Bug report

Reproduction of the problem

Reproducible in:
https://demos.telerik.com/aspnet-mvc/grid/editing-inline
and
https://demos.telerik.com/aspnet-core/grid/editing-inline

1. Put a row in edit mode.
2. Inspect the input in the ProductName column

Current behavior

The input does not have a title attribute or label.

Expected/desired behavior

The input should either have a title attribute, like in the Kendo UI for jQuery Grid, or since we use a TextBox component as editor in MVC and Core, a label should be rendered.

Environment

• Kendo UI version: 2021.2.616
• jQuery version: x.y
• Browser: [all]

Bug report

Reproduction of the problem

1. Set up a Grid to use server binding
2. Add a custom command:

columns.Command(command => command.Custom("View Email"))
	.Title("Body")
	.Width(150);

Current behavior

When the Grid is configured to use server binding, it will render an anchor element. If remote binding is used, the Grid will correctly render a button element.

Expected/desired behavior

Consistency in the rendering. A button element should be rendered, regardless of using server or remote binding.

Environment

• Kendo UI version: 2022.3.913
• jQuery version: x.y
• Browser: [all]

Bug report

When .Navigatable() is enabled, the Grid renders an aria-describedby attribute in each td element. The value of the attribute should match the id value of the respective column header. This works for standard columns bound to fields in the data, but doesn't work for a selectable column:

columns.Select();

The selectable column header element (th) does not render an id. The td elements of that column render an aria-describedby attribute, the value of which does not match any element id. This causes an accessibility issue (Ticket ID: 1530928).

Reproduction of the problem

Reproducible with the MVC helper:

@(Html.Kendo().Grid<TelerikMvcApp1.Models.OrderViewModel>()
	.Name("grid")
	.Columns(columns =>
	{
		columns.Select();
		columns.Bound(p => p.OrderID).Filterable(false);
		columns.Bound(p => p.Freight);
		columns.Bound(p => p.OrderDate).Format("{0:MM/dd/yyyy}");
		columns.Bound(p => p.ShipName);
		columns.Bound(p => p.ShipCity);
	})
	.Pageable()
	.Navigatable()
	.Scrollable()
	.HtmlAttributes(new { style = "height:550px;" })
	.DataSource(dataSource => dataSource
		.Ajax()
		.PageSize(20)
		.Read(read => read.Action("Orders_Read", "Grid"))
	)
)

Current behavior

The selectable column header element (th) does not render an id.

Expected/desired behavior

The selectable column header element (th) renders an id that matches the aria-describedby attribute value of the td elements in the column.

Environment

• Kendo UI version: 2021.2.616
• jQuery version: x.y
• Browser: [all ]

Not sure if this is already in the works but when building mvc grids it would be helpful to have the ability to prevent a column from getting too big when the screen size is larger than the grid needs. Right now if columns are turned off and there is more space for the unlocked columns, they expand to fill the page which is normally fine but in some instances it looks silly to have a column for example that you would enter a 2 digit number in to be 300 plus px wide.

Bug report

When the scrollable option is disabled, on resizing the browser window by making it more narrow, at certain point the columns stop resizing and the whole table goes out of the right border of the Grid. Reproducible with the SASS and LESS themes.

Reproduction of the problem

Dojo example: https://dojo.telerik.com/ItIrEzEY/3

1. Either resize the right pane or use Fullscreen and resize the browser window and make it narrower.

Current behavior

The table goes out of wrapping element (.k-grid).

Expected/desired behavior

The columns resize and the table remains within the borders of the Grid.

Environment

• Kendo UI version: 2023.1.117
• jQuery version: x.y
• Browser: [all]

Bug report

When the Grid AutoBind() configuration is set to false, the Grid is rendering an empty cell in the row element with class .k-no-data. (Image.png)

Reproduction of the problem

Set AutoBind configuration of Telerik UI for Asp.Net MVC Grid to 'false'. The Grid is rendered correctly except for the empty row and the empty cell in the table body.

Current behavior

An empty row with one empty cell is rendered.

Expected/desired behavior

The tbody element should be empty.

Reproduction of the problem

Reproducible in the demos: https://demos.telerik.com/aspnet-mvc/grid/persist-state

1. Inspect the rendering of the "Contact Name" header in the MVC and Kendo UI for jQuery demos.

Current behavior

The difference in the rendering is shown below. In the Kendo UI Grid's Html, there is a span with class "k-cell-inner" that wraps the ".k-link" span, whereas in the MVC Grid, only an anchor is rendered.

Kendo UI:

<th scope="col" role="columnheader" data-field="ContactName" aria-haspopup="true" rowspan="1" data-title="Contact Name" aria-label="Contact Name Press ctrl + space to group" data-index="0" id="a44eadd9-62c6-4154-9735-4351a9cb5064" class="k-header k-filterable" data-role="columnsorter" style="touch-action: none;">
  <span class="k-cell-inner">
    <span class="k-link">
      <span class="k-column-title">Contact Name</span>
    </span>
    <a class="k-header-column-menu" href="#" title="Contact Name edit column settings" aria-label="Contact Name edit column settings" tabindex="-1">
      <span class="k-icon k-i-more-vertical"></span>
    </a>
  </span>
</th>

MVC:

<th class="k-header k-filterable" data-field="ContactName" data-index="0" data-title="Contact Name" id="f28afe50-210a-474d-9943-113f6bd4ad15" scope="col" data-role="columnsorter" style="touch-action: none;">
  <a class="k-link" href="/aspnet-mvc/grid/persiststate_customers_read?grid-sort=ContactName-asc">Contact Name</a>
  <a class="k-header-column-menu" href="#" title="Contact Name edit column settings" aria-label="Contact Name edit column settings" tabindex="-1">
    <span class="k-icon k-i-more-vertical"></span>
  </a>
</th>

Expected/desired behavior

Identical rendering.

Thanks!

When using the Grid Endless Scrolling, is there a way to prevent the existing records from momentarily disappearing as the spinner appears?

Using endless scrolling on a large grid (full screen), the users eye tracks down the list as the mousewheel is turned. At the moment the next page is fetched, the view of the data is disrupted as the spinner appears and the data disappears. This can be quite jarring to the senses when browsing for a specific record in the list.

On a small grid such as that on the example page (https://demos.telerik.com/kendo-ui/grid/endless-scrolling-remote) it isn't quite as jarring on the senses, but with a large grid with many columns and rows, it can be very off-putting.

Ideally, if the existing records can remain opaquely visible in the background under the spinner whilst the next page of data is being retrieved, it would produce a much cleaner user experience.

Describe the bug
Column headers do not resize properly in IE11 when scrollable is set to false. Regression introduced in 2021.3.914.

To reproduce
Steps to reproduce the behavior:

1. Go to https://demos.telerik.com/kendo-ui/grid/selection-export?autoRun=true&theme=bootstrap-main

The column headers are squished to the left side.

Expected behavior
Columns headers must have the same width as the respective columns.

Workaround:

.k-ie .k-grid-header {
  display: table-header-group;
}

there seems to be a bug in your commands column and it's made worse when loading/saving grid layouts.

When i load a page with this grid column definition, 

.Groupable()
                    .Columns(columns =>
                    {
                        columns.Command(cmd => cmd.Custom("Undelete")
                            .Click("undelete"))
                            .Width(60);

when you inspect the grid, the grid internally shows two classes for the command cell:

attributes: {class: 'k-command-cell k-command-cell'}

now, if i apply a grid layout, the problem gets worse.  This sample code will cause the dom to end up with multiple k-command-cell classes on the grid's td element.

$("#UndeleteGrid").data("kendoGrid").setOptions($("#UndeleteGrid").data("kendoGrid").getOptions())

<td class="k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell" role="gridcell"><a role="button" class="k-button k-grid-Undelete" href="#" title="Undelete"><span class="k-icon k-i-undo"></span></a></td>

We set up a grid that auto-filters a name field to "does not contain" and the value it excludes is "[DEACTIVATED]".  This column is also filtering out records that have a null in them if this filter is set.  I had to change the datasource to return an empty string instead.

The NumericTextBox renders two input elements. In a Grid inline editing scenario: https://demos.telerik.com/aspnet-mvc/grid/editing-inline  one of inputs of the NumericTextBox editor does not render a title and there is no label for the inputs. This causes an error for missing form element label in Html static analysis (Wave).

One way for this to be avoided could be using aria-labelledby attribute instead of title. The same aria-labelledby value will be assigned to both inputs pointing to a span or div that contains the input value. This way both inputs will have label and won't trigger the missing label error.
