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.

I see a design issue using JsonDataSource and possible nested objects/arrays and providing data in runtime.


Setting up a "root" JsonDataSource is no problem. Also the way setting the json trough parameters.


The issue begins when I want to use a nested array AND the root object. 

Example Json
"InvoiceDate" :  "2024-01-01",
"Positions" : [
"Product":"Product 1",
"Price" : 5.25
"Product":"Product 2",
"Price" : 10.5

The approach using JsonPath for accessing the "Positions" is ok but I have to set up another JsonDataSource with the same json and so that I can access the nested array. 

And now I don't now how to set the Source of the second JsonDataSource in runtime. Setting it using parameters is only possible with one DataSource.

A nice approach would be binding the Source of the second JsonDataSource to the first JsonDataSource with a JsonPath. So we could avoid duplication of data.

Or let us bind to a nested object in a table.

I would like to request an option on bar charts or column chart where the bars can be separated or pushed apart.  The default in Telerik is to place all bar series next to each other, which is visually terrible.  Attached is a sample image below.

I simple spacing option would be great!

Hi Team,

I would like to put in a request for PPT export option for Telerik reports. Our end users want the ppt file to be editable. One of your team members suggested that there is an existing ppt export format, but it is not editable at the moment.  Having an editable option is preferable.

I have projects on .NET Core and I want to use the System.Text.Json serializer that is the new default, but reporting relies on Newtonsoft.Json.



There are two approaches that can be taken right now to solve this:

OPTION 1: define separate endpoints (services, projects) for the different tasks - they can still use the same database layer through a shared project, depending on the architecture you have. This would let you have separated services with the appropriate serializers without custom attributes and code (see below). For example, create a separate project for the reporting REST services.

OPTION 2: add some custom decoration on the endpoints so you can choose which serializer is used on each, you can find some examples here: https://stackoverflow.com/questions/59650907/how-to-configure-two-json-serializers-and-select-the-correct-one-based-on-the-ro - the point being to register a serializer depending on the endpoint based on your own code rather than let the framework put one in for all endpoints.

NOTE: This would be a breaking change.

Reports designed in Blazor Web Designer may have multiple shared data sources, only one of which can be used to bind details section data. That I understand.

A use of a secondary data source can be to provide data to which Report Parameters can be bound, such as providing dynamic localized values for any language and/or region. This I expect to do in every report of mine.

Right now, unless I've overlooked some existing mechanism, in each and every report for each field in such a secondary data source I have to manually create a new Report Parameter, bind it to the desired data source, and at least set the ValueMember to that data source field. This can be very time consuming, especially if there are a large number to be created.

It would seem possible for you to add a data source feature such that use of that data source in a report automatically does this for me for each selected field in the Select Query. That would save me a tremendous amount of design time!

Also, if you reply to this, perhaps you could tell me what constitutes a report's "Inline Data Source"? I have been unable to locate any discussion in your documentation nor any means to actually create one if that were useful to me.

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).

When I drag a data field from a DataSource component to the Report details section in the Standalone Report Designer, the Report > DataSource property is set automatically to the corresponding DataSource component.

In the Web Report Designer, when I drag a data field, the Report > DataSource property remains empty, and the Preview shows an empty report. It would be very helpful the same functionality to be introduced also in the Web Designer.

I would like to have truly bitwise operators for my expressions. Here is my scenario.

I have a bitwise flag in my dataset which defines the status of a value. It can have up to 15 possible values set as true in one field. The issue is, that there doesn't appear to be any way that I can perform a check in my expression.

 I don't want to add 15 additional columns to my dataset that explicitly set these as true as that's total overkill.

The Logical/Bitwise operators article details that there are "bitwise" operators, but these are logic only. This forum post confirms this.

The Uri user function can be selected from the functions list in the expression editor of the designer but when the report is previewed the following error message is shown.

The expression contains undefined function call Uri()

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.

The WPF Report Viewer should support rounded corners.

Currently, I am not allowed to do the following:

<telerikReport:ReportViewer Grid.Row="1"
                            ReportSource="{Binding ReportSource}">
        <Style TargetType="telerikReport:ReportViewer" BasedOn="{StaticResource {x:Type telerikReport:ReportViewer}}">
            <Setter Property="BorderBrush" Value="{telerik:Windows11Resource ResourceKey=PrimaryBorderBrush}"/>
            <Setter Property="BorderThickness" Value="1"/>
            <Setter Property="Margin" Value="5"/>
            <Setter Property="CornerRadius" Value="4"/>

Currently, when you set SplitWorksheetOnPageBreak to True, the Excel Sheet name is formed from the DocumentName or ReportName and the number of the page.

It would be very helpful if the report authors can manipulate these names with Expressions.

Please consider adding an RTF Text Box control to your report toolbar.   Crystal reports has this ability which we've used on many of our reports.  Currently the only work around for changing the RTF data to something that Telerik Reports will print cleanly, is to create a user defined custom function.

Good afternoon,

As per support ticket 1650746, could I please request that Telerik reporting could one day work with minimal APIs as opposed to controllers?

There is also the dependency on Newtonsoft for the JSON side of things. Up until trying to implement reporting, I had removed the Newtonsoft nuget package and was trying to use System.Text instead throughout my project. Perhaps in time, it could be a bit more agnostic when it comes to the provider.

Many thanks,

If there are parameters which are not mandatory, the reports automatically when loaded. In actual scenarios, there may be a lot of data being processed as the parameters may be empty. Developer should have an option on report level, say, AutoRun as true or false. The developer could decide if report needs to auto run.

At the moment, a whole words are removed from text until it becomes short enough to fit in the text box, and this is the only available behaviour.

There should be an option to put ellipsis or clip the text to the textbox width instead (like CSS text-overflow "ellipsis" and "clip").

There's also an older discussion here:
