IHtmlHelper does not contain definition for Kendo .NET 7

I am using AspNet Core MVC 7

I am trying to create a custom HTML helper outside of a razor view. I am using the IHtmlHelper in this scenario and unfortunately outside of a razor view I cannot do something like this:

var uploader = _helper.Kendo().Upload()
                .Name("uploadFiles")
                .Multiple(true)
                .HtmlAttributes(new { style = "margin: 15px 0 5px 0;" });

Compilation error:

Error CS1061 'IHtmlHelper' does not contain a definition for'Kendo'

and no accessible extension method 'Kendo' accepting a first argument of

type'IHtmlHelper' could be found (are you missing a using directive or an assembly reference?)

Grid Setup

Good morning,

i need to save column sorting and other filters within a grid.

The only method i figured out is this:

I save the current grid state to the browser local storage

$(window).on("beforeunload", function () {

               var GType = '@Model.flowCatalogId' + '@Model.flowTypeCatalogId' + '@Model.filterVersion' + '@ViewBag.Lang' + '_grid_filtered';
            var grid = $("#grid_filtered").data("kendoGrid");
               localStorage["QSW-grid-Claim-List" + GType] = utf8_to_b64(kendo.stringify(grid.getOptions()));

         })

Then i reload it every time i enter the page at the end of it's load

$(document).ready(function () {

        $('body').css('pointer-events', 'all') //activate all pointer-events on body
        $('#dialog_pos').data("kendoDialog").close();
        $('#dialog_pos_supp').data("kendoDialog").close();
        $('#dialog_create').data("kendoDialog").close();

        var GType = '@Model.flowCatalogId' + '@Model.flowTypeCatalogId' + '@Model.filterVersion' + '@ViewBag.Lang' + '_grid_filtered';
        var grid = $("#grid_filtered").data("kendoGrid");

        if (localStorage["QSW-grid-Claim-List" + GType]) {
            var options = b64_to_utf8(localStorage["QSW-grid-Claim-List" + GType]);
            grid.setOptions(JSON.parse(options));
        }
        else
        {
            for (i = 0; i < localStorage.length; i++) {
                x = localStorage.key(i);
                if (x.includes("QSW")) { localStorage.removeItem(x);}
            }
        }

        $('#btnCreate').click(function (e) {
            $(this).prop('disabled', true);
            $('#create_form').submit();
        });


    });

This works but it do the read function of my grid 2 times.

.Read(read => read.Action("Claims_Read_Filtered", "Claim", new { flowCatalogId = Model.flowCatalogId, flowTypeCatalogId = Model.flowTypeCatalogId, Model.DateFrom, Model.DateTo})

My question is, how can i save the state of the grid with all of its filters and the column sorting and all the eventual changes i've done to it without run the read a second time?

Column editor with opportunities to add new record and select from existing ones

I need an editor for the field of text type. This editor when is activated should show two buttons. When the first button with the plus icon is clicked, an input appears in which a new value is typed. When the button with a colon is clicked, a dropdown appears from which an existing value is selected.

How to show html in grid client detail template

My template is

```

<script id="template" type="text/kendo-impl">
<div>
<partial name="EditorTemplates/WorkingEmployeeEditorTemplate"/>
<div style="margin: 15px; display: inline-block;">
@(Html.Kendo().Button()
.Name("createButton")
.Content("Add")
// .Events(e => { e.Click("create"); })
 )
</div>
</div>
</script>

```

It should have the dropdown and button in one row. When I rerun the page with this template, the grid disappears.

Is there a way to show a word count in or around the message box?

Hello,

I'm using an internal API that has rate and size limiting and I think it would be beneficial to show the user a used character out of total characters placeholder. Something similar to this as an example.

ASP.NET Core Scheduler problem with the UI of the Scheduler, when trying to display 15 mins events

Hi,

using Telerik Asp Net Core version 2022.2.621

I have a problem with the UI of the Scheduler, when trying to display 15 mins events. The widget contains typically 30 mins to 1 hour events, occasionally, there are 15 mins events, in which case after the 15 mins event the next event is pushed to the right. How to prevent that kind of behavior without changing the Major Ticks configuration.

Changing the Major Ticks configuration will cause a problem in the UI because normal classes are 1 hour length.
