Hi Sergi0,

This can be achieved using a custom editor template. I would recommend checking this demo as well as our offline demos, which are located in the Kendo UI installation path, under the \wrappers\aspnetmvc\Examples directory.

Hi,
I have some problem with adding child item when using DropDownList in editor template.
When i add new item (level 0) to TreeList via toolbar all is OK.
When i try to addChild (level 1) - click on column button and i got chrome console error:
Uncaught ReferenceError: Company is not defined
 
Error in Code:
 
(function(data
/**/) {
var o,e=kendo.htmlEncode;with(data){o=''+e(Company.CompanyName)+'';}return o;
})

Events before error and after click on Add child button:
TreeList data binding
TreeList data bound
TreeList data binding
TreeList data bound
TreeList data binding


My View:
@model LaborTreeViewModel
@{
    ViewBag.Title = "Test";
    Layout = "~/Views/Shared/_contLayout.cshtml";
}
 
<h2>Test</h2>
@using Cont.Web.Models.Forms
@using Kendo.Mvc.UI
 
<div class="demo-section k-header">
    @(Html.Kendo().TreeList<LaborTreeViewModel>()
        .Name("treelist")
                .Toolbar(toolbar => toolbar.Create().Text("Create"))
        .Selectable(true)
        .Columns(columns =>
        {
            columns.Add().Field(e => e.WBS);
            columns.Add().Field(e => e.Name).Width(220).Title("Наименование");
             
            columns.Add().Field(e => e.PlanDateStart).Format("{0:MMMM d, yyyy}");
            columns.Add().Field(e => e.PlanDateEnd).Format("{0:MMMM d, yyyy}");
            columns.Add().Field(e => e.Company).Template("#:Company.CompanyName#");
            columns.Add().Field(e => e.Responsible).Template("#:Responsible.ResponsibleName#");
             
 
 
            columns.Add().Width(200).Command(c =>
            {
                c.Edit();
                c.CreateChild();
            })
            .HtmlAttributes(new
            {
                style = "text-align: center;"
            });
        })
            .Editable()
            .Filterable()
        .DataSource(dataSource => dataSource
                    .Create(create => create.Action("Create", "EmployeeDirectory"))
                    .Read(read => read.Action("All", "EmployeeDirectory"))
                    .Update(update => update.Action("Update", "EmployeeDirectory"))
                    .Destroy(delete => delete.Action("Destroy", "EmployeeDirectory"))
 
                    .Model(m =>
                    {
                        m.Id(f => f.Id);
                        m.ParentId(f => f.ParentLaborId);
                        m.Field(f => f.Name).DefaultValue("Новая работа");
                        m.Field(f => f.PlanDateEnd);
                        m.Field(f => f.PlanDateStart);
                        m.Field(p => p.Company).DefaultValue(ViewData["defaultCompany"] as CompanyViewModel);
                        m.Field(p => p.Responsible).DefaultValue(ViewData["defaultResponsible"] as ResponsibleViewModel);
                    })
                    .ServerOperation(false)
 
        )
 
 
        .Events(events =>
        {
            events.Edit("onEdit");
            events.Save("onSave");
            events.Remove("onRemove");
            events.DataBinding("onDataBinding");
            events.DataBound("onDataBound");
            events.FilterMenuInit("onFilterMenuInit");
            events.Change("onChangeRow");
        })
 
        .Height(540)
 
    )
</div>
<script>
    var debugging = false;
    function onEdit(arg) {
        var model = arg.model;
 
        console.log("TreeList edit: " + model.FirstName + " " + model.LastName);
    }
 
    function onSave(arg) {
        //debugger;
        console.log("TreeList save");
    }
 
    function onRemove(arg) {
        console.log("TreeList remove");
    }
 
    function onDataBound(arg) {
        console.log("TreeList data bound");
    }
 
    function onDataBinding(arg) {
 
        console.log("TreeList data binding");
    }
    function onFilterMenuInit(arg) {
        console.log("TreeList onFilterMenuInit");
    }
    function onChangeRow(arg) {
        console.log("TreeList onChangeRow");
    }
     
</script>

If i commented fields Company and Responsible child then adding is OK.

Why did it happen?

Hi Sergi0,

It looks like the complex objects Company and Responsible do not exist in the child items. I would suggest verifying if that is indeed the case and if necessary - use a null check in the template. For example: 
#=data.NoSuchField ? data.NoSuchField : ''#"

Hi Alexander,
I replaced my templates to:

columns.Add().Field(e => e.Company).Template("#=typeof(Company)!='undefined' ? Company.CompanyName:''#");
columns.Add().Field(e => e.Responsible).Template("#=typeof(Responsible)!='undefined' ?Responsible.ResponsibleName:''#");

And this works)
Why older version template works with "new item" and does not work with "add child item"?

Hello Sergi0,

I investigated further and seems that this is caused by an incorrect behavior in the creation of child items. Basically, all children should inherit the defaultValues specified in the TreeList's DataSource, however that is not the case at this point, so I have logged an issue in our internal bug tracking system.

As a small sign of our appreciation for bringing this to our attention I have updated your Telerik points.
