Bug report

The DataSource's property groupPaging: true prevents the Grid's group from expanding if it has a defined groupHeaderColumnTemplate.

Reproduction of the problem

1. Open this Dojo
2. Try to expand the Grid's groups

Also reproducible in the Core wrapper where an error is thrown: kendo.all.js:8743 Uncaught TypeError: Cannot read property 'hasSubgroups' of undefined

Current behavior

groupPaging is not compatible with the groupHeaderColumnTemplate

Expected/desired behavior

groupPaging and the groupHeaderColumnTemplate should be compatible

Environment

• Kendo UI version: 2021.2.616

• Browser: [all]

Hey,

It would be very useful if the TimePicker component would have a feature called something like "AutoFocusTime()". By default, when there is no value inside the TimePicker, the default focused time is "12:00 am", therefore the user has to scroll up all the way to the required time. With the feature above, it would be possible to enter a time which should be focused by default. For example "8:00 am" which is when most businesses start operating.

Now the question is, why not just putting in a default value. Well, in a form with lots of inputs, the user may not know anymore which values he entered and which inputs have a default value set and therefore submitting wrong data. If a input doesn't have a default value this mistake can be caught by setting a [Required] attribute. Threfore, the user has to enter a value and it will be guaranteed that all values where entered by him and it wasn't a default value which has been set.

See ticket id 1412837.

Even when using server side paging some requests can be very long, and may be canceled by the user.  Adding a CancellationToken parameter to the ToDataSourceResultAsync.

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.

IgnoreCase property is missing for the filterable options of the column:

The option is documented in:

Currently, the functionality for creating a toolbar template with TagHelpers is not available. 

Provide editable AcroForms support in PDFViewer.

The current implementation of the Kendo PDFViewer depends on pdf.js, so the following should be taken into account:

I noticed that in version 2023.2.606 you introduced some Date Editing enhancements for the DateInput component, like:

• AutoSwitchParts
• AutoSwitchKeys
• AutoCorrectKeys
  etc.

but these options aren't available for other DatePickers that implement the DateInput internally:

@(Html.Kendo().DateTimePicker()
              .Name("datepicker")
              .DateInput()
)

As a result of an EF Core issue, the ToDataSourceResult() is not able to perform the query when the DataSourceRequest object contains grouping.

The problem occurs using the query below, assembled by Telerik routine:

var temp = _db.Pessoa
    .OrderBy(item => item.Email)
    .Skip(0)
    .Take(40)
    .GroupBy(item => item.Email)
    .OrderBy(g => g.Key)
    .Select(g => new AggregateFunctionsGroup
    {
        Key = g.Key,
        ItemCount = g.Count(),
        HasSubgroups = false,
        Member = "Email",
        AggregateFunctionsProjection = new
        {
            Count_Referencia = _db.Pessoa
                    .Select(t => new
                    {
                        t.IdPessoa,
                        t.Referencia,
                        t.Nome_RazaoSocial,
                        t.Apelido_Fantasia,
                        t.CPF_CNPJ,
                        t.RG_IE,
                        t.Email
                    })
                    .OrderBy(item => item.Email)
                    .Where(item => item.Email == g.Key)
                    .Count()
        },
        Items = g
    })
    .ToList();

In the routine where the AggregateFunctionsGroup is created, the Items property must not only be the query itself, but also the fields specified in the main Select. Or, the call to the Select() method must simply be added:

var temp = _db.Pessoa
    .OrderBy(item => item.Email)
    .Skip(0)
    .Take(40)
    .GroupBy(item => item.Email)
    .OrderBy(g => g.Key)
    .Select(g => new AggregateFunctionsGroup
    {
        Key = g.Key,
        ItemCount = g.Count(),
        HasSubgroups = false,
        Member = "Email",
        AggregateFunctionsProjection = new
        {
            Count_Referencia = _db.Pessoa
                    .Select(t => new
                    {
                        t.IdPessoa,
                        ...
                    })
                    .OrderBy(item => item.Email)
                    .Where(item => item.Email == g.Key)
                    .Count()
        },
        Items = g.Select(t => new
        {
            t.IdPessoa,
            ...
        })
    })
    .ToList();

This way, the issue does not occur.

I want to design a web page with text and signature input. In Tablet I need to enter the text fields and signature fields using touch pen. I want the web page to allow the touch pen to write comments and signature and save into database

Provide support for the asp-page-handler attribute to call a handler in an ASP.NET Core 2.1 Razor page in addition to supporting controller/action methods.

We have the need to create a chart to display Risk Information. Below is the image of a risk matrix as defined on pages 96 in AFPAM63-128 https://static.e-publishing.af.mil/production/1/saf_aq/publication/afpam63-128/afpam63-128.pdf -- there are more examples on page 101

Another example of a risk matrix can be seen on page 18 here -> https://static.e-publishing.af.mil/production/1/af_se/publication/afi90-802/afi90-802.pdf

I've copied the images here for convenience.

Would it be possible to add this to the Kendo Chart backlog?

If there is a text binding to the item that has a script tag injected, the Core component will break its initialization instead of encoding it as it is done for the Telerik UI for ASP.NET MVC DropDownList helper.

        @(Html.Kendo().DropDownList()
            .Name("DDL")
            .HtmlAttributes(new { style = "width:100%" })
            .OptionLabel("Select...")
            .DataTextField("text")
            .DataValueField("value")
            .Height(310)
            .BindTo(new List<object> {
                new { text = "Test", value = 0 },
                new { text = "<script>alert(123)</script>", value = 0 }
            })
        )

Result:

We want to have a tabstrip that a user can select the tabs that he wants with checkbox. For example:

It will be a great feature.

<div id="tabstrip">
      <ul>
             <li>@Html.Checkbox("name",false) A </li>
      </ul>
</div>
