### Bug report

When the Gantt has a custom editor template, the Update request is not fired. When using the default editor template, the respective task is updated correctly. 

The last version, where this scenario works as expected, is 2023.1.117.

### Reproduction of the problem

1) Define an editable Gantt that binds to remote data.

2) Set up a custom editor by using the editable.template option.

3) Try to edit a Task in the Gantt timeline table. The editable model is marked as "dirty", but the "save" event does not fire and the Update request does not trigger:

However, when using the default Gantt editor, the request triggers as expected. 

A Dojo sample for reproduction: https://dojo.telerik.com/EyumevaD

### Expected/desired behavior

The tasks should be edited correctly when using a custom editor template.

### Environment

* **Kendo UI version: 2023.1.314

Bug report

Setting the sortable configuration for a Gantt column via TagHelpers does not enable sorting for the column.

Reproduction of the problem

1. Run the TagHelper Gantt Basic Usage demo - REPL
2. Try to sort a column, for example the Start column

Current behavior

Columns are not sorted.

Expected/desired behavior

When sorting is enabled for a column it should be sortable.

Workaround

Set the sortable configuration for the desired columns after initialization of the Gantt component - REPL

    $("document").ready(function(){
        var gantt = $("#gantt").getKendoGantt();
        var options = gantt.options;
        options.autoBind = true;
        options.columns[2].columns[0].sortable = true; //enable sorting for Start column
        options.columns[2].columns[1].sortable = true; //enable sorting for End column
        gantt.setOptions(options);
    })

Bug report

The Core wrapper does not have a "Type" option:

.DependenciesDataSource(d => d
	.Model(m =>
	{
		m.Id(f => f.DependencyID);
		m.PredecessorId(f => f.PredecessorID);
		m.SuccessorId(f => f.SuccessorID);
		**m.Type(f => f.Type);**
	})
	.Read("Read_Dependencies", "Gantt")
	.Create("Create_Dependency", "Gantt")
	.Destroy("Destroy_Dependency", "Gantt")
)

Both the MVC wrapper and the jQuery widget allow to specify a field in the data that will be used as "type". Currently the Core wrapper does not allow specifying a field, and dependencies will work only if the data contains a field named "Type".

Hello,

I have a Gantt that only can have two levels. I guess drag&drop is the best and easiest way to do this (Is it a better solution like editing the order value directly in the TreeList area?)

I want to implement order change in the following way. 

1. If user changes parent task order, he has to drag that parent task (A) and drop on another parent task (B). This way, task A will take task B order value (Shall task B take task A order?). If user drops parent task A on any child task, no order change will happen.
2. Drag of any child task only will be valid in the same parent. I mean, dropping child task in any parent task or in other parent child task will do nothing.

Could you send me any example of this behaviour?

Regards!

Bug report

The OrderId field for the Gantt tasks cannot be defined in its datasource using the UI for ASP.NET Core wrappers.

*for more details, please refer to ticket #1461758

Reproduction of the problem

Create a UI for ASP.NET Core project and try to initialize the Gantt component with a datasource configured similar to the following:

Current behavior

The marked "OrderID" definition is not a valid one in UI for ASP.NET Core

Expected/desired behavior

The datasource configuration provided above(or similar) should be valid for the Gantt component. The OrderID should be configurable using the ASP.NET Core wrappers.

Environment

• Kendo UI version: 2020.1.406
• jQuery version: x.y
• Browser: [all]

Bug report

In a Razor Pages project, the Gantt's tasks are not binding if the taskID and parentID fields are strings.

This is a regression introduced in version 2020.3.915.

Reproduction of the problem

1. Open and run this example
2. Switch to Kendo version after 2020.2.617

Current behavior

There are no tasks displayed in the Gantt.

Expected/desired behavior

The tasks should be displayed.
