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

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).

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

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

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.

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.

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

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.

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).

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.

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
   

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

We currently do not have an option for lazy loading in Gantt.

It will be helpful to have this option for large data (like 10000). 

We do currently have a filter functions like range to show the limited data but having loadOnDemand helps for large data.

Can create a template for parent task. Like we can create for child tasks.

Bug report

While editing a Gantt task name navigating in the input field with a mouse click does not work. Double-clicking on a cell enters edit mode and positions the cursor at the end of the text. Moving the cursor using the mouse does not work while navigating in the input field with the keyboard works.

Reproduction of the problem

1. Run this dojo
2. Double-click the title of the first task
3. Try to click elsewhere in the input field to move the cursor.

Current behavior

Clicking in the input field does not move the cursor to the selected position

Expected/desired behavior

Clicking in the input should move the cursor to the selected position

Environment

• Kendo UI version: 2019.2.619
• Browser: [all]

In the Gantt widget, columns can have a custom format, but not a custom template. I'd lie a template like grids and treelists have.

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

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!

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.
