Hi there,

We are using Telerik kendo with ASP.net MVC. This request is specifically for the Gantt chart view as described here: https://demos.telerik.com/aspnet-mvc/gantt. Configuring the month, year and day view seems pretty easy via the exposed API. We want to extend this so that we can see the Gantt for custom date ranges. For example we should be able to click a button that says : Q1  and can see the Gantt for 3 months (Ex: Sep, Oct, Nov). Please note that this is different from filtering through selected dates. We want to the Gantt to display extended views. Feel free to let me know if I can provide any more clarity.

Thanks!

Describe the bug
When boostrap.min.css is loaded on the page, the positioning of the Gantt tasks within the task rows is incorrect. The task are not centered and start overlapping the next row. Additionally, misalignment between the rows in the timeline and the treelist appears.

To reproduce
Steps to reproduce the behavior:

https://dojo.telerik.com/AYeWOkIX

The misalignment increases with each next row, so it becomes more evident, if you scroll down the view.

Expected behavior
Tasks are centered within their row. Timeline and treelist rows are aligned.

Bug report

Regression introduced in R1 2021 SP1. Possibly related to #6597.

Reproduction of the problem

Reproducible in the Kendo UI for jQuery Overview demo, the MVC Overview demo, other demos, and in the attached sample project.
MVCGanttTest.zip

1. Run a demo or the project (the project requires a reference to Kendo.Mvc.dll to be added).
2. Open the dev tools Network tab.
3. Double click a child task in the Timeline view to edit it.
4. Modify the task's title, e.g., a character to the title text.
5. Save the task.

Current behavior

Multiple requests are sent to the Update action. One for the edited task and additional one(s) for the parent task(s) depending on the level of the edited task. This happens only on initial edit of that particular task. Subsequent editing results in only 1 request to the Update action.

Expected/desired behavior

Every time a task title is edited, only 1 request to the server should be sent.

Environment

• Kendo UI version: 2021.3.914
• jQuery version: x.y
• Browser: [all ]

Currently, each row in the Gantt is a separate task. Having the ability to display multiple tasks in the same row would be useful.

Currently the Gantt component provides support for single resource, where multiple units can be assigned to a Gantt task. It would be useful if the Gantt supports multiple resources, where multiple units of each resource can be assigned to the Gantt task.

Bug report

A regression introduced in R3 2020. The issue is reproducible when editing a child task in the treelist. It works as expected when the percentComplete value is set in the timeline.

Reproduction of the problem

Reproducible in the demo.

1. In the treelist, modify the % Complete value of a child task (e.g., Design UI)

Current behavior

The % Complete value of the parent task is not updated.

Expected/desired behavior

The % Complete value of the parent task is updated.

Environment

• Kendo UI version: 2021.1.119
• jQuery version: x.y
• Browser: [all]

I would love to see a feature added to the MVC Gantt control that would allow filtering tasks within the Gantt. Currently when we filter tasks in our Gantt using an external filter which filters the datasource tasks are dropped from the result set if their parent tasks do not meet the filter criteria. This is obviously a problem and makes filtering useless when tasks are dropped when they actually meet the criteria. I would like to see the filtering work as the TreeView and TreeList controls do. When you filter a column in those controls the parent items are returned regardless of whether they meet the filter criteria. This is needed in a hierarchical control like the Gantt chart.

This would be a great addition to the control. In the meantime, we'll either leave filtering out of our application or try to find a way to recursively gather all of the parent task ids and include them in our service to return tasks that meet the filter criteria.

Thanks for considering!

Hi,

 

I have developed an application where I am displaying records in kendo Gantt chart, Initially I want to display only title and give user the option to select start & end date.  This means that I need to pass null value for start & end date, but I could not find the option. Could you please help me with it.

Also I want to add validations for start date & end date i.e. if user does not enter start & end date an alert should be displayed specifying user to add dates.

Please let m know whether its possible or not & if possible how should I go ahead with it.

  

We are using the Gantt view to display the timeline of an operation which typically spans over 15-30 minutes.

As such we want to view the Gantt timeline by minutes, but we can only seem to get as far as hours.

How can we set the Gantt view to by minutes?
