Support TreeList incell editing with drag and drop

Ticket 1349649

Reproduction of the problem

editable: { 
   move:true,
   mode: "incell"
}

Edit a cell and click to another cell. The changed value will be lost.

Current behavior

The draggable functionality prevents the mousedown event. As a result, the change event of the editor input does not fire, which in turn prevents the MVVM from saving the updated value.

Expected/desired behavior

It would be great to have the ability to use both of these features together. Perhaps by wiring a drag event handler internally and dealing with any changes before dragging.

Workaround

Add an event handler to the cellClose event and trigger change programmatically to any inputs with the data-bind attribute as well as to any widgets:

            cellClose: function(e) {
              var input = e.container.find("input[data-bind*='value']");
              input.trigger("change");
              var numeric = input.data("kendoNumericTextBox");
              if(numeric){
                numeric.trigger("change");
              }
            }

Environment

• Kendo UI version: 2018.3.1017

We can evaluate an ignore option to the user events similar to draggable:

Added a note about the current limitation to the TreeList documentation here based on customer feedback:
https://docs.telerik.com/kendo-ui/controls/data-management/treelist/editing

If the problem is resolved, we should remove the note.

DevExpress's TreeList widget gets around this issue by adding a special left-most column where the user can click/tap for drag-and-drop operations. All the other columns can still allow in-cell editing. I think you guys should consider a similar option.
