### Bug report

When Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation NuGet package is installed in Telerik UI for ASP.NET Core application, it throws an exception:

FileNotFoundException: Could not load file or assembly 'Microsoft.DotNet.InternalAbstractions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.

### Reproduction of the problem

1. Create Telerik UI for ASP.NET Core MVC application (.NET Core version 6.0).

2. Install Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation NuGet package (version 6.0.5).

3. Turn on the Razor Runtime Compilation:

//Program.cs file

// Add services to the container.
builder.Services.AddControllersWithViews()
                .AddNewtonsoftJson(options => options.SerializerSettings.ContractResolver = new Newtonsoft.Json.Serialization.DefaultContractResolver())
                .AddRazorRuntimeCompilation();

4. Run the application and review the exception.

Attached is a runnable sample for reproduction.

### Workaround

Install Microsoft.DotNet.InternalAbstractions NuGet package (version: 1.0.0)

### Environment

* **Kendo UI version: 2022.2.510
* **jQuery version: 1.12.4
* **Browser: [all]

It would be useful to have a grid operator for "IN" conditions. Right now we only have 2 options for an OR without having to use a custom filtering and custom clearing functions.

We have a lot of data that needs to be filtered that is not sequential.  For example purposes:

Given that a customer has a standing purchase order for parts over time.

Given that serial numbers on said parts will not be sequential and may not be even be similar enough for wildcards (if that feature is provided.)

Given that we need to filter grid data to retrieve customer number, purchase order and a set of serial numbers, we need the equivalent of:

SELECT * FROM testdatatable WHERE customer = '#####' AND purchaseorder = '#####' AND serialnumber IN ('abciqwe', 'cid235', 'sn34087', 'hpk2679');

which would be WHERE WHERE customer = '#####' AND purchaseorder = '#####' AND (serialnumber  = 'abciqwe' OR serialnumber =  'cid235' OR serialnumber = 'sn34087' OR serialnumber 'hpk2679');

So basically I would like to have the ability to have multiple OR statements and the operand could be 'contains' or 'not contains' as that would probably work better than "equal".

Our immediate need is for the MaskedTextBox.

And have modified my program.cs to add:

// Add services to the container.

builder.Services.AddControllersWithViews()

                // Maintain property names during serialization. See:

                // https://github.com/aspnet/Announcements/issues/194

                .AddNewtonsoftJson(options => options.SerializerSettings.ContractResolver = new Newtonsoft.Json.Serialization.DefaultContractResolver());

// Add Kendo UI services to the services container"

builder.Services.AddKendo();

I copied the code from your demo into the ASP.net 6.0 Page above.

I added data properties to the Index.cshtml.cs model and changed the Value property on each Kendo object to point them. That works fine

The issue is that the formatting is not applied:

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" />

Bug report

When using th-TH culture and setting a valid name for a component an exception InvalidOperationException: Name cannot contain spaces. is thrown.

Reproduction of the problem

Sample Application

1. Run the attached application
2. Select th-TH from the DropDownList, to change the culture

Current behavior

An InvalidOperationException: Name cannot contain spaces. is thrown.

Expected/desired behavior

Exception should not be thrown and components should be rendered as expected.

Environment

• Kendo UI version: 2022.1.119
• Browser: [all]

Hi,

Will the TagCloud control from the ASP.NET AJAX package ever be ported to the ASP.NET Core package?

I use this on faculty profiles and it is a required component if I ever want to move them to Core.

Thanks,

Charlotte McClellan

There is a new CheckBoxTagHelper to support the new rendering, but the public ModelExpression For { get; set; } property is missing.

Steps to reproduce

1. Execute the code below
2. Enter some values in the Html and Kendo inputs
3. Hit the browser's back button
4. Hit the browser's forward button to redisplay the page

Current Behavior

The value in the Html Input is restored but not the value of the Kendo Input. The same behavior applies for Kendo NumericTextBox, etc.

<!DOCTYPE html>
<html>
  <head>
    <link rel="stylesheet" href="https://kendo.cdn.telerik.com/2021.3.1207/styles/kendo.bootstrap-v4.min.css" />
    <script src="https://kendo.cdn.telerik.com/2021.3.1207/js/jquery.min.js"></script>
    <script src="https://kendo.cdn.telerik.com/2021.3.1207/js/kendo.all.min.js"></script>
    <script src="https://kendo.cdn.telerik.com/2021.3.1207/js/kendo.aspnetmvc.min.js"></script>
  </head>
  <body>
    <form>
 
      <div>
        <label for="HtmlInput">Html Input</label>
        <input type="text" id="HtmlInput" name="HtmlInput">
      </div>
 
      <div>
        <label for="KendoInput">Kendo Input</label>
        @(Html.Kendo().TextBox ().Name ("KendoInput"))
      </div>
 
    </form>
  </body>
</html>

If you use "Edit in REPL" button in any demo that uses `kendoConsole.log()`, it will throw an error that the kendoConsole doesn't exist (you can use the Upload > Events demo as a quick example).

This is happening because the kendoConsole is only a part of demos.telerik.com pages that does not get copied over to the REPL or Dojo because it is irrelevant to the demo itself. The fix is to change all kendoConsole.log() instances to console.log()

That said, I am opening this bug report so that the dev team can consider ways to handle the "edit in" scenarios.

Thank you,

Arthur

### Bug report

The localization script "kendo.messages.en-GB.min.js" throws a type error in the browser console - "Cannot read properties of undefined (reading 'messages')".

### Reproduction of the problem

1. Include the culture script "kendo.culture.en-GB.min.js" on the page (locally or by using the Kendo CDN service).

2. Include the localization script "kendo.messages.en-GB.min.js" (locally or by using the Kendo CDN service).

3. Set the culture to "en-GB".

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>

Bug report

The DatePicker's popup has a CSS min-height property set that causes it to sometimes have an empty blank space at the bottom.

Reproduction of the problem

1. Open the DatePicker Demo
2. Expand the monthpicker

Review another occurence.

Expected/desired behavior

There should be a blank space in the DatePicker's popup.

Environment

• Kendo UI version: 2021.3.914
• Browser: [all]

Kendo dialog structure doesn’t use Aria landmarks properly for buttons  - this leads to a validation error

The pager control's select box renders role="listitem" but the parent is missing role="list"  - this leads to a validation error

Listviews will render role="list" even when empty - this leads to a validation error

Kendo grids use 2 tables (one for header and one for the data) which means that there are no role="cell" assigned to any of the headers  - this leads to a validation error

Scrollable grids are missing a tabindex="0" to allow for keyboard navigation - this leads to a validation error

this form doesn't have Core 2, 2.1, 3.0, 3.1 or 5 in the .Net Framework drop down. Just gonna pick 4.8 even though it doesn't apply. I am using core 5.

Hi Telerik Team

Wil younot implement the LightBox also as a a asp.net core component ? 


We think it will be usefull. of course we could also implement in window component but its not the same

Bug report

A DataSource defined using TagHelpers with disabled serverPaging sets default pageSize:

    <datasource type="DataSourceTagHelperType.Ajax" server-filtering="true" server-paging="false">
            <transport>
                <read url="@Url.Page("Index", "Read")" data="forgeryToken" />
            </transport>
            <schema data="Data">
                <model id="OrderID">
                    <fields>
                        <field name="ShipName" type="string"></field>
                    </fields>
                </model>              
            </schema>
     </datasource>

generates the following initialization script:

{"dataSource":{"page":1,"pageSize":20,"schema":{"model":{"id":"OrderID","fields":{"ShipName":{"type":"string"}}},"data":"Data","errors":"Errors","total":"Total"},"serverAggregates":true,"serverFiltering":true,"serverGrouping":true,"serverPaging":true,"serverSorting":true,"transport":{"read":{"url":"/?handler=Read","data":forgeryToken}},"type":(function(){if(kendo.data.transports['aspnetmvc-ajax']){return 'aspnetmvc-ajax';} else{throw new Error('The kendo.aspnetmvc.min.js script is not included.');}})()}

with default pageSIze set.
Initializing using jQuery works as expected:

       dataSource: {
            type: "aspnetmvc-ajax",
            serverPaging: false,
            serverFiltering:true,
            transport: {
                read: {
                    url: "@Url.Page("Index", "Read")",
                    data: forgeryToken
                }
            },
            schema: {
                model: {
                    id:"OrderID"
                },
                data: "Data",
                total:"Total"
            }
        }

Current behavior

The "page" and "pageSize" values are set, which results in only 20 items being displayed, even though more are returned by the "read" action.

Expected/desired behavior

The "page" and "pageSize" should not be set.

Environment

• Kendo UI version: 2021.1.330
• Browser: [all]

Issue

Using any overload of ToDataSourceResult(Async) with a DataSourceRequest containing filter descriptors on an IQueryable provided by Entity Framework core 2.x, causes Entity Framework's "Query cache" to fill up for different filter values, leaking memory in the process. This is caused by using Expression.Constant in the generated expression trees for a DataSourceRequest's FilterDescriptors. Refer to https://github.com/dotnet/efcore/issues/14859 for more details about why this leaks memory.

Since Entity Framework's cache is always missed for new filter values, performance is also degraded due to this issue.

The issue is not present when using Entity Framework core 3 or greater. Apparently using Expression.Constant is not an issue on these version.

I have attached a minimal working example that illustrates the memory leak.

Fix

This issue can be fixed by changing FilterDescriptorExpressionBuilder.CreateValueExpression to not return a ConstantExpression, but a MemberExpression instead. Entity Framework 2.x will correctly parameterize the MemberExpression, causing the query cache to be hit correctly for queries that only differ in parameter values. It won't parameterize ConstantExpressions. Refer to https://stackoverflow.com/a/60516780/147993 for an example of generating a MemberExpression instead of a ConstantExpression.
