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.

Hi Team,

I'd like to request a similar example based on the virtualization of local data demo for UI for ASP.NET MVC.  

Thank you!

Bug report

Reproduction of the problem

Dojo example: https://dojo.telerik.com/InUYAheR/4
Drag and drop a row from Grid2 to Grid1 by following the steps below:

1. Click and hold down the mouse button within a Grid2 row, just before its ID value or a little after it.
2. Drag the row to Grid1 and drop it over row 3 or row 4.

Current behavior

Grid1's first row values get updated, instead of the drop target row values. This is because e.target in the DropTarget's "drop" event does not return the actual target you drop over.
If you click and drag in the middle of the Grid2 row, drag it and drop it over a row in Grid1, the drag and drop functionality works as expected: e.target returns the correct target.

Expected/desired behavior

e.target should consistently return the target you drop over, regardless of where in the dragged row you have clicked.

Bug report

In the Less themes the textboxes and the other editors (e.g., NumericTextBox) in the popup of the Grid are misaligned. The rendering of the textboxes in the MVC and Core Grid is different when compared to the Kendo UI for jQuery Grid.

Reproduction of the problem

Reproducible in the Popup Editing demos (Core and MVC).

1. Click the "Edit" button in a random row.
2. Inspect the Product Name Textbox in the browser

Current behavior

The width of the TextBox does not match the width of the NumericTextBox.

The rendering differs:

<span class="k-widget k-textbox k-valid" style=""><input data-val="true" data-val-required="The Product name field is required." id="ProductName" name="ProductName" value="" data-role="textbox" aria-disabled="false" class="k-input k-valid" autocomplete="off" data-bind="value:ProductName" style="width: 100%;"></span>

vs

<input type="text" id="ProductName" name="ProductName" title="Product Name" required="required" autocomplete="off" data-bind="value:ProductName" class="k-textbox k-valid">

Expected/desired behavior

Identical rendering and alignment.

Environment

• Kendo UI version: 2021.2.511

Hi Team,

I would like to request better integration when grouping using a viewModel.  When grouping by defining the field in the group event using a model from EF, the Grid should continue to use the viewModel instead of the model's field.   This would provide the Grid's group templates to be retained. 

Please take a look at the following gif which shows the current behavior using the viewModel's RoomLocation field vs. the model's HomeRoom.RoomLocation. 

Thank you! 

Hi Team,

I'd like to request adding aggregation to the Kendo UI Grid Custom Ajax Binding Live Demo.

Thank you!

Implement stacking columns on smaller screens, e.g., https://docs.telerik.com/devtools/aspnet-ajax/knowledge-base/grid-stack-responsive-columns-on-small-screens

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

I've been using the "Change" event to handle a Single Row Selection grid as that seems to be the event to use to determine when the user selects a row.

I just tried adding "persistSelection(true)" to my grid but it seems to be triggering a change event when I switch to another page and back to the previous page, or do an external $(this).data('kendoGrid').dataSource.read() on the grid.

How can I only get a change event when the USER selects a row, not the persistedSelection selecting the row?

Or at least detetect where it came from it in my Change event?

Thanks,

Bryan

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.

It would be great if we could use the built in column filtering on columns containing arrays.

Or at the very least have a workaround (which I have not been able to find on the site).

I understand that the current implementation relies on the data being flat, but support for the following situation would be great:

- Grid cell is bound to an array and a template is used to display character delimited data (ie. One, two, three, four).

- Column filtering will display multi select options for the data.

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.

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>
