When a TextBox is deleted from a localized report, if a new TextBox is added, its localized value would be set to the localized value of the deleted TextBox.

When you have some <br /> tags in the HTML, the behavior is different between Kendo Editor and Telerik Reporting.

I attached HtmlTextBox result and Kendo Editor behavior.

i have a very big problem with Telerik Reporting after upgrading from version 2017 R3 ( to the latest version.
I tested also the version (2018 R3, 2019 R1 SP1, 2019 R2 SP1).


After installing the newer version, customers see data of other customers!!


I have a multi-tenant system. All of our report data sources filters by the logged in user TenantId (ASP.NET Identity).

But with newer versions if a second user opens the same report, he gets the data from the first user.


You can find a working repro here:


Clone the project and bring it to run. In branch "master" you find the working version, and in the branch "features/v13.2.19.918" you find the broken version.

I have a report that has a sub-report inside it and it's working just fine.

The sub-report can give one or multiple lines as output for a single row in the master report.
However, when a row's height in the master report is too high (due to the output of other cells, not the sub-report), then the sub-report's output doesn't fill the gap in the master report even when I use anchoring to top and bottom.

When exporting a Table with hierarchically organized dynamic groups, in CSV export only the first detail data row is rendered. Thus, great part of the data is ignored.

The data coming from a JsonDataSource component has null values for a date field. Using the (IsNull, ??, IIf) to check for null does not seem to work. For example: =IIF(Fields.actualWorkHrs Is NULL, "T", "F") always returns false even when there are null values in the actualWorkHrs field.

I've created a table with rows and an alternating style for all rows with an uneven row number

When I start a search for a text / values which are present in even / uneven rows, only the uneven rows (with no background-color) are highlighted

in orange (indicating that the field matches with the search term). All fields in even rows which matches the search term remains with the condional formatted background-color "light grey"

It would have been nice to be able to set a default font, that all object can inherit by default. This will be useful in case one need to dynamically in run-time change fonts.

I used to setup an HTML5 Report Viewer with Report Server. After running the project, the viewer does not load. It seems that it could not find telerikReportViewer script. 

Workaround: Instead of

<script src="/api/reports/resources/js/telerikReportViewer"></script>

use absolute path:<script src="http://yourreportserverhost:83/api/reports/resources/js/telerikReportViewer"></script>

When the report has Bottom Padding, this may cause unwanted page break and generate a new page containing only page footer.

We are using Telerik Report Viewer in our ASP.NET MVC application. I've read the documentation about localizing the report viewer ( and most of the texts are localized now, but there are some other that I can't change.

For example, in the search menu, result list, 'page xx' text.

Can you add this string resource in the resources file?

Prerequisites: .NET Core application that uses HTML5-based report viewer and REST service with Kestrel web server.

When the application is stopped from the command prompt with CTRL+C, it does not stop all the dotnet.exe child processes that are spawn by the application and hangs on "Application is shutting down..." indefinitely.

This behavior might be related with the issue which states that CTRL+C is not forwarded to the child processes.
Perform a detailed examination to see if there is an option to close the processes internally when a shutdown procedure is initiated.

When a textbox had a value and after that the value was deleted, if you try to set a language for the report the following error message occurs: "textbox26.width cannot be parsed as a unit because it does not contain numeric values.

When you set a value of the border width less than 0.5px, then it will be not shown in the HTML report viewer. For that reason consider allowing values which are at least 0.5 px.

When exporting a long report with ContinuousPaper = true in Word format, the output document has text cut.

Based on the limitation explained in the Pagination section in Design Considerations for Word Rendering article of our documentation, Word supports maximum page size of 22 inches wide and 22 inches high. If the page is higher than 22 inches, some data may not be displayed in Print Layout view. So, in Word, a long document couldn't be rendered.

At least, this property could be avoided when printed in Word format.

When a Panel is left docked to the detail section of a report and a table spills to another page, leaving empty space at the bottom (to indicate the table continues), the Panel height is less than the detail section height.

Sometimes the KeepTogether property of the group header doesn't work properly. The content goes to next page even if there is enough space for the items.

After the report is translated we started to change the sequence of parameters. This works fine except the translated texts do not move with it. So parameters have the wrong text.
