Help with autocomplete for incell editing

I am attempting to use the autocomplete for incell editing. I have been searching and followed several examples but I can't get my code to work. When I select the cell, the current value deletes and the "working" spinner shows but no suggestions are listed.

Below is the code for the Grid, AutoComplete, and Controller function.

Index

@(Html.Kendo().Grid<Timecard.Models.TimecardViewModel>()

.Name("timecard")

.ToolBar(toolbar => toolbar.Create().Text("ADD").HtmlAttributes(new { title = "Add employee" }))

.Editable(editable => editable.Mode(GridEditMode.InCell))

.Columns(columns =>

{

columns.Bound(p => p.EmployeeName).Width(170).EditorTemplateName("_InCellAutoCompleteEditor");

columns.Bound(p => p.MonST).Filterable(false).Sortable(false).Format("{0:n1}").Title("Mon ST");

columns.Bound(p => p.MonOT).Filterable(false).Sortable(false);

columns.Bound(p => p.MonDT).Filterable(false).Sortable(false);

columns.Bound(p => p.TueST).Filterable(false).Sortable(false);

columns.Bound(p => p.TueOT).Filterable(false).Sortable(false);

columns.Bound(p => p.TueDT).Filterable(false).Sortable(false);

columns.Bound(p => p.WedST).Filterable(false).Sortable(false);

columns.Bound(p => p.WedOT).Filterable(false).Sortable(false);

columns.Bound(p => p.WedDT).Filterable(false).Sortable(false);

columns.Bound(p => p.ThuST).Filterable(false).Sortable(false);

columns.Bound(p => p.ThuOT).Filterable(false).Sortable(false);

columns.Bound(p => p.ThuDT).Filterable(false).Sortable(false);

columns.Bound(p => p.FriST).Filterable(false).Sortable(false);

columns.Bound(p => p.FriOT).Filterable(false).Sortable(false);

columns.Bound(p => p.FriDT).Filterable(false).Sortable(false);

columns.Command(command =>

{

command.Edit().UpdateText("Save");

command.Destroy().HtmlAttributes(new { title = "Delete highlighted employee" });

}).Title("Options").Width(150);

})

.Sortable()

.Scrollable()

.Filterable()

.Selectable(selectable => selectable

.Mode(GridSelectionMode.Single)

.Type(GridSelectionType.Cell)

)

.HtmlAttributes(new { style = "height:650px;width:1580px;" })

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(100)

.Model(model => model.Id(p => p.EmployeeCode))

.Read(read => read.Action("Employee_Read", "Timecard"))

.Create(create => create.Action("Employee_Create", "Employee"))

.Destroy(destroy => destroy.Action("Employee_Delete", "Employee"))

)

_InCellAutoCompleteEditor

@(Html.Kendo().AutoComplete()

.Name("EmployeeName")

.Filter("startswith")

.DataTextField("employeeName")

.ValuePrimitive(true)

.Placeholder("Select...")

.DataSource(source =>

{

source.Read(read =>

{

read.Action("Employee_Read", "Timecard");

})

.ServerFiltering(false);

})

)

TimecardController

public ActionResult Employee_Read([DataSourceRequest]DataSourceRequest request)

{

DataTable dt = new DataTable();

using (SqlConnection conn = new SqlConnection("Server={IPAddress};DataBase={DB};Integrated Security=SSPI"))

{

using (SqlCommand cmd = new SqlCommand())

{

cmd.CommandText = "uspEmployeeGet";

cmd.CommandType = System.Data.CommandType.StoredProcedure;

cmd.Connection = conn;

conn.Open();

dt.Load(cmd.ExecuteReader());

}

var dsResult = dt.ToDataSourceResult(request);

return Json(dsResult);

}

Disable fields in Popup edit conditionally based on Model field

Hi,

We have many models that we have set up Grids for and are using custom templates for the Popup editor. We wish to disable all of the fields in the Popup editor based on a boolean Model property, but were quick to find that the Razor Model object is not available in the custom template. We need to check this boolean property on a record by record basis (some records will be allowed for editing and some will not). I have taken a look at some of the solutions here and it seems that one approach is to create an on edit handler that manually disables all of the fields on the editor on an edit action. However this creates a serious overhead because it would mean we have to create this function for every grid. We have many different grids and they all have varying fields.

I was wondering if it is somehow possible to get access to this Model boolean property in the custom template and disable the fields as appropriate. Please note that we need to still be able to see the fields and their respective values and not hide/show the fields.

Command in first Column

In my ASP.NET Core 2.2 MVC project have the following TreeList control. This works. However, I prefer that the "Details" command go in the first column. However, when I do that... the hierarchy no longer works. It lists the items in the datasource but it doesn't indent anything. So 2 questions:

How do I put the Details command in the first column and keep the hierarchy working?
How do I change how far the hierarchy indents each child node? To me, what I have right now is too close.

Thanks in advance for your help,

Joel

I've been searching all over the Internet for an answer to this question, but to no avail. How do I set a default value for a NumberTextBoxFor HtmlHelper? I've seen examples where it's done by something similar to this: .HtmlAttributes(new { @Value = "9"}). However, this doesn't for for me. Any help is appreciated. Thanks.
