### Bug report
When there is an initially hidden column in the Grid with multi-column headers, the hiding/showing of columns through the ColumnMenu does not work correctly.
### Reproduction of the problem
1) Hide a column in the Grid with the Hidden(true) option.
2) Hide a column through the Grid column menu.
3) The header of the column that is hidden is added to the previous visible column.
4) Show the same column through the column menu - it does not render back as expected.
The issue is caused by the a mismatch in the column group header rendering:
- Group header:
- aria-haspopup="dialog" is missing;
- data-title="{group name}" is missing;
- the title in the group header must be rendered as:
<span class="k-cell-inner"><span class="k-link"><span class="k-column-title">Product Information</span></span></span>- Header:
- aria-haspopup="menu" is missing;
### Environment
* **Telerik UI for ASP.NET MVC version 2024.2.514
Bug report
There are multiple differences in the theme files. In the theme file added by the NuGet browser-specific styles are missing and calc values differ. Likely the issue is due to autoprefixer and postcss-calc being used in the kendo-themes repo: https://github.com/telerik/kendo-themes/blob/develop/postcss.config.js
and not being used in theme compilation logic in the kendo repo:
https://github.com/telerik/kendo/blob/production/gulpfile.js#L55C38-L55C39
https://github.com/telerik/kendo/blob/master/build/gulp/sass.js
Reproduction of the problem
- In an ASP.NET MVC app install the Telerik.UI.for.AspNet.Mvc NuGet package.
- The NuGet package adds the kendo theme files to the MyApp\Content\kendo\2024.2.514
- Open the classic-silver.css file added by the NuGet package and compare it to the file hosted on the CDN: https://kendo.cdn.telerik.com/themes/8.0.1/classic/classic-silver.css
Current behavior
There are multiple differences similar to the exemplary ones posted below:
Example 1:
CDN line 33994:
.k-menu-vertical > .k-menu-item > .k-menu-link > .k-menu-expand-arrow {
margin-inline-start: var(--kendo-spacing-2, 0.5rem);
margin-inline-end: calc(var(--kendo-spacing-2, 0.5rem)*2*-1 + -16px - var(--kendo-spacing-2, 0.5rem)/2*-1);
}
NuGet:
.k-menu-vertical > .k-menu-item > .k-menu-link > .k-menu-expand-arrow {
margin-inline-start: var(--kendo-spacing-2, 0.5rem);
margin-inline-end: calc( -1 * (calc( var(--kendo-spacing-2, 0.5rem) * 2 + 16px) - var(--kendo-spacing-2, 0.5rem)/2));
}
Note the difference in the margin-inline-end value.
Example 2:
CDN line 36510:
.k-progressbar-vertical .k-progress-status {
-ms-writing-mode: tb-lr;
writing-mode: vertical-lr;
}
NuGet:
.k-progressbar-vertical .k-progress-status {
writing-mode: vertical-lr;
}
Expected/desired behavior
The theme files distributed through CDN and NuGet should be identical.
Environment

Bug report
Reproduction of the problem
- Initialize a Grid with the following Filter and ColumnMenu configuration:
@(Html.Kendo().Grid<TelerikMvcApp1.Models.OrderViewModel>()
.Name("grid")
.Columns(columns => {
columns.Bound(p => p.OrderID).Filterable(false).Width(100);
columns.Bound(p => p.ShipCity).Width(100);
columns.Bound(p => p.ShipCity).Width(150);
columns.Bound(p => p.OrderDate).Format("{0:MM/dd/yyyy}").Width(140);
})
.Sortable()
.Filterable(f => f.Extra(true)
.Messages(message => message.Equals("Равно"))
.Messages(message => message.Filter("Приложи"))
.Messages(message => message.Clear("Изчисти"))
.Messages(message => message.Info("Покажи записи които:"))
.Messages(message => message.And("и"))
.Messages(message => message.Or("или"))
.Messages(message => message.AdditionalOperator("fdfdfd"))
.Messages(message => message.IsFalse("Активни "))
.Messages(message => message.IsTrue("Неактивни "))
)
.ColumnMenu()
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Model(model => model.Id(p => p.OrderID))
.Read(read => read.Action("Orders_Read", "Grid"))
)
)
Or use this REPL example: https://netcorerepl.telerik.com/QSYflePv05yaqnLZ07
The issue is also reproducible with the ColumnMenu set the following way:
.ColumnMenu(cm => cm
.Messages(message => message.Columns("Колони"))
.Messages(message => message.ColumnSettings("Насторйки"))
.Messages(message => message.Filter("Филтър"))
.Messages(message => message.SortAscending("Сортирай възходящ ред"))
.Messages(message => message.SortDescending("Сортирай низходящ ред"))
)
Current behavior
The filter menu messages are not set.
Expected/desired behavior
The filter menu messages are set regardless of whether a ColumnMenu is enabled or not.
Environment

### Bug report
When the Grid uses an external DataSource, the aggregates are undefined within the ClientGroupFooterTemplate().
### Reproduction of the problem
Use the following REPL sample that demonstrates the issue:
https://netcorerepl.telerik.com/mIkyQnvB382bsiFt24
1. Group the Grid by the "Freight" column.
2. An error is thrown in the browser console: "Uncaught ReferenceError: sum is not defined".
3. The aggregates=["sum"] is missing in the column options in the Grid initialization script;
"columns":[{"title":"Order ID","field":"OrderID","filterable":false,"encoded":true},{"title":"Freight","groupFooterTemplate":"Sum: #=sum#","field":"Freight","filterable":{"messages":{"title":"Show items with value that"},"checkAll":false},"encoded":true},{"title":"Ship City","width":"150px","field":"ShipCity","filterable":{"messages":{"title":"Show items with value that"},"checkAll":false},"encoded":true}]When the DataSource is defined within the Grid configuration, the aggregate is displayed as expected.
### Expected/desired behavior
The "sum" aggregate must be displayed within the group footer template of the column when the Grid is grouped.
### Workaround
Define the DataSource in the Grid configuration or update the Grid settings by using the setOptions() method when the page is loaded:
<script>
$(document).ready(function () {
var grid = $("#grid").data("kendoGrid");
if (grid) {
let gridColumns = grid.columns;
if (!gridColumns[1].aggregates) { // update [1] with the index of the column that has a group footer template. For example, "1" is the 2nd Grid column
gridColumns[1].aggregates = ["sum"];
grid.setOptions({ columns: gridColumns });
}
}
});
</script>### Environment

Bug report
A hidden template column that is not included in the ColumnMenu appears after showing another column
Reproduction of the problem
- Use the following declaration for the columns:
.Columns(columns =>
{
//Hidden template column
columns.Template(x =>
{
int rptIndex = Model.IndexOf(x);
string namePrefix = "Grid[" + rptIndex + "].";
Html.Hidden(namePrefix + "Id", x.Id, new { @readonly = "readonly" });
Html.Hidden(namePrefix + "Name", x.Name, new { @readonly = "readonly" });
}).Hidden().IncludeInMenu(false);
columns.Bound(x => x.Id).Width(120).Hidden(true);
columns.Bound(x => x.Name).Width(200);
columns.Bound(x => x.ReportingDateOriginal).Width(500).HtmlAttributes(new { id = "reporting-date-original" })
.Filterable(f => f.UI(GridFilterUIRole.DateTimePicker).Cell(c => c.Template("dateFilter")));
columns.Bound(x => x.Test1).Width(200).Hidden(true);
columns.Bound(x => x.TimezoneOffset).Width(200).HtmlAttributes(new { id = "reporting-date-offset" });
columns.Bound(x => x.Test2).Width(200).Hidden(true);
columns.Bound(x => x.ReportingDateAdjusted).Width(500).HtmlAttributes(new { id = "reporting-date-adjusted" })
.Filterable(f => f.UI(GridFilterUIRole.DateTimePicker).Cell(c => c.Template("dateFilter")));
columns.Bound(x => x.Test3).Width(200);
columns.Bound(x => x.Test4).Width(200).Hidden(true);
columns.Bound(x => x.Test5).Width(200);
})
- Show the Id column
Current behavior
The first time instead of the Id, the template column appears.
Expected/desired behavior
The Id column should appear and the template column should remain hidden.

Bug report
The rendering (structure and order of elements) of the th element of a column, for which a HeaderTemplate is set, does not match the Kendo UI Grid's rendering in a similar scenario. Prerequisites: HeaderTemplate, Sortable, Filterable enabled. For more context, see Ticket ID: 1639834.
Reproduction of the problem
Check the rendering of the header of the second column:
@(Html.Kendo().Grid<TelerikMvcApp1.Models.OrderViewModel>()
.Name("grid2")
.Columns(columns => {
columns.Bound(p => p.OrderID).Filterable(false).Width(100);
columns.Bound(p => p.Freight).HeaderTemplate("<span class='k-link'>My Template</span>");
columns.Bound(p => p.OrderDate).Format("{0:MM/dd/yyyy}").Width(140);
columns.Bound(p => p.ShipName);
columns.Bound(p => p.ShipCity).Width(150);
})

)
Current behavior
The content of the th is the following:
<a aria-hidden="true" class="k-grid-filter-menu k-grid-header-menu">
...
</a>
<span class="k-link">
...
</span>
Expected/desired behavior
The th content should be rendered as follows:
<span class='k-cell-inner'>
<span class='k-link'>
...
</span>
<a aria-hidden='true' class='k-grid-filter-menu k-grid-header-menu'>
...

Bug report
Regression introduced in R3 2023 SP1
If an initially hidden column is shown with the showColumn API method, the column header remains hidden because of the k-hidden class that remains in the th element.
Reproduction of the problem
- Click on the button above the Grid in the example below
<input type="button" name="btn1" value="Show the hidden columns" onclick="btn1Click()" />
<br />
<br />
@(Html.Kendo().Grid<TelerikMvcApp1.Models.OrderViewModel>()
.Name("Grid")
.Columns(columns =>
{
columns.Bound(p => p.OrderID);
columns.Bound(p => p.Freight);
columns.Bound(p => p.ShipName);
columns.Bound(p => p.ShipCity).Hidden(true);
columns.Bound(p => p.OrderDate).Format("{0:MM/dd/yyyy}").Hidden(true);
})
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Read(read => read.Action("Orders_Read", "Grid"))
)
)
<script>
function btn1Click() {
var grid = $("#Grid").data("kendoGrid");
grid.showColumn("ShipCity");
grid.showColumn("OrderDate");
}
</script>
Current behavior
The hidden columns are shown but their headers remain hidden.
As a workaround, the k-hidden class can be removed from the column header, after showing the column:
grid.showColumn("ShipCity");
$(".k-grid .k-header[data-field='ShipCity']").removeClass("k-hidden");
Expected/desired behavior
The columns and their headers are shown.

Prerequisites: reordering a non-locked column before a locked column. There could be one or more locked columns.
This behavior appeared in v2021.3.1207.
Reproduction of the problem
Dojo example: https://dojo.telerik.com/UhExAXIv/5
- Click, hold and slowly drag the header of the OrderDate column over the locked ID column.
- Attempt to reorder the OrderDate column before the ID column.
Current behavior
The reorder hint appears only when you hover the left border of the ID cell. This makes dropping the header at the right spot difficult, since you have to be very precise and if you are too fast, you have to re-adjust the mouse cursor position right on top of the left border of the cell.
Expected/desired behavior
The reorder hint should appear when mouse cursor enters the boundaries of the target cell. For example, slowly drag ShipCity before ShipCountry. Note how the reorder hint appears once you enter the boundaries of the ShipCountry cell and you don't have to drag all the way to ShipCountry's left border.

Hello telerik support,
recently we updated to 2023.2.718
somehow the grid column menu is not completely in german language
How can I apply german language to the complete column menu?
Best regards
Andy
Please could you update this example in your GitHub regarding how to export the Kendo UI Grid data on the server as ITextSharp is deprecated?
Thank you!
Add a class to cells in a sorted column (similarly to the .k-sorted class in a sorted column's <th> element) to distinguish them from cells in unsorted columns.
