If there is a pageMode option, An error event is fired at initialization, even if no error occurred.

The problem can be reproduced with the HTML5 demo:

$("#reportViewer1")
                .telerik_ReportViewer({
                    serviceUrl: "api/reports",
                    reportSource: {
                        report: "Telerik.Reporting.Examples.CSharp.ReportCatalog, CSharp.ReportLibrary",
                        parameters: {}
                    },
                    viewMode: telerikReportViewer.ViewModes.INTERACTIVE,
                    pageMode: telerikReportViewer.PageModes.SINGLE_PAGE,
                    scaleMode: telerikReportViewer.ScaleModes.SPECIFIC,
                    scale: 1.0,
                    enableAccessibility: false,
					sendEmail: { enabled: true },
					ready: function () { debugger; },
					error: function (e, args) { debugger; }
                });

The FreezeColumnHeaders functionality doesn't behave properly when Action is set on the header. The white background color of the headers which we need to see in the viewer when the FreezeColumnHeaders property is set to True is missing. Please, check the attached project which reproduces the issue. If you reset the Action property of the ID header, then the FreezeColumnHeaders functionality works as expected.

Hello,

What are the future plans for reporting on .net framework ?

Currently it works on the old .net track → 4.6 but not for .net core.

.net 5.0 is planned november 2020

It would be nice that we can have this on 1 .net framework version.

I had compare crystal report and Telerik report on rendering similar dataset. (LARGE dataset)
Crystal report renders much faster on showing the initial page (viewer) by almost 50% compare to Telerik html5 viewer. (almost 10,000 pages)
Crystal report renders much faster on generating PDF file by also 50%.
Also Crystal report telling the total page on the initial rendered page., while on Telerik report (html5 viewer) it on shows pages that are already cache (and show caching progress.) It would be nice if it show the total pages then shows in the status notification the progress of caching.

With the following HTML 'underline' is applied to the whitespace run-time but not design-time.

<span style="text-decoration: underline">PAYMENTS ONLY        </span>TO:

The whitespace is reduced to a single space irrespective of its position in the text. For example the following content:

PAYMENTS          ONLY                    TO:

is displayed as shown in this screenshot.

When an HTML content is placed in nested block elements, it is displayed differently from the way the browser displays it.

For example, the following HTML:

<div><p>htmlTextBox1</p></div>

is vertically displaced compared to the same content when not wrapped in another block element:

<p>htmlTextBox1</p>

This image demonstrates the difference.

Hello, 

It would be nice if Telerik Reporting supported an organizational chart type like in ASP.NET AJAX. See the following image for a reference. 

I have a few reports in which I have a multivalue parameter that renders a ListView control.  However, when the user clicks on "Select All", only the 1st value is sent to the server.

Also, if some of the values have default values when defining the Report parameter and one of them is the 1st value, then ALL values are pre-selected when the Report renders. However, when the user clicks "Preview", again only the 1st value is sent to the server.

The above happens when I reference Kendo ( kendo.all.js) 2020.2.513 in the project. With Kendo 2020.1.114 the viewer works as expected.

The NuGet package Telerik.Reporting.Services.HttpClient has a package dependency to Microsoft.IdentityModel.Clients.ActiveDirectory 2.22.302111727, which is incompatible with .NET Core.

When referencing the Telerik.Reporting.Services.HttpClient NuGet package in a .NET Core project, an incompatibility warning appears.

Due to specifics in font resolving mechanism on Linux, some fonts cannot be resolved correctly when the font name includes the font-face name - for example, the name "Noto Sans CJK TC Regular" would resolve the font-face "Noto Sans CJK TC".

When using a custom IReportResolver, it gets invoked to resolve the main report but does not get called for any sub/child report. This generates inconsistent handling of the report resolve and also makes it hard to have a single repository for report templates.

When there are both ASCII characters and non-ASCII characters (such as Chinese) in the text box, the position of line wrapping in Linux Docker is incorrect. Some of the data get lost.

More information can be found in the forum thread TextBox's line wrap position is incorrect in docker.

Sometime the design of the report is too complex (the graphic design) and using a table for suppressing repeating values is not possible.

It would be really nice to have the Suppress if duplicated property in the textboxes so as to be able to use it in the detail band, also it should repeat it only on the first detail of a new page.
