Implement Recurrence Rule Parser helper that uses the Scheduler recurrenceRule string and parses it in a usable format on the server.

There is already a similar helper for Telerik UI for ASP.NET Ajax.

Hello,

When you add any kind of filter to the grid, he is wrapped inside span with class "k-filtercell". It would be very usefull to add HtmlAttributes to the html element. Last time i wanted to add class only on the filtercell so i can customize the ui to match our theme. The idea was to have expression for each filter type so i can create css only for the filters. Most of the expressions were ok, because they were wrapped inside Template. But in cases like enum i dont want template, i want only to add class to the filtercell, so i can change it. Its not ok for one types to do the changes with filter expression, for other types to make changes with column.HtmlAttributes(...).

If not HtmlAttributes, at least .Class(...).

Regards,

Dinko

Per the documentation for the Grid's Search Panel:

"When the server operations are enabled, you can search only by using string fields."

This is an oddly-specific limitation to have that causes an awkward user experience. Grids in some areas with limited data might use client operations and, as a result, the Search Panel is capable of searching all columns in a Grid. Other areas, however, might have grids with significantly more data and be using server operations for performance reasons. A side-effect of this would mean the Search Panel is incapable of filtering on non-string fields. This not only might lead to unexpected results to an end-user, but also requires the developer to explicitly list each string field that can be searched. If a developer forgets to list only string fields, the default action will be for it to attempt to filter on all fields. If any fields happen to not be strings, you still get a loading indicator as if it's attempting to filter, but the Ajax request silently fails and returns an error 500 behind the scenes.

There are some manual workarounds discussed here, as well as some information as to why this limitation exists. It seems like the problems causing these limitations are known, as are some rough workarounds to get around it. It would be great if we could get some official support to address this limitation so developers aren't left to either work around it on their own or avoid using this feature altogether. This feature would be great if it weren't for this limitation. A single place to quickly and easily type in something to filter on, and have that filter applied against all columns could definitely save some time and be very useful, but with this limitation with a pretty technical explanation (from an end-user perspective), the unexpected mixed results could instead lead to confusion and frustration, and distrust of this feature.

### Bug report

The Button TagHelper is missing in the Visual Studio 2022 IntelliSense.

Bug report

Setting the HeaderHtmlAttributes of the TreeList throws a Null reference exception.

Reproduction of the problem

1. In the Multi-column headers Demo of the Treelist try adding HeaderHtmlAttributes to a Group:

@(Html.Kendo().TreeList<Kendo.Mvc.Examples.Models.TreeList.EmployeeDirectoryModel>()
        .Name("treelist")
        .Columns(columns =>
        {
            columns.Group(group => group
                .Title("Personal Info")
                .HeaderHtmlAttributes(new {@class="myClass"})
                .Columns(info =>
                {
                  //...
                })
            );
        })

Current behavior

Null reference exception is thrown.

Expected/desired behavior

The Html attributes should be added to the header.

Bug report

When importing a xlsx file containing custom data validation and the "@" symbol a JavaScript error is thrown.

Reproduction of the problem

Import the this sample file that contains the custom validation formula =ISNUMBER(MATCH("*@*",A1,0)) in the Server Import/Export Demo. The following error is thrown and logged on the developer's console:
Can't handle character with code: 64 (input: \"ISNUMBER(MATCH(\"*@*\",A1,0))\")"

Opening the file with the built-in open command works as expected as well as hardcoding the formula - REPL

Expected/desired behavior

Importing a xlsx file containing custom data validation and the "@" symbol should not throw a JavaScript error.

### Bug report

The MultiSelect TagHelper is rendered as a DropDownList and does not allow multiple selections.

### Reproduction of the problem

### Bug report

The Column.Exportable option is not correctly serialized and cannot be used to export hidden columns.

### Reproduction of the problem

1. Set Column.Exportable(true) and Column.Hidden(true).

2. Export the grid and see that the column is not present in the exported file.

### Bug report

When the filter is applied through the search panel, the query (more specifically, the filter expressions) is not built correctly. This results in displayed rows that have values that do not match the value from the search panel.

### Reproduction of the problem

1. Enable Search panel and group paging of the grid.

2. Set a value in the search panel and group by a column.

3. Expand the group and verify that there are items with values that do not match the filter expression from the search panel.

Short video demonstration:

https://screencast-o-matic.com/watch/crXFlXVI3i0

### Expected/desired behavior

The returned results should comply with the filter expression built from the Search panel.

### TicketID:
_1543306

### Additional notes and explanation

The Search panel builds the filter expression with the logic operator "or". While this is correct when the actual query is further built from the data source's internals (group function of the kendo.data.js file), the filter will be built with the "or" logic instead of "and". This query has to be restructured in order to send two filter objects with the "and" logic. The first filter object should contain all filter expressions built from the search panel with the "or" logic operator and the second filter object should contain an expression with the operator "eq", the field by which the group is built, and the value. The two filter objects should be combined with the "and" logic.

If I manually enter the date in the cell the model binder parses the date as it was not an UTC and since my time zone is +2h it comes in the controller as 25.12.2021 22:00

(see the attached files)

Inside my startup.cs I have defined JsonOptions like this:

.AddNewtonsoftJson(options =>
                {
                    options.SerializerSettings.ContractResolver = new DefaultContractResolver();
                    options.SerializerSettings.DateTimeZoneHandling = DateTimeZoneHandling.Utc;
                });

In the Configure method:

var supportedCultures = new[] { new CultureInfo("bg-BG") };

app.UseRequestLocalization(new RequestLocalizationOptions
{
         DefaultRequestCulture = new RequestCulture("bg-BG"),
         SupportedCultures = supportedCultures,
         SupportedUICultures = supportedCultures
});

Bug report

When using the TaxtBoxFor HTML helper and the MaxLength is set via DataAnnotation the maxlength attribute is not rendered.

Reproduction of the problem

Model:

public class MyModel
{
    [MaxLength(5)]
    public string Text { get; set; }
}

View:

@Html.Kendo().TextBoxFor(m => m.Text)

Current behavior

The Telerik UI for ASP.NET Core HTML Helper renders the following markup, without the maxlength attribute:

<span class="k-widget k-textbox" style="">
    <input data-val="true" data-val-maxlength="The field Text must be a string or array type with a maximum length of '5'." data-val-maxlength-max="5" id="Text" name="Text" value="" data-role="textbox" aria-disabled="false" class="k-input" autocomplete="off" style="width: 100%;">
</span>

The default Html.TextBoxFor helper renders the following markup, containing the maxlength attribute:

<input data-val="true" data-val-maxlength="The field Text must be a string or array type with a maximum length of '5'." data-val-maxlength-max="5" id="Text" maxlength="5" name="Text" type="text" value="">

Expected/desired behavior

The Telerik UI for ASP.NET Core HTML Helper should render the maxlength attribute.
