### 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]
@(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"))
)
The filter menu messages are not set.
The filter menu messages are set regardless of whether a ColumnMenu is enabled or not.
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.
### 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
The specific here is the disabled Sortable configuration. With Sortable enabled, the rendering on the header content is correct.
Similar issue: #6955
@(Html.Kendo().Grid<TelerikMvcApp1.Models.OrderViewModel>()
.Name("grid")
.Columns(columns =>
{
columns.Bound(p => p.OrderID).Filterable(false).Width(200);
columns.Bound(p => p.Freight).Width(200);
columns.Bound(p => p.OrderDate).Format("{0:MM/dd/yyyy}").Width(200);
columns.Bound(p => p.ShipName).Width(200);
columns.Bound(p => p.ShipCity).Width(200);
})
.Pageable()
.Scrollable()
.Filterable()
.HtmlAttributes(new { style = "height:550px;" })
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Read(read => read.Action("Orders_Read", "Grid"))
)
)
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>
</span>
... anchor element...
</span>
No dropdown is rendered.
A dropdown is rendered (see the same demo in Kendo UI for jQuery, or UI for ASP.NET Core)
Workaround - call the Grid's setOptions method on document.ready as shown below:
<script>
$(document).ready(function() {
//replace 'grid' with the actual Name value of your Grid:
$("#grid").data("kendoGrid").setOptions({
toolbar: ["paste"]
})
})
</script>
### Bug report
When the Grid is set up for InCell editing, and the column editor is the Upload widget, the user cannot select a file to upload when the Grid is navigatable.
The issue occurs in version >= 2024.1.130
### Reproduction of the problem
1. Create an InCell editable Grid and enable its "navigatable" option.
2. Set the Upload widget as a column editor.
3. Enter a specified cell in edit mode and try to select a file for upload.
4. The cell closes immediately.
A Dojo sample for reproduction: https://dojo.telerik.com/oDaNaLiQ
### Expected/desired behavior
The cell must remain focused when the Upload button is clicked.
### Workaround
Handle the "edit" event of the Grid, handle the "mousedown" event of the Upload button, and call stopImmediatePropagation():
$("#grid").kendoGrid({
editable: true,
navigatable: true,
edit: function(e) {
if($(e.container).find("input[type='file']")) {
$(".k-upload-button").on("mousedown", function (event) {
event.stopImmediatePropagation();
});
}
}
...
});
### Environment
* **Kendo UI version: 2024.1.130
* **jQuery version: 3.7.0
* **Browser: [all]
In a state persistence scenario, the Grid state is not properly restored when the "all" pageSizes option is selected.
The Grid shows page 1 of the data and the currently selected page sizes option is shown (e.g., 20).
The Grid shows all the data and the pager dropdown shows "all" as the selected value.
### Bug report
When the Input() option of the Grid's pager is enabled, the page number buttons are displayed, too.
### Reproduction of the problem
1) Create a Grid and enable the Input() option of the pager.
2) The pager displays both the page number buttons and the page numeric input:
### Expected/desired behavior
When the numeric input is enabled, the page number buttons must not be displayed.
