Bug report

When a modal Dialog is open, if we open a modal Window and then attempt to close it, a js exception is thrown. This is a regression introduced in version 2024.1.319.

Reproduction of the problem

Run the following dojo example: https://dojo.telerik.com/IrEWEHAZ

1. Click the "Open Nested Window" button.
2. After the Window opens, try to close it by clicking its "x" button.

Current behavior

A js exception is thrown:
Uncaught TypeError: this._object(...)._overlay is not a function
The issue is related to the modal option being enabled in both the Dialog and the Window. Disabling this option in one of them, prevents the exception.

Expected/desired behavior

The Window closes without exceptions.

Environment

• Kendo UI version: 2024.1.319
• jQuery version: x.y
• Browser: [all]

### Bug report

The legend items cannot be configured in the SeriesDefaults() configuration of the Pie Chart.

### Reproduction of the problem

1) Create a Pie Chart with a visible legend.

2) Add the SeriesDefaults() configuration and try to add the LegendItem() option to set the type of the legend items.

.SeriesDefaults(seriesDefaults =>
{
    seriesDefaults
            .Pie();
            .LegendItem(x => x
                .Type("line")
                .Line(y => y.DashType(ChartDashType.Solid)));
})

The Legenditem() option is available for Telerik UI for ASP.NET Core Pie Chart.

### Expected/desired behavior

The legend items of the Pie Chart must be configurable through the SeriesDefaults() option.

### Environment

* **Telerik UI for ASP.NET MVC version: 2024.1.319
* **Browser: [all]

Bug report

Reproduction of the problem

1. Initialize a PDFViewer and add a button that calls a controller action on click.

<div id="pdfViewer">
</div>

<script type="text/javascript">
    $("#pdfViewer").kendoPDFViewer({
        pdfjsProcessing: {
            file: ""
        }
    });

    function loadFile() {
        $("#pdfViewer").data("kendoPDFViewer").fromFile("@Url.Action("GetPDF", "Home")");
    }
</script>

2. Implement an action that returns a .pdf file or occasionally returns HttpNotFoundResult:

public ActionResult GetPDF()
{

    var name = "sample.pdf";
    string path = Server.MapPath("/Content/pdf/sample.pdf");

    //generate a random boolean:
    Random rng = new Random();
    bool randomBool = rng.Next(0, 2) > 0;
            
    if (randomBool)
    {
        byte[] fileBytes = System.IO.File.ReadAllBytes(path);
        return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, name);
    }
    else
    {
        return new HttpNotFoundResult("File not found.");
    }
}

Current behavior

In the case where the request returns HttpNotFoundResult, a number of js errors are thrown:

util.js:417 Uncaught (in promise)

The user loses the ability to load a file, because subsequent attempts to load a file by clicking the button result in another js exception:

api.js:1114 Uncaught TypeError: Cannot read properties of null (reading 'sendWithStream')

Expected/desired behavior

The component should show a message that a file is not found, without throwing js exceptions and should not become unusable after a failed attempt to load a file.

Bug report

A hidden template column that is not included in the ColumnMenu appears after showing another column

Reproduction of the problem

• Use the following declaration for the columns:

              .Columns(columns =>
              {
                  //Hidden template column
                  columns.Template(x =>
                  {
                      int rptIndex = Model.IndexOf(x);
                      string namePrefix = "Grid[" + rptIndex + "].";
                      Html.Hidden(namePrefix + "Id", x.Id, new { @readonly = "readonly" });
                      Html.Hidden(namePrefix + "Name", x.Name, new { @readonly = "readonly" });
                  }).Hidden().IncludeInMenu(false);

                  columns.Bound(x => x.Id).Width(120).Hidden(true);
                  columns.Bound(x => x.Name).Width(200);
                  columns.Bound(x => x.ReportingDateOriginal).Width(500).HtmlAttributes(new { id = "reporting-date-original" })
                    .Filterable(f => f.UI(GridFilterUIRole.DateTimePicker).Cell(c => c.Template("dateFilter")));
                  columns.Bound(x => x.Test1).Width(200).Hidden(true);
                  columns.Bound(x => x.TimezoneOffset).Width(200).HtmlAttributes(new { id = "reporting-date-offset" });
                  columns.Bound(x => x.Test2).Width(200).Hidden(true);
                  columns.Bound(x => x.ReportingDateAdjusted).Width(500).HtmlAttributes(new { id = "reporting-date-adjusted" })
                    .Filterable(f => f.UI(GridFilterUIRole.DateTimePicker).Cell(c => c.Template("dateFilter")));
                  columns.Bound(x => x.Test3).Width(200);
                  columns.Bound(x => x.Test4).Width(200).Hidden(true);
                  columns.Bound(x => x.Test5).Width(200);
              })

• Show the Id column

Current behavior

The first time instead of the Id, the template column appears.

Expected/desired behavior

The Id column should appear and the template column should remain hidden.

Environment

• Browser: [all]

### Bug report

When server-side localization is used (the culture is different than the default one ("en-US")), all columns are filterable, even when the Filterable() configuration is disabled.

### Reproduction of the problem

1) Create a filterable TreeList and disable the filtering of a specified column.

2) Set the server-side culture to "es-ES".

//Web.config

<system.web>
    <globalization uiCulture="es-ES" culture="es-ES"></globalization>
</system.web>

//View.cshtml
@(Html.Kendo().TreeList<UserViewModel>()
        .Name("treelist")
        .Columns(columns => {
            columns.Add().Field(p => p.id).Filterable(false);
            columns.Add().Field(p => p.Name);
            ...
        })
	.Filterable(true)
	...
)

3) The "id" column is filterable even though the filtering is disabled:

### Expected/desired behavior

The filtering per column must be configurable irrespective of whether localization is used or not.

### Workaround

After the TreeList is initialized, call the setOptions() method and disable the filtering of the respective columns:

<script>
    $(document).ready(function () {
        var treelist = $("#treelist").getKendoTreeList();
        if (treelist) {
            var colOptions = treelist.columns;
            colOptions[0].filterable = false;
            treelist.setOptions({ columns: colOptions });
        }
    })
</script>

Bug report

The rendering (structure and order of elements) of the th element of a column, for which a HeaderTemplate is set, does not match the Kendo UI Grid's rendering in a similar scenario. Prerequisites: HeaderTemplate, Sortable, Filterable enabled. For more context, see Ticket ID: 1639834.

Reproduction of the problem

Check the rendering of the header of the second column:

@(Html.Kendo().Grid<TelerikMvcApp1.Models.OrderViewModel>()
    .Name("grid2")
    .Columns(columns => {
        columns.Bound(p => p.OrderID).Filterable(false).Width(100);
        columns.Bound(p => p.Freight).HeaderTemplate("<span class='k-link'>My Template</span>");
        columns.Bound(p => p.OrderDate).Format("{0:MM/dd/yyyy}").Width(140);
        columns.Bound(p => p.ShipName);
        columns.Bound(p => p.ShipCity).Width(150);
    })
    .Sortable()
    .Filterable()
    .Pageable()
    .Scrollable()
    .HtmlAttributes(new { style = "height:430px;" })
    .DataSource(dataSource => dataSource
        .Ajax()
        .PageSize(20)
        .Read(read => read.Action("Orders_Read", "Grid"))
     )
)

Current behavior

The content of the th is the following:

<a aria-hidden="true" class="k-grid-filter-menu k-grid-header-menu">
    ...
</a>
<span class="k-link">
    ...
</span>

Expected/desired behavior

The th content should be rendered as follows:

<span class='k-cell-inner'>
    <span class='k-link'>
        ...
    </span>
    <a aria-hidden='true' class='k-grid-filter-menu k-grid-header-menu'>
        ...
    </a>
</span>

It should match the Kendo UI Grid's rendering: https://dojo.telerik.com/oTalIGir/8

Bug report

The DropDownList is incorrectly marked as invalid, when another field of the model is invalid.

Reproduction of the problem

Sample project attached.
MVCFormValidation.zip

1. Run the project
2. Click the submit button. It submits the form and in the submit action a model error is added to a specific field of the model: ModelState.AddModelError("NumberOfShares", "Number not in the expected range");

Current behavior

Two validation errors appear after the form submission: one for the NumberOfShares field and a second one for the Country.Id field, for which a DropDownList editor is used.

Expected/desired behavior

A validation error appears only for the NumberOfShares field.
Note that if no editor is specified for the Country.Id field (instead of using a DropDownList editor), e.g.,

	i.Add()
	    .Field(f => f.Country.Id)
	    .Label(l => l.Text("Country"));

no validation error message is shown for Country.Id.

Bug report

If a RadioGroup is used for editing a required field, the validator is fired if a selection is not made. However, when selecting a field after the validation message appears and blurring the field, the other inputs of the RadioGroup remain marked as invalid.

Reproduction of the problem

Open the dojo:
https://dojo.telerik.com/eSEliROr/3

1. Try to submit the form.
2. The validation is triggered since the form is invalid, which is correct.
3. Select Name and click anywhere on the page.
4. The other options are still recolored as invalid

Expected/desired behavior

When an option is selected and the input is no longer focused, the validation message should disappear. Also, the other inputs should no longer be marked as invalid.

Bug report

Reproduction of the problem

Dojo example: https://dojo.telerik.com/InUYAheR/4
Drag and drop a row from Grid2 to Grid1 by following the steps below:

1. Click and hold down the mouse button within a Grid2 row, just before its ID value or a little after it.
2. Drag the row to Grid1 and drop it over row 3 or row 4.

Current behavior

Grid1's first row values get updated, instead of the drop target row values. This is because e.target in the DropTarget's "drop" event does not return the actual target you drop over.
If you click and drag in the middle of the Grid2 row, drag it and drop it over a row in Grid1, the drag and drop functionality works as expected: e.target returns the correct target.

Expected/desired behavior

e.target should consistently return the target you drop over, regardless of where in the dragged row you have clicked.
