The DataSource's property groupPaging: true prevents the Grid's group from expanding if it has a defined groupHeaderColumnTemplate.
Also reproducible in the Core wrapper where an error is thrown: kendo.all.js:8743 Uncaught TypeError: Cannot read property 'hasSubgroups' of undefined
groupPaging is not compatible with the groupHeaderColumnTemplate
groupPaging and the groupHeaderColumnTemplate should be compatible

### 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);
});
### Environment
* **Kendo UI version: 2023.2.829
* **jQuery version: 1.12.4
* **Browser: [all]
When tabbing in a batch editable Grid cells do not enter edit mode.
This is a regression introduced with v 2023.2.606.
The corresponding Unit Price is focused, but an editor is not generated
The cell should enter edit mode, as with v2023.1.425 - dojo
Grid Filterable Button Title Message is not correctly serialized.
Set the Filterable.Messages.ButtonTitle() API Configuration as follows:
@(Html.Kendo().Grid<OrderViewModel>()
.Name("grid")
.Columns(columns =>
{
columns.Bound(p => p.OrderID).Filterable(false);
columns.Bound(p => p.Freight);
})
.Filterable(f => f.Messages(m => m.ButtonTitle("Filter")))
)
Hover the Filter Button Icon and notice that the buttonTitle message is applied instead.
The Filter ButtonTitle message shows its default message.
The Filter ButtonTitle should show the custom-provided message.
Grid PageSizes TagHelper attribute does not expose an IEnumerable overload
The Grid PageSizes TagHelper attribute exposes only an int[]
overload which prevents adding options such as "All".
In comparison to its HtmlHelper counterpart:
.Pageable(paging => paging.PageSizes(new object [] { 5, 10, 20, "All" }))
It would be a good idea to consider altering the page sizes to accept an IEnumerable overload.
The TagHelper Grid's TagHelper is not correctly serialized and cannot be used to export hidden columns.
<columns>
<column field="Discontinued" hidden="true">
<exportable enabled="true" />
</column>
</columns>
The Grid TagHelper does not export hidden columns if the exportable TagHelper is enabled identically to the Kendo UI for jQuery Grid column exportable option.
The Grid TagHelper should be able to export hidden columns if the exportable TagHelper is enabled identically to the Kendo UI for jQuery Grid column exportable option.
### Bug report
When dragging and dropping a row within the Grid, the DOM element of the drag handle receives duplicated classes and styles.
### Reproduction of the problem
1) Enable the Drag & Drop functionality of the Grid.
2) Drag and drop a row within the Grid.
3) Inspect the DOM element of the drag handle - it has multiple duplicated classes and styles:

The last checkbox selection is not disabled and allows all the columns to be removed if the menu options for the command column are explicitly set to false:
The last checkbox selection should be disabled without allowing all the columns to be removed if the menu options for the command column are explicitly set to false:
The following dojo depicts the aforementioned behavior.
Currently, the ASP.NET Core Grid Columns's Template() method does not expose the ability to provide a delegate. In comparison to the ASP.NET MVC Grid Column's Template() method:
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:
.Columns(columns =>
{
columns.Template(@<text>
<div>#= OrderID # </div>
<div>#= Discontinued # </div>
</text>);
})
The Columns.Template() method of the Grid does expose a delegate overload.
The Columns.Template() method of the Grid should expose a delegate overload.
Grouping a column with Group Paging and Client Operations enabled results in slow performance in comparison to prior versions.
The grouping functionality for the Grid with client operations and group paging would produce approximately 10 times slower results in terms of execution. In comparison to previous versions.
The grouping functionality for the Grid with client operations and group paging should produce identical time execution to prior versions, as illustrated in the following dojo.
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; }

public string? Component { 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]
When a Grid's row is reordered and then the changes are saved - a Destroy request is sent to the server for the dataItem of the reordered row. This happens even though no changes are applied to dataItem of the reordered row.
The Grid should request the reordered item to be perished from the backend.
In the latest version (2023.2.718), the Column Menu in the Grid faild to open if you set the Groupable option to false.
To reproduce the issue simply change the line below in the Grid Overview Demo
.Groupable(g=>g.ShowFooter(false))
to the following:
.Groupable(false)
https://netcorerepl.telerik.com/cxkhGOvU52pBO4NK33
The error you get when clicking on the Column Menu is:
Uncaught TypeError: Cannot read properties of undefined (reading '_canDrag') at init._updateGroupColumns (kendo.all.js:321370:19) at init._open (kendo.all.js:321370:19) at init.trigger (kendo.all.js:321370:19) at init._trigger (kendo.all.js:321370:19) at init.open (kendo.all.js:321370:19) at init.toggle (kendo.all.js:321370:19) at init._click (kendo.all.js:321370:19) at HTMLAnchorElement.dispatch (jquery.min.js:3:12445) at r.handle (jquery.min.js:3:9174)

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.
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);
})
)

Tooltip produces inconsistent behavior upon hovering when the content is configured through the content client-side configuration.
For every second hover, the Tooltip does not display the element's content.
For every second hover, the Tooltip should display the element's content.
If I put the Grid into a kendo-template for the TileLayout control, the ClientTemplate does not work properly. It only gets called once regardless of the number of items in the grid and the data is not being passed in.
This is my column definition:
columns.Bound(c => c.DocumentKey).Title(" ").ClientTemplate("#=CommandTemplate(data)#").Width(70);
And I am calling the .ToClientTemplate() on the Grid. Everything else work great except for this one issue.
I have not been able to find any other info, so what am I missing?
