Hi Team,

Bug Report

The Kendo UI Grid's toolbar with a template is not persisted when the Grid is loaded using setOptions. 

Reproduction of the problem

With a toolbar containing a template with server tags, the toolbar content will disappear.

Expected Behavior

The Grid should retain the toolbar with the HTML contained when using setOptions.

Environment

Kendo UI version: 2022.2.510
jQuery version: all
Browser: all

Thanks!

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!

Bug report

The Kendo UI Grid's Toolbar Template UI for ASP.NET MVC documentation displays an approach used for UI for ASP.NET Core. The ClientTemplate and ClientTemplateID are not available for UI for ASP.NET MVC.

Reproduction of the problem

Please try the approach used in the documentation. It is not available for UI for ASP.NET MVC.

Expected/desired behavior

Either include the approach for UI for ASP.NET MVC, or modify the documentation.

Environment

• Kendo UI version: 2022.2.510
• jQuery version: 3.6
• Browser: all

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

Reproducible with a Grid nested in the content of the tab, or loaded in the tab through AJAX.

Reproduction of the problem

Dojo example: https://dojo.telerik.com/eJuHaTan

1. Select Tab1, or click the button above the TabStrip to select the tab programmatically.
2. Try to reorder a row in the Grid in Tab1.

Current behavior

The rows cannot be reordered.

Expected/desired behavior

The rows can be reordered.

Environment

• Kendo UI version: 2022.1.412
• jQuery version: x.y
• Browser: [all]

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.

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.

When using template and no DataSource is set Grid NoRecords message is not rendered.

Reproduction of the problem

Define a 'No Records' with template similar to the following article example: https://docs.telerik.com/aspnet-mvc/html-helpers/data-management/grid/templates/no-records

@(Html.Kendo().Grid<Grid_Template.Controllers.GridModel>()
    .Name("Grid1")
    .NoRecords(n => n.Template("string HTML template, not centered"))
)

Current behavior

The default message for missing record is displayed: No records available.
"autoBind":false is applied to serialization

Expected/desired behavior

The message from the template is displayed: "string HTML template, not centered"

Workaround:
Add .DataSource(d => d.Ajax()) to the Grid configuration

@(Html.Kendo().Grid<Grid_Template.Controllers.GridModel>()
    .Name("Grid1")
    .NoRecords(n => n.Template("string HTML template, not centered"))
        .DataSource(d => d.Ajax())

)
