The attached sample has a simple table with two row groups, and "header" rows created via "Insert Row -> Outside Group - above".
The groups have "keep together" set.

But despite this, the header rows render at the bottom of one page, with data rows on the following page. This should never happen, I can't think of any case it would be expected (it would be like having "Chapter 2" at the bottom of a page when the text for it starts on the next page). 

I also have a sample with just 1 row group, but with 2 detail rows, and the same thing happens. It only appears to work when there's just 1 row group and 1 detail row.

I am using the HTML5 report viewer and seeing 4 errors in the WAVE tool, along with multiple alerts. See: https://wave.webaim.org/report#/https://demos.telerik.com/reporting/product-sales

Please consider addressing them.

When generating PDF/UA files, we need to have special objects that are read by an internal system but ignored by screen readers. This cannot be achieved with the existing functionality.

It would be beneficial if we could configure reports so that specific objects inside the generated document are ignored by screen readers. For example, by setting a special value to the AccessibleRole property of a text box. 

On export to MS Word, a numbered list that spans two pages restarts at (1) on the second page. Instead, the numbered list should continue numbering from the first page. 

For example, if a list has five items and the fourth item starts on a new page, when I export the report to MS Word, the first three items are numbered (1), (2), and (3), and the last two items are numbered (1) and (2) again.  The last two items should be numbered (4) and (5).

In addition, if an item in a numbered list splits between two pages, the item is numbered twice: once at the beginning of the item and again on the first line that appears on the next page. The line at the top of the second page is numbered (1). This second number should not appear.

The attached file shows both these issues.

I am using the Standalone Report Designer for .NET to open a code-based report from an application that was migrated from .NET Framework. Before the migration, function calls defined in the designer.cs file were preserved and evaluated at runtime as expected. However, after migrating to the code-based reports functionality supported by the Standalone Report Designer for .NET, these function calls are evaluated immediately during the report import process, and the resulting values are then serialized and stored in the report definition.

It would be nice if the function calls were preserved in the imported report, allowing them to be evaluated later at runtime, as their return values may change depending on the execution context.

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).

Our clients enter information using the radeditor and in many cases want to embedded tables and graphics into their text.  Using your reporting tool there is no way to print this information.  I know you have suggested using your table and image tools, but that doesn't work when you are dealing with freely formatted text so the existance and location of the tables and images cannot be predicted.

The Initialize method in ReportViewer.cs is called from both the OnLoaded and OnApplyTemplate methods, which in turn calls the AttachModelEventHandlers method. This leads to it adding the event handlers to the model twice every time it is loaded. The DetachModelEventHandlers is only called once (in the OnUnloaded method), so if you keep unloading and reloading the control, it adds 2 event handler invocations but removes only one. This means each one is called at least twice (if you have only loaded the control once), then 3, 4, 5, etc times if you keep unloading and reloading it.

I've worked around this by adding code to my wrapper class to prune the duplicated handlers for now, but this needs fixing in the base code.

I have updated to version 19.2.25.813 of Reporting, and when I try to build a project that has Reporting references, I get the following warnings:

Telerik and Kendo UI Licensing warning TKL102: Your current license has expired and is not valid for Telerik Document Processing Libraries version 2025.2.807.20.

There are no Telerik Document Processing dependencies in my project, but I still get the warning.

When using the "Close"/"Close All" options when a report has unsaved modifcations, a warning is shown, but you are forced to save the report or close the window/tab to leave definition file unmodified.

A "close and discard changes" option is helpful and convenient - one can cancel some edits without hoping that a bunch of "Ctrl - Z" presses will clear everything, refer to one report without concern about accidental modifcations (can be editing others), etc.

The Web Report Designer does not entirely comply with CSP standards, necessitating the use of the 'unsafe-eval' directive in our CSP policies to enable its functionality.

This directive poses significant security risks and undermines the purpose of implementing CSP in the first place. Please remove this requirement.

In the standalone designer, it would be helpful if you could drag and drop the column headers to reorder.  At present you have to add a new column and delete the old one, remembering to copy all properties.

I set globally the culture on the Linux Ubuntu Docker Container. Interestingly, the negative currency with en-US and fr-CA was displayed with the '-' sign rather than in brackets.

This was reproduced even in the values set with the Text Function FormatWithCulture(cultureName, format, args). The function displayed wrong formatting also on Windows, even in the Standalone Report Designer for .NET 8.

When the global culture on Windows was en-US, the negative decimal value formatted without the FormatWithCulture function was displayed correctly in .NET 8.

In the .NET Framework, the negative currencies were displayed as expected in all scenarios.

I have linked also a muted video showing the issue.

I have been forcing my webservice data source into a workable solution for making GraphQL requests. Right now in order for us to use GraphQL, we have to build out the request manually with a string such as the following:

{"query: "query GetSomeResult($input: Int!) {result {id name}}",
"variables": "{"input": @parameter}"
}

While this is a normal way to hand craft a GraphQL request, the issue I have is that it shouldn't need to be that hard. Also I get no intellisense or suggestion in regards to the data returning. This means that when I try to bind data to a text box, I have to visually validate that the [=Fields....] is actually correct by looking at the GraphQL query and at the code base. I would love to see the ability to to just say have a set of standard api technologies we could implement from such as GraphQL queries, GRPc queries, or any other contract style request. I would expect that the data source logic would be smart enough to parse the query (at least for GQL) and be able to provide reccomendations.

Also a major issue we have had is in being able to pass that data source to subReports, or dealing with any nested objects such as a user.address.addressLine1 would not be able to be found if address is a nested values like the following

user: {
  address: {
    addressLine1
  }
}
