Bug report

Tooltip produces inconsistent behavior upon hovering when the content is configured through the content client-side configuration.

Reproduction of the problem

1. Navigate to the Loading Content with AJAX or the Content Template demos.
2. Hover over the first element.
3. Hover over the second element and notice that the content is not shown.

Current behavior

For every second hover, the Tooltip does not display the element's content.

Expected/desired behavior

For every second hover, the Tooltip should display the element's content.

Environment

• Kendo UI version: 2023.1.314
• Browser: [all]

I have a model with configured Display and Required DataAnnotation.

However the TagHelper Grid doesn't serialize them because it is lacking a configuration property to bind to a Model like the HtmlHelper does:

@(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.CustomValidationProductViewModel>() 
        .Name("grid")      
        ...
 )

Can this capability be implemented for the TagHelper as well?

Expose the ability to specify an Edit Form Type mode for the Grid similar to the Telerik UI for ASP.NET AJAX control:

### Bug report

When the Grid group paging is enabled, and the Grid is grouped, when the user search through the built-in search panel, and expand a specified group, an infinite loop appears. The Grid sends Read requests, and the server returns empty "data" property.

### Reproduction of the problem

1) Create a Grid bound to remote data and enable the group paging feature.

2) Group the Grid by a specified column.

3) Enter a value in the Grid search panel (the grouped data is filtered).

4) Expand a specified group --> it causes an infinite loop.

5) Open the browser Network tab to review the Read requests.

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

### Expected/desired behavior

The grouped Grid data should be filtered through the search panel as expected.

### Environment

Bug report

Filtering a column bound to a complex object throws a JavaScript error.
This is a regression introduced with v 2023.1.117

Reproduction of the problem

1. Run this REPL or this dojo
2. Click on the filter icon of the Category column

Current behavior

JavaScript error is thrown and the filter menu is not generated.

Expected/desired behavior

Filtering should work as expected.

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]

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
• 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

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

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.

### 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.
