UI for ASP.NET Core: How to call code from "Save" toolbar button?

I added a toolbar to my grid, with new, save and cancel buttons. On my page, I configure the datasource to use the save routine in my controller. However, any breakpoints set in my Save (update) routine are never hit, even after editing and saving the grid. Is there an event I should be capturing? Like all of my issues, this is after following an example on the Telerik site. My read method is working perfectly.

Index.cshtml

    <form class="form-inline">
        <div class="form-group mb-2">
            <label for="SievePack" class="sr-only">Choose a Sieve Set</label>

            <kendo-grid name="SievePack"
                        detail-template-id="template"
                        navigatable="true">
                <columns>
                    <column field="SieveSetId" title="Set ID" />
                    <column field="SieveSetName" title="Name" />
                </columns>
                <toolbar>
                    <toolbar-button name="create" ></toolbar-button>
                    <toolbar-button name="save"></toolbar-button>
                    <toolbar-button name="cancel"></toolbar-button>
                </toolbar>
                <datasource page="0" type="DataSourceTagHelperType.Custom" custom-type="odata" page-size="6" batch="true" >
                    <schema data="Data" total="Total" errors="Errors">
                    </schema>
                    <transport>
                        <read url="@Url.Action("ReadSieveSets", "SievePack")" datatype="json" />
                        <update url="@Url.Action("Sievesets_Update", "SievePack")" />
                        <create url="@Url.Action("Sievesets_Create", "SievePack")" />
                    </transport>
                </datasource>

                <editable mode="incell" />
            </kendo-grid>
        </div>

    </form>

and the controller:

        [HttpPost]
        public ActionResult Sievesets_Update([DataSourceRequest] DataSourceRequest request, [Bind(Prefix = "models")] IEnumerable<SieveSet> sets)
        {
            // Will keep the updated entities here. Used to return the result later.
            var entities = new List<SieveSet>();
            if (ModelState.IsValid)
            {
                using (_context)
                {
                    foreach (var set in sets)
                    {
                        // Create a new Product entity and set its properties from the posted ProductViewModel.
                        var entity = new SieveSet
                        {
                            SieveSetName = set.SieveSetName,
                            SieveSetId = set.SieveSetId
                        };
                        // Store the entity for later use.
                        entities.Add(entity);
                        // Attach the entity.
                        _context.Attach(entity);
                        // Change its state to Modified so Entity Framework can update the existing product instead of creating a new one.
                        _context.Entry(entity).State = EntityState.Modified;
                    }
                    // Update the entities in the database.
                    _context.SaveChanges();
                }
            }
            // Return the updated entities. Also return any validation errors.
            return Json(entities.ToDataSourceResult(request, ModelState, set => new SieveSet
            {
                SieveSetName = set.SieveSetName,
                SieveSetId = set.SieveSetId
            }));
        }

Cards not rendering properly on razor page

Hello,

I just copied some code for cards from this page:

https://docs.telerik.com/aspnet-core/knowledge-base/cards#styles

But the buttons on the cards, and the styles don't seem to be rendering properly. Are the cards not supported on the razor pages? I only see them in the main documentation page, not the razor docs page. Or am I missing something?

I attached an image showing what cards look like for me.

P.S: I have nothing on the page except for the code for cards:

@page
@model IndexModel

@inject Microsoft.AspNetCore.Antiforgery.IAntiforgery Xsrf
@Html.AntiForgeryToken()
@{
    ViewData["Title"] = "Home page";
}
<! -- ########## Pasted code for cards here ########## -->

using hiddenfor and textboxfor for the same field is not supported anymore

I have an application where in the past I used HiddenFor and TextBoxFor for the same field where the TextBoxFor was disabled.

@Html.HiddenFor(m => m.String)
@Html.Kendo().TextBoxFor(m => m.String).HtmlAttribute(new { @class = "k-state-disabled", disabled = "disabled" })

We are currently trying to upgrade our telerik to the latest version and found this issue.

What is the recommended way of fixing this.

The reason we need this is because the field is on a form and sometimes its disabled and the value needs to be submitted.

Changing labels on numeric filter

How do I change this numeric filter label to "Min:" and "Max:" ? Instead of From and To.

I tried this but it does not do anything:

 columns
                    .Bound(p => p.Total)
                    .Title("Total")
                    .Format("{0:C}")
                    .Filterable(ftb => ftb.Extra(true)
                    //.UI("currencyFilter")
                     .Operators(o => o.
                        ForNumber(n => n
                            .IsLessThanOrEqualTo("Min")
                            .IsGreaterThanOrEqualTo("Max")
                            )
                     ))
                    .Width(130);

The questions I have are:

Which model should be used in _ItemPartial.cshtml?
Is the code in Index.cshtml.cs correctly using the Item property?
Within the popup dialog, how should the Update button be wired?
