Bug report

The dependencies in the Gantt can not be removed.

Reproduction of the problem

1. Open the demos - https://demos.telerik.com/kendo-ui/gantt/index
2. 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 ]

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!

The current list of events associated with PDF creation of Gantt chart data is insufficient. In order to make this control production suitable the following PDF generation events/features would be needed:

1.- Ability to provide progress on the PDF file generation. Right now this can take minutes.

2.- Ability to cancel a PDF generation that is in progress. Right now this is not possible, but would be needed for lengthy operations.

Currently % complete calcs for summary tasks are based solely on the sum of % complete per child task / number of child tasks (x%+y%+z%)/3.   In this way, a small scale task of 1 or 2 days has a large impact on summary % complete whereas a large task of 60 days has a small impact.  Request is to add in weighting based on duration (end date - start date).

It would be great to have multiple column sort in Gantt view 

I'd like to modify the line of tasks summary in the Gantt chart. We'd like to display the sub-tasks in the parent task line. We would like to be able to display multiple tasks (children) in a single line (the parent task).

Hi,

I am using kendo's Gantt chart. But I unable to achieve few things using the existing Gantt chart features.
Following are the features I request should be provided for Gantt chart:

1. Multiple tasks/milestones in a row.
2. Multiple rows for a parent task.
3. If space is not available in preceding row(s), overlapping tasks should be moved to next row.
4. User should be able to provide start date for the quarter in a fiscal calendar. Ex: If user give 01st-June as the start date, then Q1 should start from 01st-June. Hence, quarters will be defined as: Q1(June-Aug), Q2(Sept-Nov), Q3(Dec-Feb), Q4(Mar-May)

Refer above image for point 1-4

 

       5. If task label is exceeding the width of the task, then height of the task should be increased to accommodate task label(in other words, text should            be wrapped). Also, font-size of the text should be responsive, that is, font-size should be reduced to accommodate entire text in minimum task height.

Refer above image for point 5

 

That is for scenarios when the start of one task is dependent on the end of another task. In such a case, if the end of the initial task changes, the start of the dependent task should also change automatically.

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

Is it possible to set custom holidays in gantt like Windows version ?

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.

I'm interested in using the Gantt chart for a project scheduling application but I need a lot more customization on the look & feel than is currently available. For instance, being able to eliminate the secondary timescale bar under the primary so that if you're in, say, the month view there is no 'week' slots under it.

From the 2015.2 release to the 2015.3 release, the built-in validation on the Start date was removed from the left-hand treelist.  So now I can move the Start date to be after the Finish date, and the Gantt control responds by treating this as a "move".   However, there is still built-in validation on the Finish date so that I cannot move the Finish date to before the start.   I would expect the same behavior for changes in both directions.   If I change the Finish date to before the Start date, then this should also be treated as a "move", where the duration of the task is retained, and the Start is also moved back N days.

This is a trivial change to make.  I think it's removing 1 line of code.  And this would really help with usability for users who want to achieve a "move" action, but who prefer to edit their data using the left-hand treelist instead of the right-hand timeline.

Right now the Gantt marks the current day with a line.

It would be great if we could pass an array of objects with title, type and begin/end information, which would be marked on the timeline background in a similar way -- for example display holidays or context time information (when planning something in a larger context).

Does not need to be editable -- being able to override the color for each object would be nice

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"

Hour Span should be allowed integer values instead of only number values(currently it takes the floor of any decimal value)

To configure the component, I would like to be able to have and customize tooltips for the views when I am performing a resize or move on the tasks. I have looked through the documentation and all I could find one option called resizeTooltipFormat.

That is a problem for me because, first, it's only a format for the dates and not a full template, and second, there is no option to do the same for the move action.

Implement support for external editor in the Gantt. Instead of using an editor template or calling the editTask method, make possible Gantt tasks to be updated without opening the default editor.

A modification in a child task, e.g. changing its start date, should also update the summary task.
