Bug report

The attributes handler overload does not get executed when the column is initially marked as hidden.

Reproduction of the problem

1. Open the following dojo.
2. Change the hidden property of the ContactTitle field to true.

Current behavior

The attributes handler is not executed when the column is hidden.

Expected/desired behavior

The attributes handler should be executed when the column is hidden.

Environment

• Kendo UI version: 2023.1.425
• Browser: [all]

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

1. In an ASP.NET MVC app install the Telerik.UI.for.AspNet.Mvc NuGet package.
2. The NuGet package adds the kendo theme files to the MyApp\Content\kendo\2024.2.514
3. 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.

### 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]

Is it possible to add the ClientTemplateView() to load a partial view into the column template?

@(Html.Kendo().Grid <OrderViewModel>()
        .Name("grid")
        .Columns(columns =>
        {
            columns.Bound(p => p.ShipName).ClientTemplateView(Html.Partial("~/Views/Details/MyView.cshtml")); 
            ...
        })
        ...
)

Bug report

The Grid cell does not enter edit mode on double tap on iOS in Chrome and Edge. Works correctly in Safari.

Reproduction of the problem

1. Run this dojo example on iOS in Chrome or Edge: https://dojo.telerik.com/idOVAZiP/3
2. Double tap a cell to edit its value

Current behavior

The cell does not enter edit mode.

Expected/desired behavior

The cell enters edit mode.

Environment

• Kendo UI version: 2023.3.1114
• jQuery version: x.y
• Browser: [iOS Chrome, iOS Edge]

### 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]

Bug report

Reproduction of the problem

1. Go to https://demos.telerik.com/aspnet-mvc/grid/paste-from-excel
2. Inspect the Grid toolbar

Current behavior

No dropdown is rendered.

Expected/desired behavior

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>

Environment

• Kendo UI version: 2024.2.514
• jQuery version: x.y
• Browser: [all]

Bug report

The specific here is the disabled Sortable configuration. With Sortable enabled, the rendering on the header content is correct.
Similar issue: #6955

Reproduction of the problem

1. Initialize a Grid without setting Sortable:

@(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"))
    )
)

2. Inspect the rendering of a column header

Current behavior

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.

Expected/desired behavior

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>

Environment

• Kendo UI version: 2024.2.514
• jQuery version: x.y
• Browser: [all]

### 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

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);
    })
    .Sortable()
    .Filterable()
    .Pageable()
    .Scrollable()
    .HtmlAttributes(new { style = "height:430px;" })
    .DataSource(dataSource => dataSource
        .Ajax()
        .PageSize(20)
        .Read(read => read.Action("Orders_Read", "Grid"))
     )
)

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'>
        ...
    </a>
</span>

It should match the Kendo UI Grid's rendering: https://dojo.telerik.com/oTalIGir/8

Environment

• Kendo UI version: 2024.1.130
• jQuery version: x.y
• Browser: [all]

Bug report

Reproduction of the problem

1. 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.

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" });

                  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.

Environment

• Kendo UI version: 2024.1.130
• Browser: [all]

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.

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]

Bug report

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

1. Click, hold and slowly drag the header of the OrderDate column over the locked ID column.
2. 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.
