I am trying to add HtmlTextBox to my report. After double-clicking on the HtmlTextBox, instead of opening the HTML editor, an error message appears 

And after that, it is not possible to delete any element of the report

When the EnableAccessibility PDF device info setting is set to true in the RuntimeSettings of a report, the text set to an item in the AccessibleDescription report item property is not respected.

For example, a PictureBox with AccessibleDescription set to "Text1" will have the "Picture Box" alternate text set in the exported PDF instead of "the Text1" string.

Recursive sub-report with hierarchical data. When expanding/collapsing, all nodes get expanded or collapsed.

I would expect only the selected node to be expanded/collapsed.

For reference, the report from the How to represent hierarchical nested data in report recursively - Telerik Reporting KB article was used as a base 

Using a Toggle Visibility action to expand/collapse recursive SubReport results in the "Node should be found among parent nodes" error. The recursive SubReport renders fine without the action.

The report from the How to represent hierarchical flat data in report recursively - Telerik Reporting KB article was used as a base.

The source of my SubReport was in a nested class and in the preview of the main report I received the error "Invalid report type" although the same nested class was successfully discovered in the VS designer with the assembly-qualified name 'Test.Class1+DetailReport1, Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

When I tried using a class (without a nested class, e.g., 'Test.DetailReport1, Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null') then I could get the subreport to render within the main report.

It could be the syntax for the qualified name is not handling nested classes. 

Attempting to delete a group section from the Explorer tab in the Web Report Designer leads to the following error being thrown in the browser console:

Uncaught (in promise) Error: Rollback inner transaction
    RollbackTransaction http://localhost:51863/api/reportdesigner/designerresources/js/webReportDesigner-16.2.22.1109.min.js/:9
    Rollback http://localhost:51863/api/reportdesigner/designerresources/js/webReportDesigner-16.2.22.1109.min.js/:9
    execute http://localhost:51863/api/reportdesigner/designerresources/js/webReportDesigner-16.2.22.1109.min.js/:9

As a result, the section is not deleted. However, the section can be deleted by deleting the corresponding report group from the Properties area(Data section) in the Web Report Designer.

In such a case, the following exception is thrown

Inner exception: System.ArgumentException: The path is not of a legal form.
   at System.IO.Path.NormalizePath(String path, Boolean fullCheck, Int32 maxPathLength, Boolean expandShortPaths)
   at System.IO.Path.InternalGetDirectoryName(String path)
   at Telerik.Reporting.Interfaces.FrameworkDependentDeploymentModel.GetDirectory(Assembly assembly) in

The likely reason for the error is that since the assembly is loaded from the bytes, and not from a path, the assembly.Location in the Telerik.Reporting.Interfaces.FrameworkDependentDeploymentModel.GetDirectory method is Null.

In some scenarios, the PrintOnLastPage functionality of the page sections does not work as expected.

For example, if the report with PrintOnLastPage is the last one in the report book, on the last page of the report book, which will also be the last page for that report, a page section will still be rendered even if PrintOnLastPage is False.

This happens when the default PageNumberingStyle.Continue is used by the reports.

On the other hand, if the last report has a PageNumberingStyle.ResetNumberingAndCount, the page section will not be rendered if PrintOnLastPage is set to False, so in this scenario, it works as expected.

I wanted to add some white space between the TOC text and the leader symbols in my TOC. Here is the default TOC when I don't use whitespace:

I tried the following Expression:

= Fields.group1 + "            "

Here is the result - the TOC text of the first level was displaced as if the added whitespace is before the text:

The workaround I found is to add one LeaderSymbol at the end of the whitespace string:

= Fields.group1 + "            ."

Still, it seems that there is whitespace trimming that is not correctly implemented for the TOC section.

When a report has a report parameter using a data source, that is visible and has AllowNull set to True, if the value initial value is invalid, no report parameter widget is loaded at all for this parameter.

If this is the only report parameter, the parameters area is not rendered at all, even though the toolbar indicates that it is active.

The issue can be reproduced by loading the attached report in the native Blazor Report Viewer.

Hi,

Have the possibility to have the "Select Case" or "Switch" function in the expressions.

Thanks!

We separated our data objects into a library project and then referenced it via the web.config. It works as intended, both in the designer and during data retrieval, but to update the dll with more objects we have to restart the whole site.

It would be very useful if we could substitute our assemblies without restarting the website.

The Telerik.Reporting.Report class has the property ExternalStyleSheets which is an ExternalStyleSheetCollection.

This collection consists of objects of the type ExternalStylesheet which has private Name and ResourceKind properties.

Would be great and make sense to make these properties public since that would help when the external stylesheets need to be resolved dynamically, though a custom IReportSourceResolver for example.

I want to export a Report as a PNG image with transparent background.

I set the Style > Background to Transparent for the PictureBox in the detail section, for the Page and Detail sections, for the Report itself, and for Report > PageSettings. The PNG image is still rendered with white background.

We use Reporting REST Service to generate our reports. When exporting to BMP, EMF, GIF, JPEG, and PNG which are all multi-document formats, the downloaded documents are corrupted and cannot be opened in Image viewer.

The TIFF image, which is a single document is exported and opened as expected.

Using the Npgsql data provider of version 6.0.7 leads to the following error when there is a DateTime SQL parameter:

Can't write CLR type System.String with handler type TimestampTzHandler or Can't write CLR type System.String with handler type TimestampHandler.

This error is thrown only on Design-Time because the Design-Time value for the SQL parameter does not respect its selected DbType and is instead always a string.
