Is it possible to implement an option for the Telerik UI for ASP.NET Core Grid to change the default filter operator "eq" to "contains" when the Grid column checkbox filter menu is enabled?

For example:

columns.Bound(p => p.ShipName)
  .Filterable(ftb => ftb
    .Multi(true)
    .Search(true)
    .Operators(op => op
      .ForString(s => s
        .Clear()
        .Contains("Contains")
)));

//Filter expression:
filter: ShipName~contains~'test'

Hello Team Telerik,

we have a Grid with a Select column:

...
.Columns(c =>
        {          
                c.Select().Width(50)
....

We want to give users the ability to quickly group rows that are selected. However, grouping the Grid by the Select() column is not possible

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"))

### 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]

### 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.

### Environment

* **Kendo UI version: 2022.2.802
* **jQuery version: 1.12.4
* **Browser: [all]

Bug report

Grid's headers break upon ungrouping when the filterable mode is set to "row"

Reproduction of the problem

1. Run the following dojo.
2. Drag a column for grouping.
3. Ungroup the column.

Current behavior

Upon ungrouping the Grid's headers are disrupted.

Expected/desired behavior

The Grid's headers should not be disrupted upon ungrouping.

Environment

• Kendo UI version: 2022.3.913
• Browser: [all]

Bug report

When the Grid's PopUp Editing is enabled on mobile devices there are additional inputs or missing styling in the PopUp.

Reproduction of the problem

1. Open the Grid's Adaptive Rendering Demo
2. Scan it with your mobile device and open the Demo on it
3. Click the 'Add new record' or 'Edit'

Note: The issue doesn't reproduce in a browser's DevTools on desktop

Current behavior

The PopUp is misaligned or its styles are missing on mobile devices

Environment

• Browser: [ Mobile Chrome | Android Web Browser | iOS Safari ]

### 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.

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 ]

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
