delete Gantt dependency requires to click on it and press the delete key.

How can I delete it on a mobile device without a physical keyboard?

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

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 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

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.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@NeliKondova/arUgAguv
2. Click in the 'Task1' cell to edit and mark the entire text using the mouse
3. Type some text and press 'Enter' - The issue will not be replicated in case the edited mode is exited through clicking in another cell, but only by pressing Enter.
   screencast

Current behavior

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

Expected/desired behavior

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.
