I'm in the process of rewriting all Kendo components to use CSP compatible templates. I'm looking at https://docs.telerik.com/aspnet-core/html-helpers/template/overview which shows how we'd use TemplateComponentName() for popup editors and that we would need to rewrite everything in the popup editor to use Kendo Template's AddHtml or AddComponent methods.

Original:

<div class="mb-2 row required">
	@Html.LabelFor(model => model.FileName, new { @class = "col-sm-4 col-form-label fw-bold text-sm-end" })
	<div class="col-sm-6">
		@(Html.Kendo().TextBoxFor(model => model.FileName).HtmlAttributes(new { @class = "w-100" }))
	</div>
</div>

<div class="mb-2 row">
	@Html.LabelFor(model => model.FileDescription, new { @class = "col-sm-4 col-form-label fw-bold text-sm-end" })
	<div class="col-sm-6">
		@(Html.Kendo().TextBoxFor(model => model.FileDescription).HtmlAttributes(new { @class = "w-100" }))
	</div>
</div>

Rewritten:

@(Html.Kendo().Template()
	.AddHtml("<div class='mb-2 row required'>")
	.AddHtml(@<text>
		@Html.LabelFor(model => model.FileName, new { @class = "col-sm-4 col-form-label fw-bold text-sm-end" })
	</text>)
	.AddHtml("<div class='col-sm-6'>")
	.AddComponent(c => c.TextBoxFor(model => model.FileName).HtmlAttributes(new { @class = "w-100" }))
	.AddHtml("</div></div>")

	.AddHtml("<div class='mb-2 row'>")
	.AddHtml(@<text>
		@Html.LabelFor(model => model.FileDescription, new { @class = "col-sm-4 col-form-label fw-bold text-sm-end" })
	</text>)
	.AddHtml("<div class='col-sm-6'>")
	.AddComponent(c => c.TextBoxFor(model => model.FileDescription).HtmlAttributes(new { @class = "w-100" }))
	.AddHtml("</div></div>")
)

While this works, this markup seems much harder to read than the original. Could this be made to be simpler? Ideally I'd like to be able to drop my existing mix of html and kendo components in one method and it'd parse through to render the template properly.

### Bug report

When an Editor component in inline mode is set as an editor in an InCell editable Grid, the Grid cell does not enter edit mode on "click". The issue occurs since version 2023.1.314.

### Reproduction of the problem

1) Create an InCell editable Grid.

2) Set an Editor component in inline mode as an editor to a specified Grid column.

3) Try to edit the cell.

4) The cell flashes and does not enter edit mode.

A Dojo sample for reporduction: https://dojo.telerik.com/zQUvDQEq (check out the "ProductName" column)

### Expected/desired behavior

The Grid column that uses Editor component in inline mode must be editable.

### Environment

* **Kendo UI version: since 2023.1.314
* **jQuery version: 3.4.1
* **Browser: [all]

As a result of an EF Core issue, the ToDataSourceResult() is not able to perform the query when the DataSourceRequest object contains grouping.

The problem occurs using the query below, assembled by Telerik routine:

var temp = _db.Pessoa
    .OrderBy(item => item.Email)
    .Skip(0)
    .Take(40)
    .GroupBy(item => item.Email)
    .OrderBy(g => g.Key)
    .Select(g => new AggregateFunctionsGroup
    {
        Key = g.Key,
        ItemCount = g.Count(),
        HasSubgroups = false,
        Member = "Email",
        AggregateFunctionsProjection = new
        {
            Count_Referencia = _db.Pessoa
                    .Select(t => new
                    {
                        t.IdPessoa,
                        t.Referencia,
                        t.Nome_RazaoSocial,
                        t.Apelido_Fantasia,
                        t.CPF_CNPJ,
                        t.RG_IE,
                        t.Email
                    })
                    .OrderBy(item => item.Email)
                    .Where(item => item.Email == g.Key)
                    .Count()
        },
        Items = g
    })
    .ToList();

In the routine where the AggregateFunctionsGroup is created, the Items property must not only be the query itself, but also the fields specified in the main Select. Or, the call to the Select() method must simply be added:

var temp = _db.Pessoa
    .OrderBy(item => item.Email)
    .Skip(0)
    .Take(40)
    .GroupBy(item => item.Email)
    .OrderBy(g => g.Key)
    .Select(g => new AggregateFunctionsGroup
    {
        Key = g.Key,
        ItemCount = g.Count(),
        HasSubgroups = false,
        Member = "Email",
        AggregateFunctionsProjection = new
        {
            Count_Referencia = _db.Pessoa
                    .Select(t => new
                    {
                        t.IdPessoa,
                        ...
                    })
                    .OrderBy(item => item.Email)
                    .Where(item => item.Email == g.Key)
                    .Count()
        },
        Items = g.Select(t => new
        {
            t.IdPessoa,
            ...
        })
    })
    .ToList();

This way, the issue does not occur.

Bug report

Reproduction of the problem

Dojo example: https://dojo.telerik.com/eRazIrIB

1. Scroll the Grid

Current behavior

The data is requested, but it is not displayed in the Grid.

Expected/desired behavior

The data is displayed, regardless of the type of loader used.

Environment

• Kendo UI version: 2022.3.913
• jQuery version: x.y
• Browser: [all ]

The grid must allow changes to be made in specific cells, without those changes being committed/saved unless the user clicks on the "Save" button in the toolbar. Basically the users enter in some values for editable currency columns that aren't locked, and (without saving) some columns (both locked and not locked) that are not editable must be refreshed as the value in those cells depend on the edited column. Those cells have client templates and client footer templates which need to be used by whatever is refreshing their cells.

Having this functionality provided built-in will be a nice addition:

### Bug report

When opening the filter menu of a specified column through the classic ColumnMenu, the filter container is displayed with scrollbars when the dropdown of the filter operator is opened.

### Reproduction of the problem

1) Define a Grid and enable its classic ColumnMenu.

2) Open the filter menu of a specified column and then open the dropdown to select a filter operator.

3) The filter container has scrollbars. The "k-menu-popup" element has "overflow: auto";

Use the following demo to test the case and select the "classic" type for the ColumnMenu: https://demos.telerik.com/kendo-ui/grid/column-menu

The issue does not appear when using version 2024.4.1112.

### Expected/desired behavior

The filter menu container must not change its appearance when the dropdown opens.

### Workaround:

<style>
.k-menu-popup {
    overflow: visible !important;
}
</style>

Bug report

The column format applied through the .Format() option is ignored, if the column is bound to a nullable DateOnly field.

Reproduction of the problem

1. Declare a nullable DateOnly field in the view model:

public DateOnly? PaymentDate { get; set; }

2. Bind a column to the field and set its format:

columns.Bound(p => p.PaymentDate).Title("Date").Format("{0:MM/dd/yyyy}").Width(160);

Current behavior

The specified format is ignored, e.g., the Grid shows 2025-01-21, instead of 01/21/2025

Expected/desired behavior

The specified column format is applied.

Environment

• Kendo UI version: 2024.4.1112
• Browser: [all ]

### Bug report

When the Grid filter menu is customized with a DropDownList, the initial option defined by using the "index" property is not set.

### Reproduction of the problem

A Dojo sample for reproduction: https://dojo.telerik.com/OmeXUfaF

### Expected/desired behavior

The DropDownList should be initialized with an initially selected option.

### Environment

* **Kendo UI version: 2022.1.119
* **jQuery version: 1.12.4
* **Browser: [all]

Bug report

Reproduction of the problem

1. Open the following dojo.
2. Open the column menu.
3. Try to remove all columns through the checkboxes.

Current behavior

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:

Expected/desired behavior

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.

Environment

• Kendo UI version: 2023.3.1010
• jQuery version: x.y
• Browser: [all]

Trouble on iPad 6/7/8 with Safari.

Using grid with batch and incell edit mode.

Datepicker is not working. It just shows the text box to manually type in date.

Every once in a while the date picker pops up and stays for selection.

Sometimes I see the dat picker, but it goes away suddenly before being able to set a date.

Current configuration: server-side filtering

Desired behavior:

1. Grid searches are "anded" to any existing filters
2.  When the search box is cleared the pre-existing filters are retained

Bug report

When ParseFormats is set in the DatePicker editor used in the Grid popup, the picker does not show the field value to which it is bound.

Reproduction of the problem

1. Add a DateOnly? field to the model:

public DateOnly? OrderDate { get; set; }

2. Bind a Grid column to the field.
3. Set the default value in the DataSource:

.Model(model =>
{
    model.Id(p => p.OrderID);
    model.Field(p => p.OrderDate).DefaultValue(new DateOnly());
})

4. Configure Popup editing in the Grid.
5. Add a DateOnly.cshtml editor in EditorTemplates:

@model DateOnly?

@(Html.Kendo().DatePickerFor(m => m).ParseFormats(new string[] { "MM/dd/yyyy" }).HtmlAttributes(new { title = Html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName("") }))

Current behavior

When editing a record. The value of the OrderDate field is not displayed in the DatePicker.
If you remove the ParseFormats option from the DatePicker, it shows the value as expected.

Expected/desired behavior

The field value should be displayed in the picker, even when ParseFormats is set.

Environment

• Kendo UI version: 2024.4.1112
• Browser: All

Bug report

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.

Reproduction of the problem

1. Run this Telerik REPL or this Dojo
2. Reorder a row
3. Open the browser's Network Tab
4. Click the Save Changes button

Expected/desired behavior

The Grid should request the reordered item to be perished from the backend.

Environment

• Kendo UI version: 2023.2.718

### Bug report

When the Grid is initialized in a hidden container (for example, in a non-selected tab of a TabStrip) and its initial data binding is disabled (autoBind: false), the pager information is not visible when the data is loaded afterward.

### Reproduction of the problem

1. Initialize a Grid into a non-selected tab of a TabStrip and set its autoBind option to "false".

2. Select the tab and check how the empty Grid is rendered.

3. Call the read() method of the Grid's DataSource in the browser console to request the data.

4. The data is loaded, but the pager information remains hidden.

A Dojo sample for reproduction: https://dojo.telerik.com/njVgBvza

### Expected/desired behavior

The pager information must be available when the data is loaded into the Grid.

### Environment

* **Kendo UI version: 2024.4.1112
* **jQuery version: 3.7.1
* **Browser: [all]

Bug report

Dynamic Grid produces a RunTimeException when the Filterable() configuration is enabled

Reproduction of the problem

1. Configure the dynamic Grid based on the following example.
2. Set the .Filterable() API configuration of the Grid.
3. Notice that the application throws a System.ArgumentNullException: Value cannot be null.

Example

@model System.Data.DataTable

@(Html.Kendo().Grid<dynamic>()
    .Name("gridItem")
    .Columns(columns =>
    {
        foreach (System.Data.DataColumn dcolumn in Model.Columns)
        {
            columns.Bound(dcolumn.ColumnName).Title(dcolumn.Caption);
        }
    })
     ...
    .Filterable()
)

The aforementioned declaration will work in the previous 2024.3.1015 version of the suite.

Current behavior

The Grid makes the application throw a runtime error.

Expected/desired behavior

The Grid makes the application should not throw a runtime error.
