Bug report

The TagHelper Grid's TagHelper is not correctly serialized and cannot be used to export hidden columns.

Reproduction of the problem

• Set the exportable TagHelper for a hidden column to enabled.

<columns>
    <column field="Discontinued" hidden="true">
         <exportable enabled="true" />
    </column>
</columns>			  

• Open the following REPL example.
• Export the Grid and observe the exported document.

Current behavior

The Grid TagHelper does not export hidden columns if the exportable TagHelper is enabled identically to the Kendo UI for jQuery Grid column exportable option.

Expected/desired behavior

The Grid TagHelper should be able to export hidden columns if the exportable TagHelper is enabled identically to the Kendo UI for jQuery Grid column exportable option.

Environment

• Kendo UI version: 2022.3.1109
• Browser: [all]

I have a grid where the editor button should not be with text so I added a class to the button like this:

@(Html.Kendo().Grid<...>()
      .Name("...")
      .Columns(columns =>
      {
         columns.Command(command => command.Edit()
                                           .Text(" ")
                                           .HtmlAttributes(new { @class = "grid-button-notext", title = "..." }));
      })
      .Editable(editable => editable.Mode(GridEditMode.PopUp)
                                    .TemplateName("..."))
)

but the HtmlAttributes are applied also to the two buttons on the popup editor

<div class="k-edit-buttons k-actions-end">
   <button type="button" class="k-grid-update grid-button-notext k-button k-button-md k-rounded-md k-button-solid k-button-solid-primary" title="...">
     <span class="k-icon k-i-check k-button-icon"></span>
     <span class="k-button-text">Save</span>
   </button>
   <button type="button" class="k-grid-cancel grid-button-notext k-button k-button-md k-rounded-md k-button-solid k-button-solid-base" title="...">
      <span class="k-icon k-i-cancel k-button-icon"></span>
      <span class="k-button-text">Cancel</span>
   </button>
</div>

Expected behaviour:

the HtmlAttributes to be applied only to the grid button. And if needed to provide PopupButtonHtmlAttributes like you have for column: HtmlAttributes, HeaderAttributes, FooterAttributes

Bug report

Reproduction of the problem

• Run the following Telerik REPL.
• Notice the logged error within the console.

Current behavior

Having a grid with a similar column setup will result in an error.

.Columns(columns =>
{
    columns.Bound(p => p.UnitsInStock).HtmlAttributes(new { @class = "#: UnitsInStock == 39 ? 'test' : 'a' #" });
})

Expected/desired behavior

Having a grid with a similar column setup should not result in an error.

.Columns(columns =>
{
    columns.Bound(p => p.UnitsInStock).HtmlAttributes(new { @class = "#: UnitsInStock == 39 ? 'test' : 'a' #" });
})

Environment

• Kendo UI version: 2022.3.913

### Bug report

When the Grid Column Menu is set to "modern", the ButtonGroup "And"/"Or" in the Filter menu is not translated.

### Reproduction of the problem

1. Create a Grid and enable the ColumMenu with the type "modern".

2. Include the localization script "kendo.messages.de-CH.min.js" and the culture file "kendo.culture.de-CH.min.js".

3. Set the Kendo culture to "de-CH".

4. Open the ColumnMenu of a specified Grid column and then the Filter menu. The messages "And/Or" are not translated. The messages are translated as expected when using the default ColumnMenu.

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

### Expected/desired behavior

The Filter menu ButtonGroup should be translated when using the "modern" ColumnMenu.

### Environment

* **Kendo UI version: 2022.3.913
* **jQuery version: 1.12.4
* **Browser: [all]

Bug report

The DataSource's property groupPaging: true prevents the Grid's group from expanding if it has a defined groupHeaderColumnTemplate.

Reproduction of the problem

1. Open this Dojo
2. Try to expand the Grid's groups

Also reproducible in the Core wrapper where an error is thrown: kendo.all.js:8743 Uncaught TypeError: Cannot read property 'hasSubgroups' of undefined

Current behavior

groupPaging is not compatible with the groupHeaderColumnTemplate

Expected/desired behavior

groupPaging and the groupHeaderColumnTemplate should be compatible

Environment

• Kendo UI version: 2021.2.616

• Browser: [all]

Bug report

New lines are not removed from the serialized Toolbar.ClientTemplate when multiline content is provided and the Grid is in a DetailTemplate, thus generating an invalid template and causing a Chrome Exception.

Reproduction of the problem

The following template configuration is valid and works for the parent grid, but not for child grids:

.ToolBar(toolbar => toolbar.ClientTemplate(@" 
            <div class='filter'>
                <span class='k-textbox k-display-flex auto-filter''>
                    <input id='search' autocomplete='off' class='k-input' placeholder='Search...' title='Search...' type='text'>
                    <span class='k-input-icon'><span class='k-icon k-i-search'></span></span>
                </span>
            </div>
        "))

REPL example

Current behavior

Invalid template is generated

Expected/desired behavior

A valid template should be generated

Environment

• Kendo UI version: 2022.2.621
• Browser: [all ]

Expose configuration options for setting the options - Size, ThemeColor, FillMode and Rounded - of the Grid's command buttons and toolbar buttons, as possible for a simple Button component.

Adding a separate configuration for the Cancel command button would also be beneficial. For example:

    .Columns(columns => {   
        columns.Bound(p => p.ProductName);
        columns.Bound(p => p.UnitPrice).Width(140);
        columns.Bound(p => p.UnitsInStock).Width(140);
        columns.Bound(p => p.Discontinued).Width(100);
        columns.Command(command => command.Destroy().ThemeColor(ThemeColor.Error)).Width(150);
    })
    .ToolBar(toolbar => {
        toolbar.Create().ThemeColor(ThemeColor.Info).Size(ComponentSize.Large);
        toolbar.Save().ThemeColor(ThemeColor.Success);
        toolbar.Cancel().ThemeColor(ThemeColor.Warning);
    })

### Bug report

When the Grid is grouped by a specified column, and this column has a "groupFooterTemplate" that contains aggregates from other fields, it cannot be exported to Excel. It throws a JavaScript exception.

### Reproduction of the problem

1) Group the Grid by the column "ProductName".

2) Export it to Excel through the built-in command "Export to Excel".

3) JS exception is thrown.

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

### Expected/desired behavior

The Excel export should work as expected when the Grid is grouped.

* **jQuery version: 1.12.4
* **Browser: [all]

### Bug report

When a non-sortable Grid column header is hovered, the mouse cursor indicates that it is sortable.

### Reproduction of the problem

1. Create a sortable Grid with a non-sortable column.

2. Hover the column header.

3. Mouse cursor is a "pointer".

Here is a dojo sample for reproduction: Untitled | Kendo UI Dojo (telerik.com)

### Expected/desired behavior

Only the headers of the sortable Grid columns should be indicated with a "pointer" when hovered.

### Environment

Kendo UI version: 2022.6.621
jQuery version: 1.12.4
Browser: [all] 

### Bug report

The localization messages for some of the default Grid commands are missing. They are translated in the kendo.messages.he-IL.min.js:

https://github.com/telerik/kendo-ui-core/blob/master/src/messages/kendo.messages.he-IL.js#L302

### Reproduction of the problem

1) Create a Telerik UI Grid and enable the commands Edit(), Destory(), and Create().

2) Set the client-side culture to "he-IL" and register the localization script for that culture.

3) The commands are not translated.

Here is a Dojo sample, where all available localization messages for culture "he-IL" are in place:

https://dojo.telerik.com/UvaMivaS

### Expected/desired behavior

The localization messages from the "kendo.messages.he-IL.min.js" file should be available for the Telerik UI Grid.

### Environment

* **Kendo UI version: 2022.2.621
* **jQuery version: 1.12.4
* **Browser: [all]

Is it possible to implement a method in the Read() configuration of the DataSource that will append parameters as name-value pairs to the query string?

For example:

.Read(r => r.URL(myUrlPath).Handler(myPageHandler).AddQryStrPairs(myNameValuePairsModel))

Currently, I am appending the parameters manually as follows:

.Read(r => r.Url(qurc.PageUrlPath 
 "?handler=Read&area=" +  TkgrArea + "&serviceType=" + qurc.ServiceType.ToString() + "&serviceTag=" + qurc.ServiceTag  + "&entityType=" + qurc.EntityType).Data("forgeryToken"))
