The timestamp field of MSSQL databases is recognized as byte[]. When using the Query Builder of the SqlDataSource wizard of the Report Designers, it tries to convert this byte[] to an image, which fails as the field is not a valid image. This doesn't obstruct the set-up of the data source. The query can also be executed successfully.

If you introduce a Column group in a Crosstab and set its PageBreak to After, it won't be respected.

When the report is exported to PDF, everything is as expected. When the report is exported to DOCX or XLSX, then part of the report is dismissed.

It would be nice to translate the Web Based Report Designer to my local language.

Source control is already doing this for me - but it also picks up the change so every time a .trdp.bak file gets created, I have to manually remove it.

It would be nice to add an option to the settings that specifies whether or not the .bak file should be created.

Telerik Reporting needs a comments feature in the expression window. Some of our expressions are complicated and it would be great if we could put a comment in there for future reference.

Something like // or #

And yes, I've seen the iif(true=false...) method which is... not great.

The JsonDataSource does not accept parameters, which doesn't allow filtration, for example, based on a Report Parameter value.

I have an core web app that works fine running from VS 2019 and IIS Express. However, if I run it under a docker windows container, there's an error when deserializing the xml .trxd file.

Exception thrown: 'System.TypeInitializationException' in Telerik.Reporting.dll
Exception thrown: 'System.Reflection.TargetInvocationException' in System.Private.CoreLib.dll
Exception thrown: 'System.Reflection.TargetInvocationException' in System.Private.CoreLib.dll
Exception thrown: 'System.MissingMethodException' in Telerik.Reporting.dll

This is only happening when running in a windows docker container.

Please do some testing with this configuration.

New development is being done with net core 3.1 and netstandard 2.1 and we can no longer create reports in the Report Designer using the ObjectDataSource.

Seems like it's time to update the standalone Report Designer for these new standards.

If I run the angular report viewer within my main page, all is well. However if the report viewer is hosted in a <p-dialog> (or <p-overlaypanel>), the report does not render (even though data is loaded and the report can be exported). To confirm this, I even have the report visible in a <tr-viewer> on the main page behind the dialog and load them at the same time.

If the dialog is not visible when the main page opens, then the report viewer toolbar is in a column on the left, and is not operational. (see attached)

If the dialog is visible when the main page opens, then the toolbar appears at the top and functions normally. (see attached)


<tr-viewer #rptViewerBody


<p-dialog modal="true"

        <tr-viewer #rptViewerDialog


In the code, I tried both of these container styles. The result for the dialog was that relative position rendered the toolbar (top or left), but absolute position rendered nothing at all (height became 0)

this.viewerContainerStyle = {
      position: 'absolute',
      top: '0px',
      left: '0px',
      right: '0px',
      bottom: '0px',
      ['font-family']: 'ms sans serif'
this.viewerContainerStyle = {
      position: 'relative',
      width: '1300px',
      height: '1300px',
      ['font-family']: 'ms sans serif'


using @progress/telerik-angular-report-viewer": "7.19.718"

Would be great if your upgrade wizard would look for web.config and web.config.* files to update rather than just the web.config file.

When I place an HtmlTextBox in a table column and set its top padding, the padding is respected when previewing in the designer and when the report is rendered in PDF. When previewing in the Html5 Viewer the padding is ignored.

It would be nice to control the report loading animation during a report viewer refresh. We are refreshing a report every x seconds and it appears to be flickering during a refresh.

Thank you.

The standalone report designer needs config settings for

  • Default Font Name
  • Default Font Size
  • Default Font Color
  • Default Page Settings
    • Margins
    • Unit of Measure
  • Snap To Grid

I find that I have to set each of these for every report. 

Please add these,

Please add to the Telerik reporting step line chart the same functionality that exists in the kendo ui step line chart.   There is an attribute for justified = true that allows the line to step directly to the marker rather than having them placed in the middle of the step.  Please see the attached images for the current result vs the desired result.

I have been working on some reports that require multiple tables on a single page. This limits the space columns have for data being bound to fit and results in text wrapping. I made a support ticket asking if there was a way to have dynamic column widths. I hoped to find a way to get table columns to change their widths depending on the data being bound to the table, while still maintaining the overall width of the table. My idea was to have it distribute the space (change the column width) to best display data and avoid text wrapping if possible. 


Attached to this request are some PDFs. One of them ("Current Report") shows that some data is either cut off or uses text wrapping. The other attached PDF shows the closest I could get to an acceptable layout, given our clients requirements and what our design team wants the reports to look like.

Thank you!

There is an issue where the search window that opens from the Report Viewer tool bar does not allow for deleting text from the search string input box using backspace.

The keyboard command provider seems to have many other keys covered for the intended behavior, but backspace does not seem to be handled appropriately.

I put a ReportViewer in an application and VisualStudio inserted the required MergedDictionaries.  I updated them to the Green theme and added the Green reference, now I get a XAML error stating Cannot find resource named 'RepeatButtonStyle.'  I comment out this line in my App.xaml file:

<!--<ResourceDictionary Source="/Telerik.ReportViewer.Wpf.Themes;component/Themes/Green/Telerik.Windows.Controls.Navigation.xaml" />-->

the error goes away and my XAML designer works again, but the navigation section of the report viewer has the incorrect theme applied.

I looked in the copy of the file that is on my computer located at:

   C:\Program Files (x86)\Progress\Telerik Reporting R2 2019\Wpf\Themes\Green\Telerik.Windows.Controls.Navigation.xaml

On line 8831 there is a reference to a Static Resource named RepeatButtonStyle.

<Style x:Key="TabbedWindowScrollButtonStyle" TargetType="RepeatButton" BasedOn="{StaticResource RepeatButtonStyle}">

I assume this the culprit?

There was a similar issue in February.

In my report, I use font SimSun to display Chinese, when preview it's OK, but after click print, an exception is thrown.
