The specific here is the disabled Sortable configuration. With Sortable enabled, the rendering on the header content is correct.

The column name is nested directly in the th element, instead of being wrapped in additional elements like in the Kendo UI for jQuery Grid or in the Grid for ASP.NET Core.
The column name should be wrapped in additional span elements with classes k-cell-inner, k-link, k-column-title:
<span class="k-cell-inner">
<span class="k-link">
<span class="k-column-title">Ship Name</span>

### 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:
<span class="k-cell-inner"><span class="k-link"><span class="k-column-title">Product Information</span></span></span>
### Environment
* **Telerik UI for ASP.NET MVC version 2024.2.514
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
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;
}
The theme files distributed through CDN and NuGet should be identical.
Reproducible in MVC with a custom toolbar tool that has a ClientTemplate.
@(Html.Kendo().Grid<TelerikMvcApp2.Models.OrderViewModel>()
.Name("grid")
.Columns(columns =>
{
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);
})
.ToolBar(toolbar =>
{
toolbar.Save();
toolbar.Spacer();
toolbar.Custom().ClientTemplate("<span>test</span>");
})
.Pageable()
.Sortable()
.Scrollable()
.Filterable()
.HtmlAttributes(new { style = "height:550px;" })
.Editable(editable => editable.Mode(GridEditMode.InCell))
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Model(model => model.Id(p => p.OrderID))
.Read(read => read.Action("Orders_Read", "Grid"))
.Create("Orders_Create", "Grid")
.Update("Orders_Update", "Grid")
)
)
Duplication of the "Cancel" button.
A single "Cancel" button is rendered in the toolbar.
### 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
* **Telerik UI for ASP.NET Core/MVC: 2024.1.319
* **Browser: [all]
A hidden template column that is not included in the ColumnMenu appears after showing another column
.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);
})
The first time instead of the Id, the template column appears.
The Id column should appear and the template column should remain hidden.
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.
Reproducible with a Grid nested in the content of the tab, or loaded in the tab through AJAX.

The rows cannot be reordered.
The rows can be reordered.
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.
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);
})

.HtmlAttributes(new { style = "height:430px;" })
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Read(read => read.Action("Orders_Read", "Grid"))
)
)
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>
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'>
...
</a>
</span>
It should match the Kendo UI Grid's rendering: https://dojo.telerik.com/oTalIGir/8
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.
Dojo example: https://dojo.telerik.com/UhExAXIv/5
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.
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.

In addition to the Foreign Key editor template, populate a list which holds all the categories and pass it via the ViewData - you can see how this is done in the ForeignKeyColumnController.cs PopulateCategories()
method.
On the above page, the above statement is made. Other than the function call to PopulateCategories() I don't ever see the actual code run in the function shown anywhere. Can someone please add that code and/or point me to my misunderstanding?
Thank you.

The issue is present only when a field in the model has been updated. When an invalid value is attempted to be saved, the validation is triggered. Upon pressing the Esc key, the dirty indicator should not be shown.
The expected behavior would be to not show the dirty indicator at all as the value has been returned to the initial one. Furthermore, the indicator is not positioned in the left top corner but immediately above the value.
Steps to replicate:
1. Change the value of any field.
2. Navigate to a field which has validation.
3. Set an invalid value in order to trigger the validation, respectively show a validation message.
4. Press Esc to undo the change.
5. The dirty indicator is shown and mispositioned.

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.
<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)

)
)
<script>
function btn1Click() {
var grid = $("#Grid").data("kendoGrid");
grid.showColumn("ShipCity");
grid.showColumn("OrderDate");
}
</script>
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");
The columns and their headers are shown.
