Bug report

When the Columns.Command.Edit.UpdateText property is set to Update, the text will not be modified and will remain as the default value Save.

Reproduction of the problem

@(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.ProductViewModel>()
    .Name("grid")
    .Columns(columns =>
    {
        columns.Command(command => { 
            command.Edit().UpdateText("Update");  //Will not work
        }).Width(250);
    })
    //....
)

REPL
https://netcorerepl.telerik.com/wIuyvtcO41rAa82G36

Expected/desired behavior

The text should change to the specified content within UpdateText.

Workaround

Set the text via JavaScript using the setOptions method and columns.command.text:

        $(document).ready(function(){
            var grid = $("#grid").data("kendoGrid");
            var options = grid.getOptions();
            //set the text for the first command in the last column
            // as shown in the second example on:
            //https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/columns.command#columnscommandtext
            options.columns[4].command[0].text = { edit: "Edit", update: "Update" };
            grid.setOptions(options);
        });

Hi this is a pretty basic bug. But I am using the k-i-cancel icon class but for some reason it is showing the settings icon?

I have an editable kendo grid in which I have a date field. When I choose a date through the calendar for example: 26.12.2021 on post the model binder parses the date correctly.

If I manually enter the date in the cell the model binder parses the date as it was not an UTC and since my time zone is +2h it comes in the controller as 25.12.2021 22:00

(see the attached files)

 

Inside my startup.cs I have defined JsonOptions like this:

.AddNewtonsoftJson(options =>
                {
                    options.SerializerSettings.ContractResolver = new DefaultContractResolver();
                    options.SerializerSettings.DateTimeZoneHandling = DateTimeZoneHandling.Utc;
                });

 

In the Configure method:

var supportedCultures = new[] { new CultureInfo("bg-BG") };

app.UseRequestLocalization(new RequestLocalizationOptions
{
         DefaultRequestCulture = new RequestCulture("bg-BG"),
         SupportedCultures = supportedCultures,
         SupportedUICultures = supportedCultures
});

Layout.cshtml

<script src="~/lib/kendo/js/cultures/kendo.culture.bg-BG.min.js"></script>

<script>
        kendo.culture("bg-BG");
</script>

When i try to install the Telerik.UI.for.AspNet.Core library with the 2024.1.130 release number, it refuses to install due to downgrades of core microsoft codeanalysis packages.  This version of telerik is dependent on on the beta release number 4.8.0-3.final and is a downgrade from what is native to Visual Studio. It's being a huge pain to upgrade to install these downgrades.  Can you please update without beta dependencies?

This is a strange bug I came across when making a simple grid for a small personal project. I created a class called Book, which looks like this:

[Table("Books")]
    public class Book
    {
        [Key]
        public int Id { get; set; }
        [Required]
        public string Title { get; set; } = null!;

        public Checkout? Checkout { get; set; }

        [NotMapped]
        public bool CheckedOut => Checkout != null;
    }

I then created a simple Razor view on which to show the books on a grid. Here is what the code for the page looks like:

@{
    ViewData["Title"] = "All Books";
}

@(
    Html.Kendo().Grid<LibraryMvc.Core.Entities.Book>()
        .Name("bookGrid")
        .Pageable(p => {
            p.PageSizes(new[] {20, 50, 100 });
            p.Numeric(true);
            p.Input(true);
        })
        .Editable(e => e.Mode(GridEditMode.InLine))
        .Filterable()
        .Sortable()
        .Scrollable()
        .ToolBar(t => t.Create())
        .Columns(col => {
            col.Bound(c => c.Id).Title("ID");
            col.Bound(c => c.Title).Title("Title");
            col.Bound(c => c.CheckedOut).Title("Checked Out");
            col.Command(com => {
                com.Edit();
                com.Destroy();
            }).Title("Manage");
        })
        .DataSource(ds => 
            ds.Ajax()
            .PageSize(20)
            .Model(md => {
                md.Id(f => f.Id);
                md.Field(f => f.Id).Editable(false);
                md.Field(f => f.CheckedOut).Editable(false);
            })
            .Read(r => r.Action("Book_Read", "Book"))
            .Create(c => c.Action("Book_Create", "Book"))
            .Update(c => c.Action("Book_Update", "Book"))
            .Destroy(c => c.Action("Book_Destroy", "Book"))
        )
)

When running my app with this code, I noticed that client-side validation would not work on the grid. Nothing would stop me from adding multiple Book rows with empty Titles, despite Title being a [Required] property based on my Book class's Data Annotations:

I assumed I did something wrong, so I scoured the internet and Telerik's support items in hopes of finding something, but then I came across this when inspecting the page's elements in Chrome's dev tools:

Look at the script tag. For whatever reason, the kendoTextBox ended up using the Razor view's ViewData["Title"] property. Oops!

To work around this, I ended up changing my Book class's Title field to BookTitle, as shown below:

[Table("Books")]
    public class Book
    {
        [Key]
        public int Id { get; set; }
        [Required]
        [Column("Title")]
        public string BookTitle { get; set; } = null!;

        public Checkout? Checkout { get; set; }

        [NotMapped]
        public bool CheckedOut => Checkout != null;
    }

With this property name changed, I was able to get client-side validation to work as needed:

A second workaround involved getting rid of the ViewData["Title"] definition on my Razor view:

Given all this, it looks like something that's generating the client-side validation on the page is getting tripped up over the word "Title" being used by multiple items on the page.

### Bug report

When the deferred scripts are created, the script source points at the root of the application instead of the application's root directory.

### Reproduction of the problem

Enable the global deferred initialization and call the @(Html.Kendo().DeferredScriptFile()) method.

The rendered script tag is:  <script src="/kendo-deferred-scripts-XXXX.js"></script>

But it must be: <script src="/MyWebsite/kendo-deferred-scripts-XXXX.js"></script>

### Solution:

If you add a tilde in the Url.Content(), the generated script file must be located as expected:

public HtmlString DeferredScriptFile(string nonce = "")
{
           ...
            var scriptResult= hasDeferredScritps ? $@"<script src=""{urlHelper.Content("~/kendo-deferred-scripts-" + guid + ".js")}"" {(string.IsNullOrEmpty(nonce) ? "" : "nonce=" + '"' + nonce + '"')}></script>" : "";
            var styleResult = hasDeferredStyles ? $@"<link href=""{urlHelper.Content("~/kendo-deferred-styles-" + guid + ".css")}"" {(string.IsNullOrEmpty(nonce) ? "" : "nonce=" + '"' + nonce + '"')} rel=""stylesheet""></link>" : "";
            return new HtmlString(scriptResult + System.Environment.NewLine + styleResult);
}

### Bug report

When the Dialog is configured with actions and the Content Security Policy is enabled, it throws an "Invalid template" error.

### Reproduction of the problem

1) Configure a Dialog widget with actions and set the CSP with the following content:

<meta http-equiv="Content-Security-Policy" content="script-src 'self' 'unsafe-inline' https://kendo.cdn.telerik.com https://code.jquery.com; style-src 'self' 'unsafe-inline' https://kendo.cdn.telerik.com;" />

2) Open the browser console to review the error.

A Dojo sample for reproduction: https://dojo.telerik.com/ULOyazUC

### Expected/desired behavior

The Dialog should be rendered correctly without using the 'unsafe-eval' keyword in the "script-src" directive.

### Workaround

Insert the following script before the Dialog initialization:

 <script>
    kendo.ui.Dialog.fn._mergeTextWithOptions = function(action) { var text = action.text; if(text) { return kendo.isFunction(text) ? text(this.options) : text; } return ""; }
</script>

As per the subject, if you use jQuery to get a Kendo TabStrip in a ComboBox change event it inserts this div into the TabStrip control:

<div class="k-tabstrip-items-wrapper k-hstack">
    <ul class="k-tabstrip-items k-reset" role="tablist"></ul>
</div>

This used to work as we were changing the selected tab in a TabStrip based on a ComboBox selection, but this no longer works. Please see the following REPL where a new div is added every time you change the ComboBox value:

In the ThemeBuilder the controls do not use the latest version.

For instance while playing around with the ThemeBuilder I noticed that the primary button does not look primary like on the demos page.

Also it would be helpful to provide a page where you explain where every color is used.
