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.

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!

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"

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.

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.

                    

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

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!

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

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?

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.

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.

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.

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

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.

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.
