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.

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

I would like to multi-select some tasks in a level and use keyboard delete button and delete all of them.

Problem: We really want to fit Gantt's on particular paper sizes (def. landscape A3); however, using the paperSize option doesn't really work as the output (font size, row heights, etc.) end up being too big and not suitable.

And for the majority of the time, paperSize set to auto creates an output (font size mostly) too small.

Rock and a hard place... 

Solution 1: When pdf.paperSize is not set to auto i.e. A3, A4, etc. Allow a percentage scaling to be set, ideally individually, on X and Y.

Solution 2: Scale fonts and scale timeline on X axis maintaining taskList width.

Ultimately, get a large plan to fit on landscape A3.

Incorporate page breaks into the Gantt PDF Export and include option to repeat column headers on each page.

Add a way to highlight the critical path in the Gantt Chart. This is a basic feature in project management and would be really great if you can implement,.

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

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.

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.

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

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.

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.

In the Gantt control there should be events for expand/collapse to provide things like on-demand loading of subnodes for large project-trees

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.

We would like you add capability to Gantt chart control to handle time zones of the browsers. Currently, when Gantt chart control renders in browsers based in different time zones, it displays event start date/end date differently in each time zone no matter where the source code of the web application resides.

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.

Add undo/redo to Kendo UI Gantt Chart Control using keyboard shortcuts ctrl-z and ctrl-y

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

Allow storing a deadline in a Gantt Task. This could be used to visualise deadlines as you can in Telerik's Silverlight Gantt chart: http://demos.telerik.com/silverlight/#GanttView/Deadline,
or it could be used to figure out which tasks to highlight that are late, overdue or on the critical path.
