In my report, there is a Table with one group and PageBreak set to After for the group. If the property ColumnHeadersPrintOnEveryPage is with the default value False, in Interactive view there are three pages generated, one for each group, which is correct.

If I set ColumnHeadersPrintOnEveryPage to True, the number of pages increases to four in the Interactive view mode. There is an additional page break introduced in the last group.

Hi there,

Adding an external style sheet to a report in a report-book triggers an error when previewing the report book, "Object reference not set to an instance of an object" 

I've attached the bare minimum project to reproduce the error.

I've also tried upgrading to R3 2020

Cheers

Steps to reproduce:

1. Add a ConditionalFormatting to one report item (for example crosstab).

2. Select the first existing rule.

3. Click "Copy Selected Rule"

4.  Click "Paste Rules" - nothing happens.

You can also see the attached video which demonstrates the problem.

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.

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.

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.

Sometimes the following unexpected behavior can be observed with the WinForms report viewer.

Steps to reproduce:

1. Run the WinForms application;

2. Select a value for the parameter and click on Preview.

The window's size is decreased.

In Visual Studio Report Designer Preview, Use https://play.google.com/store/apps/details?id=com.teacapps.barcodescanner and other apps to scan the barcode(such as attachment Visual Studio Report Designer Preview.png), but after exporting the PDF, The first barcode scan is correct, the result of the second barcode scan is the content of the first barcode(such as attachment Exported PDF.png), Attachment BugDemo.zip is my project, How can I fix this problem, thanks.

When displaying a report in the WPF Report Viewer, with a TextBox in the page Footer, using the Expression:

= Format("Page: {0} of {1}", PageNumber("groupPerson", Fields.PersonId), PageCount("groupPerson", Fields.PersonId))

The whole report is displayed and printed correctly.

When a single page is printed, for example: Page 3 of 5, using the Print Dialog, the page number is incorrectly printed as: Page 3 of 1
