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);
    })
    //....
)

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?

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
});

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

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

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.

Would you be able to implement a more visual aspect for the FileManagement so it look close to this picture.

Attach is the modified Kendo.all.min.js file that you may want to alter so it becomes a permanent in you repository. Changes made for those following :

* Changed:
  *     template:
  *     var i
  *     singleFileTemplate

The style sheet for the effects:

/* 5.7.3 - Filemanager Image Grid View */
.FileManagerImgGridView {
    display: flex;
    justify-content: start;
    align-items: center;
    gap: 10px;
    cursor: zoom-in;
}

    .FileManagerImgDownloadLink a {
        text-decoration: none;
        color: var(--bs-primary-inverted);
    }

also here is the C# Thumbnail Class that can be modified if you intend to have you own fabrication of thumbnail as it use to be years ago :-)

using SixLabors.ImageSharp;
using SixLabors.ImageSharp.Processing;

public virtual IActionResult Thumbnail(string path)
    {
        var virtualPath = Path.Combine(_thumbnailFolderRoot);
        var physicalPath = Path.Combine(ConstantVar.webEnv.WebRootPath, virtualPath.Replace('/', '\\'));
        path = Path.Combine(physicalPath, path);
        FileInfo imageInfo = new FileInfo(path);

        int width = 75;
        int height = 75;
        bool KeepRatio = true;

        using (Image image = Image.Load(imageInfo.FullName))
        {

            // Figure out the ratio
            double ratioX = (double)width / (double)image.Width;
            double ratioY = (double)height / (double)image.Height;
            // use whichever multiplier is smaller
            double ratio = ratioX < ratioY ? ratioX : ratioY;

            int newHeight = height;
            int newWidth = width;

            if (KeepRatio)
            {
                // now we can get the new height and width
                newHeight = Convert.ToInt32(image.Height * ratio);
                newWidth = Convert.ToInt32(image.Width * ratio);
            }

            image.Mutate(s => s.Resize(width: newWidth, height: newHeight));
            using (var ms = new MemoryStream())
            {
                image.SaveAsJpeg(ms);
                return File(ms.ToArray(), "image/jpg");
            }
        }
    }

 When uncheck "Use localization" while create project the Localization resources are still auto copied while publish the project.

The resources are part of the telerik.ui.for.aspnet.core.yyyy.q.mmdd.nupkg and therefore are copied to the bin folder regardless of the  "Use localization" option. The "Use localization" option controls the availability only of the messages files.

This a feature request for providing another lightweight NuGet which does not contain the localization dlls that could be used for non-localized projects.

At this stage, the Serialize() method depends on Newtonsoft.Json:

using Newtonsoft.Json;

namespace Kendo.Mvc.Infrastructure
{
    public class DefaultJavaScriptSerializer : IJavaScriptSerializer
    {
        public string Serialize(object value)
        {
            return JsonConvert.SerializeObject(value).Replace(@"<", @"\u003c").Replace(@">", @"\u003e");
        }
    }
}

Is it possible to remove the dependency and use the System.Text.Json serializer instead?

### 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);
}

### Environment

* **Telerik UI for ASP.NET Core version: 2023.3.1114
* **Browser:** [all]

### 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>

### Environment

* **Kendo UI version: 2023.2.606
* **jQuery version: 3.4.1
* **Browser: [all]

Dears,

While browsing the new components of UI for Asp Core, I found an Issue in the provided online sample (https://demos.telerik.com/aspnet-core/ripplecontainer/index)

After transferring and moving items between the lists of "RIPPLE ON LIST ITEMS", the list display the raw HTML of the items. So, I provided a screen record reproducing the issue (https://pasteboard.co/I7Fx0AW.gif).

When both UI for ASP.NET MVC and UI for ASP.NET Core Visual Studio extensions are installed and only UI for ASP.NET Core project is loaded, the notification for new version is shown for UI for ASP.NET MVC.

When trying to install Microsoft.VisualStudio.Web.CodeGeneration.Design 7.0.4 NuGet package in a Telerik UI for ASP.NET Core 2022.3.1109 application, it throws an exception:

NU1107: Version conflict detected for Microsoft.CodeAnalysis.CSharp.Workspaces. Install/reference Microsoft.CodeAnalysis.CSharp.Workspaces 4.4.0 directly to 
project TelerikAspNetCoreApp3 to resolve this issue. 

### Reproduction of the problem

1) Create a Telerik UI for ASP.NET Core 2022.3.1109 application (.NET 7.0).

2) Install Microsoft.VisualStudio.Web.CodeGeneration.Design NuGet package (version 7.0.4).

3) Review the NuGet Error in the output.

### Workaround

Install the the following NuGet packages:

• Microsoft.CodeAnalysis.Common
• Microsoft.CodeAnalysis.Workspaces.Common
• Microsoft.CodeAnalysis.CSharp
• Microsoft.CodeAnalysis.CSharp.Workspaces
• Microsoft.CodeAnalysis.VisualBasic
• Microsoft.CodeAnalysis.VisualBasic.Workspaces

Alternatively, install an older version of the Microsoft.VisualStudio.Web.CodeGeneration.Design package.

### Environment

* **Telerik UI for ASP.NET Core version: 2022.3.1109
* **.NET version: 7

I know you can query the client side JavaScript version using 

kendo.version

It would be handy if you could query the dll assembly version or cdn url so the URLs can automatically match the dll used in the solution especially when nuget is used to update it currently I work around this using:

    @{  var version = typeof(Kendo.Mvc.KendoServices).Assembly.GetName().Version;
        string kendoCDN = $"//kendo.cdn.telerik.com/{version.Major}.{version.Minor}.{version.Build}";}
    <link href="@Url.Content(kendoCDN + "/styles/kendo.bootstrap-v4.min.css")" rel="stylesheet" type="text/css" />
