Team,

Dojo ref : https://dojo.telerik.com/@Aswathi/uXoJoSUq 

When I edit the calendar value and click on any other row/cell it doesn't get saved. If I click outside it gets saved. I see it's due the property 

.

If we set it  editable:true , it's breaking the reorder functionality.

Is there a way to fix this ?

Appreciate your support.

Regards,

Sujith

Bug report

If you select a custom view in the Gantt and shrink the window so that a DropDownList would appear, the custom view does not appear as selected in the DropDownList.

Reproduction of the problem

1. Open this example - https://dojo.telerik.com/@martin.tabakov@progress.com/ECOhusOc
2. Shrink the browser until the DropDownList appears on the Gantt toolbar.
3. Select the Quaterly custom view.

Current behavior

Quaterly custom view is not displayed as the selected value of the DropDownList

Expected/desired behavior

Quaterly custom view should be displayed as the selected value of the DropDownList

Hi, 

I use a Gantt chart like this one. 

<script>
  $("#gantt").kendoGantt({
  dataSource: [{
    id: 1,
    orderId: 0,
    parentId: null,
    title: "Task1",
    start: new Date("2021/6/1"),
    end: new Date("2021/6/3")
  }],
  range: {
    start: new Date("2021/05/31"),
    end: new Date("2021/12/01")
  },
  views: ["month"]
});

In the example, the Gantt chart starts on May 31, 2021.
In the first header line we see the month of May, followed by July. There is no month of June.

https://dojo.telerik.com/@lydbell/ULAPUdOV

This only happens when the last day of the month is Monday .

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.

Hi!

For small tasks delete button overlaps a button for creating dependencies. How can we fix this behaviour?

Bug report

The menu that determines where to add new task incorrectly appears after creating a new task and editing an existing one.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/uBAHUgOy
2. Add new task.
3. Randomly edit another task so that no item is selected in the Gantt TreeList.
4. Press the Add Task button again.

Current behavior

The Add Child/Above/Below menu appears unexpectedly.

Expected/desired behavior

The menu should not appear and a new task should be added at the bottom of the list.

Bug report

When the validation message appears that the Start Date should be before the End Date, picking a proper End Date does not automatically remove the validation message in the Gantt.

Workaround: call the validate method in the change event of the End DatePicker.
https://dojo.telerik.com/@martin.tabakov@progress.com/IQiRukIN/11

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/@martin.tabakov@progress.com/IQiRukIN/10
2. Edit an existing task or create a new one.
3. In the Start DatePicker, choose a date that is after the EndDate, so that the validation message would appear.
4. Pick an EndDate that is after the StartDate.

Current behavior

The validation message remains and the user must again focus and blur the Start Date picker for the message to disappear.

Expected/desired behavior

The validation should be removed automatically after picking a EndDate that is after the StartDate.

Bug report

When tasks are reordered in Gantt duplicated requests are sent for updating.

Reproduction of the problem

1. Open the Gantt Overview Demo
2. Reorder two tasks and inspect the requests in the Network tab

Current behavior

For example, in case two tasks on the same level are changing their places, four requests are sent, two by two the requests are the same.
In case a task is moved on a different level multiple requests are sent, as all are duplicated.

Expected/desired behavior

There should be no duplicated requests when reordering tasks in Gantt

This is a regression introduced with R3 2020 (2020.3.915)

Bug report

If a date is configured in Gantt by using the date method or views.date configuration and then a task is edited, the Gantt displays the initial date after editing a task.

Reproduction of the problem

1. Open the Dojo
2. Scroll horizontally and edit a task (for example 'Architecture')

Current behavior

After the task is edited the horizontal scroll position is set to its initial position, not to a position according to the edited task. Thus, the user needs to scroll again in order to find the edited task.
The behavior is not the same when the date method/configuration is not used. Also, the behavior is not the same if we first switch between the 'Day', 'Week', 'Month' views before editing a task.

Expected/desired behavior

Even if the initial date of the Gantt is configured, when the user edits a task, the date should not be persisted. The horizontal scroll should be in the same position as before editing a task.

Bug report

When there are Grid and Gantt on the same page and a column in the Gantt has reordered an error in the console is thrown:
kendo.all.js:133531 Uncaught TypeError: Cannot read properties of undefined (reading 'lockable')

Reproduction of the problem

1. Open the Dojo. There is no relation in the configuration between the Grid and the Gantt widgets.
2. Reorder the columns in Gantt

Current behavior

The following error is thrown:
kendo.all.js:133531 Uncaught TypeError: Cannot read properties of undefined (reading 'lockable')

Expected/desired behavior

There should be no error in the console when reordering columns in Gantt, even if there is a Grid on the page.

The issue is a regression starting with: 2021.3.1207

Environment

• Kendo UI version: 2022.2.802
• Browser: [all]

As all grids, the kendo Gantt chart's rows change their color when hovering. However, the background overlaps the border between columns and makes them disappear for the hovered row.

You can reproduce the described behavior by hovering one of the rows in this DOJO.

Bug report

2. Open the Network Tab
3. Create a new task dependency

Current behavior

Two identical Create requests are sent to the server

Bug report

When there is a selected item and filtering is performed in the Gantt, sometimes a task in the new filter result is displayed as selected.

Reproduction of the problem

1. Open the demo - https://demos.telerik.com/kendo-ui/gantt/columns
2. Filter the tasks by ID 18
3. Select the task with ID = 18
4. Filter the tasks that have ID equal to 11

Current behavior

Sometimes the task with ID 11 is marked as selected. The issue does not appear consistently, so you may need to perform the test multiple times.
screencast - https://somup.com/c0XZ6DgaRA

Expected/desired behavior

The tasks that have not been selected, should not be displayed as selected after filtering.

The issue is a regression starting with the 2022 R1 release

Bug report

When the culture is changed the NumericTextBox with decimals does not accept valid values when it is rendered inside an editable popup. The issue can be observed when the NumericTextBox is rendered for editing in other components such as Gantt and Grid.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@gdenchev/UKAVAnaZ
2. Try to edit a cell and decrease the number either by entering digits or by using the arrows.

Current behavior

A validation error that the value is not valid appears.
The same behavior occurs in the Gantt component if you try to edit a task, then select Resources and try to edit the Units value - https://dojo.telerik.com/@NeliK/uZepIbId

Expected/desired behavior

The value of the NumericTextBox should accept changes when the culture is set.
