Bug report

Grid throws an error when the Filterable Column Messages TagHelper is set.

Reproduction of the problem

  • Open the following Telerik REPL example.
  • Set the child <messages /> in a column's <filterable></filterable> TagHelper.
  • Notice the observed error.

Current behavior

Setting the Messages TagHelper produces the following compilation error:

The tag is not allowed by parent tag helper. Only child tags with name(s) 'cell, operators, datasource' are allowed.

Expected/desired behavior

Setting the Messages TagHelper should not produce the following compilation error.

Bug report

Group Paging is not working as expected when the Kendo UI Grid is populated from data deserialized from a file and multiple groups are defined.

Reproduction of the problem

Using the UI for ASP.NET Core Grid, populate it with a file, set GroupPaging to true, add more than one group, and set the default serialization:

 

builder.Services.AddControllersWithViews()
            .AddJsonOptions(options =>
                options.JsonSerializerOptions.PropertyNamingPolicy = null);
@(Html.Kendo().Grid<MyViewModel>()
        .Name("grid")
        .Groupable()
        .Scrollable(s=>s.Virtual(true))
        .DataSource(dataSource=>dataSource
            .Ajax() 
            .GroupPaging(true)
            .PageSize(50)
            .Read("ReadFromFile", "HomeController")
            .Group(x=>
            {
               x.Add(y=>y.Group1);
               x.Add(y=>y.Group2);
            })      
        )
        //...)

Current behavior

With multiple groups, the follow error message will appear:

System.ArgumentNullException: Value cannot be null. (Parameter 'source')

Expected/desired behavior

Server GroupPaging should work as expected with multiple groups and the default serialization that is delivered with ASP.NET Core. An example would be this live demo.

Workaround

Use the Newtonsoft library to set the serialization options for the application:

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

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

groupPaging is not compatible with the groupHeaderColumnTemplate

### Bug report

When the pageSizes option is enabled, it is not displayed when the Grid is initialized inside a hidden container.

### Reproduction of the problem

1) Follow the instructions in this KB article to display a Grid inside a TabStrip component.

2) Enable the "pageSizes" setting.

3) The drop-down, which allows the user to change the page size is always hidden.

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

The same example works correctly with version 2023.2.718.

### Expected/desired behavior

The pager must display the specified page sizes.

### Workaround

tabstrip.one("activate", function() {
  grid.pager._lastWidth = 30;
  grid.resize(true);
});

In Telerik UI for ASP.NET MVC you could put Grid options in the query string of the page with the grid name as a prefix and those would be automatically applied to the correct grid. This is achieved via the PrefixUrlParameters configuration, though it is missing for the ASP.NET Core Grid.

It would be useful to add this option to the ASP.NET Core Grid, as it will allow the configuration for multiline templates. For example:

I have noticed that neither the HtmlHelper nor the TagHelper wrappers of the Grid's Pageable.Pagesize configuration support the all option to be configured as a page size.

This is unlike the Kendo UI for jQuery pageSize option which supports it as per the example in the API:

When a Grid that has a DateTime column is exported to Excel that column doesn't get its width automatically like columns bound to other types of data.

An explicit Width needs to be set for the DateTime column as evident in this Telerik REPL.

Could you please fix the columns.autoWidth of the kendo.ooxml.Workbook to work for all types of data?

I am using the Grid with two editor template bound to viewdata to populate the components.

Now this is code that I wrote in 2017 that I recent upgraded to .NET 7 ASP Core and has work all those years with no issue. So I think this may be a regression in the grid code.

I have embedded the relevant code leaving out the grid views custom javascript since it isn't relevant.

The behavior that I am seen is that the the grids model properties that do NOT use a customer editor template are not being bound when the save event fires.

public class AlertRuleGridViewModel
{
    public int Id { get; set; }

    [UIHint("ComponentEditor")]
    public string? Component { get; set; }

    [UIHint("EmailAddress")]
    public string? Email { get; set; }

    [UIHint("TypeEditor")]
    public string? Type { get; set; }

    [UIHint("Boolean")]
    public bool Enabled { get; set; }
}

### Bug report

When the Grid group paging is enabled, and the Grid is grouped, when the user search through the built-in search panel, and expand a specified group, an infinite loop appears. The Grid sends Read requests, and the server returns empty "data" property.

### Reproduction of the problem

1) Create a Grid bound to remote data and enable the group paging feature.

2) Group the Grid by a specified column.

3) Enter a value in the Grid search panel (the grouped data is filtered).

4) Expand a specified group --> it causes an infinite loop.

5) Open the browser Network tab to review the Read requests.

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

### Expected/desired behavior

The grouped Grid data should be filtered through the search panel as expected.

### Environment

* **Kendo UI version: 2023.1.117
* **jQuery version: 1.12.4
* **Browser: [all]

Is it possible to add an option to enable/disable the valuePrimitive of the DropDownList editor of a Foreign Key column in the Grid? This way, the ForeignKey column can be configured to allow null values.
