Bug report

Using the PDFViewer with the latest version of PDF.js (3.9.179) throws js exceptions. Version 3.4.120 is the last one, with which no js exception is thrown.

Reproduction of the problem

Dojo example: https://dojo.telerik.com/IHedIhur/3

1. Open the devtools consolve and run the example.

Current behavior

The file is loaded, however, js exceptions are thrown:

The --scale-factor CSS-variable must be set, to the same value as viewport.scale, either on the container-element itself or higher up in the DOM. text_layer.js:480:14

Expected/desired behavior

No js exceptions when using PDF.js versions newer than v3.4.120.

Environment

• Kendo UI version: 2023.2.718
• jQuery version: x.y
• Browser: [all]

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.

Environment

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

• Kendo UI version: 2024.1.130
• Browser: [all]

I have a cshtml page that uses Kendo UI ASP.NET MVC that does the following:

• sends an ajax request to a controller action method,
• opens a new tab using window.open(),
• displays a temporary message to let the user know that something is happening,
• then overwrite the new tab content using the view that is contained in the ajax response.

The view contains one or more grid widgets (the number depends on how many result types were requested) and each grid is set up to export Excel.

The problem is that when window.open() is used to open a new tab, the browser history state is null and the window.location.href is empty with the browser location showing "about:blank". For Chrome and Firefox, this does not cause any issues when exporting excel for the grid.  However, when using Edge with this situation, when the Export to Excel grid toolbar button is clicked and the onExportExcel event is fired,  the browser Open or Save dialog prompt is displayed but the active tab (the one that contained the grid) closes. This behaviour is very undesireable. The ProxyUrl grid excel option does not fire since Edge supports javascript file saving.

A workaround for this situation is to forcibly set the new tab window object location href by using the window.history.pushUpdate function. A code snippet is included below.

let dataModel = {Id = 123571113, Name="jason bourne"};
let jsonModel = JSON.stringify(dataModel);
let curDate = new Date();
let targetUrl = '@Url.Action("Reports", "Report", new { @area = "Reports" })';
let targetWindowName = "something meaningful" + " " + curDate.toISOString();//add datetime stamp to avoid issue where you cannot open a window with the same name as the current window.
let html = "some html content to provide a temporary message to your audience";
let targetWindow = window.open(targetUrl, targetWindowName);
if (targetWindow !== null && targetWindow !== undefined)
{
   targetWindow.document.write(html);
   targetWindow.document.close(); // to finish loading the page
   targetWindow.document.title = targetWindowName;

   //attempt to forcibly update the URL in the history and target window location to fix problem with grid export to excel on Edge browser
   let targetWindowHistoryHref = window.location.href;
   if (oModel.BuildingDesigns !== null && oModel.BuildingDesigns !== undefined && oModel.BuildingDesigns.length > 0) {
       targetWindowHistoryHref += "?oBuildingDesignId=" + oModel.BuildingDesigns[0].ObfuscatedBuildingDesignId + "&BuildingDesignName=" + oModel.BuildingDesigns[0].BuildingDesignName;
   } else {
       targetWindowHistoryHref += "?" + oModel.Target;
   }
   targetWindow.history.pushState(null, null, targetWindowHistoryHref);
}
$.when(
	$.ajax({
		type: "POST",
		dataType: "html", // this is the data type expected to be returned from the controller method
		contentType: "application/json", // this is the content type expected by the controller method
		url: targetUrl,
		data: jsonModel,
		beforeSend: function() {
			console.log(".... submitting report request");
			athena.loader.loading("submitting report request");
		},
		success: function(response) {
			athena.loader.stopLoading();
			if (debugLevel > 2) {
				console.log(".... response = " + response + " : ", response);
			}

			//attempt to populate the target browser tab with the response
			try {
				console.log(".... attempting to open a browser tab and populate it with the HTML response object");
				console.log(".... targetWindow = " + targetWindow);
				//will trigger popup blockers :: targetWindow = window.open("", oModel.Target);
				if (targetWindow !== null) {
					if (response === null || response === undefined) {
						targetWindow.document.body.innerHTML = '';
					} else {
						//completely replace the existing document (not just the innerhtml)
						targetWindow.document.open();
						targetWindow.document.write(response);
						targetWindow.document.close();
						targetWindow.document.title = targetWindowName;
					}
				}
			} catch (ex) {
				// do nothing, just catch when the open fails.
				console.log("error: " + ex.message);
			}
		},
		error: function(jqXhr, textStatus, errorThrown) {
			console.log('.... error :: ajax status = ' + textStatus + ' :: errorThrown = ' + errorThrown);
			console.log('....-- jqXhr.responseText :: \n' + jqXhr.responseText);
		}
	})
).done(
	function() {
		console.log(".... report request has completed");
		targetWindow.focus();
	}
);
