we need to have complete End User Tutorial for Web Report Designer, where all the excel like features need to be demonstrated.

including Pivot etc.

With the standalone desktop designer it would be great to be able to override the version of the report file so that it can be used in dev/test/historical environments where we are still referencing an older version of the Telerik Reports libraries.

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).

As soon as we enable Accessibility, the parameter area will not be displayed anymore. You can reproduce the issue with the Demo Project when using a Custom Parameter Editor.

The HTML5-based report viewers use the following navigation icons.

• Arrow with a line to navigate to the next/previous page.
• Double arrows to navigate to the first/last page.
  

This is unintuitive and inconsistent with the desktop and native report viewers.
The navigation icons should instead be:

• Single arrow to navigate to the next/previous page.
• Arrow with a line to navigate to the first/last page.
  

Opening the .NET version of the Standalone Report Designer through a TRDP/TRDX/TRBP file changes its default working directory and external assemblies that are added to it cannot be loaded. 

When the input data of a pie chart is such that some of the series are insignificant enough not to be drawn on the surface area, a DocumentRenderException with the message "The operation was canceled" is thrown by the Reporting engine.

Enlarging the pie chart or hiding/removing its data point labels clears the error. 

Adding the "Telerik.ReportViewer.WinUI.Themes/Themes/Generic.xaml" theme to a WinUI project causes existing AppBarButtons to grow in size because it overrides the AppBarButtonContentHeight setting.

The report viewer theme should not override the styles of the default WinUI controls.

I have a problem with the current version in a Linux container using 2024.1.30 and 18.0.24.305 version of reporting. I only get this when I'm attempting to produce multiple reports at the same time.  It's the same issue regardless of whether it's running as a hosted web service or if I'm running as a server based blazor app.

DockerBlazorApp Error: 0 : An error has occurred while rendering the report: System.InvalidOperationException: Operations that change non-concurrent collections must have exclusive access. A concurrent update was performed on this collection and corrupted its state. The collection's state is no longer correct.

When I render one of my reports I receive the error message  “A generic error occurred in GDI+”.

I figured out that one HtmlTextBox receives quite a long HTML from the data source - exceeds 32 768 characters. In my experiments, the error starts appearing if the text is longer than 32 775 chars.

In this case, the Reporting engine shouldn't throw a misleading GDI+ error but instead throw a more specific exception.

The current version(R3 2023) of the MsSqlServerStorage implementation uses the old System.Data.SqlClient data provider which forces to use a different connection string from my application because keywords such as 'authentication' are not supported by the older provider.

If you set the WinUI viewer's ViewMode to PrintPreivew in the XAML or the code, the toolbar button's state and value don't change. Hence, even though the report is displayed in PrintPreview, the button for switching the ViewMode is still showing 'Switch to PrintPreview' and is not highlighted. When you click it, the report is displayed in Interactive View, the button becomes highlighted and the tooltip states 'Switch to Interactive mode'.

If cells grow or shrink, if there are hidden cells, any time a report section grows vertically, the next section/table is not respecting the growing of the previous item and text prints in the wrong spot or the table overlaps the previous table.

A potential workaround is to manually convert the troublesome tables to lists where possible.

The WebServiceDataSource wizard in the Web Designer doesn't let you construct Expressions for the Parameter values. The same functionality is present in the Standalone Report Designer.

The SqlDataSource Wizard of the Web Designer also allows the creation of Expressions for the Parameter values.

It would be convenient if the report creators were allowed to create the Expressions for WebServiceDataSource parameter values directly in the wizard. Currently, you need to type or paste the Expression manually.

I have denied the permission to use the Asset Manager in the configuration of the service of the Web Report Designer. This is generally respected and I do not see the option to open the asset manager from the main menu but when I try to set an image to a PictureBox item, I still see the option to add it from the assets and the button is also clickable.

With that being said, the permission is respected on the server and I get an error about not having permission to use the Asset Manager when I click on the button. Still, it will be better if the button is removed from the UI altogether when I have disabled the assets.

Coming from having developed many SSRS reports one thing I think telerik is missing is a nicer visualisation of row and column grouping in a table. SSRS does this really well as shown in the screenshot below where we can easily see which rows belong to the detail and 2 other groups.

I think this would be a very useful addition to the telerik designers!

 

The RTF rendering automatically switches to the Tables rendering mode whenever a Crosstab/Table/List is detected in a report. This rendering mode throws an exception whenever the report contains PictureBox with one of the following sizing options.

• Center
• Normal
• Stretch
• ScaleProportional

The RTF export should work with all PictureBox sizing options regardless of the rendering mode.

To work around the issue currently, one can either force the rendering engine to use the Frames rendering mode using the RenderingMode device information property or set the Sizing property of all picture boxes in the report to AutoSize.

 

Currently, the Map's TileProvider UrlTemplate property may be set only to a hard-coded string. It would be very useful to be configurable as an Expression to allow for dynamic values.
