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.

Make the Design-Time parameter values of the WebServiceDataSource editable through code.

Currently, the design-time values can be edited only by the report designers or by saving the report with the TRDX extension and editing the XML.

In the XML, to change the design-time values, you may edit the ParameterValues property which is a string. 

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.

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.

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.

Hi,

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

Thanks!

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.

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.

Reports.zip

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.

Hi

I need to adjust line spacing in multiple line textbox but currently there seems to be no way to do that. Please add this feature!

Thanks

At the moment it's only possible to have your reports in old-fashioned projects.

It should be possible to add/design reports to SDK-style projects. That should work no matter what target framework is (.NET Core, .NET Standard or .NET Framework).

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.

Hi, While the Report Designer exports tags to the PDF (with Accessibility enabled), the tags exported are not fully compliant with PDF/UA or 508 requirements. For example, my document has several hundred pages, each with two or three data tables on them. While the tags get exported, they are only Paragraph tags, and NOT Table tags. Is there a way to designate Table Header Rows, Header Columns, and Data Cells in Telerik Reporting such that upon export to PDF they get tagged properly?

What's the long-term plan for supporting Linux and Telerik Reporting? The dotnet design team is looking to remove support for System.Drawing.Common on Linux platforms. They're recommending compiler warnings in .Net 6, and full PlatformNotSupportedExceptions in .Net7
