Hi Telerik team

I'd like to implement customer specific colors based on a report variable or database field.
Currently it looks like the color properties only give us a color picker but does not support using an expression, is this correct?

As for context, I do not know the color in advance and it is used at 100+ different objects.

Same problem with conditional formats

Please let me know how to choose colors based on expressions.
If this is not possible yet, I'd like to request it as a new featur.

Best regards,

Having the ability to be able to set properties of the HTML5 report viewer globally would be a nice addition. This functionality already exists for other controls and it would have saved me lots of work when I needed to set a template url to over 50 pages.

Hopefully this gets implemented and saves someone else some of their time and if so, your welcome :)

If you embed an iframe that points to a report viewer on a page, and the page is hosted on a web server on a different origin, the print functionality does not work.

Consider implementing a workaround to enable it.

We have reports rendered through the Native Blazor Report Viewer.

Consider adding a file attachment option in the Send Email dialog for report viewers.

<dependencies>
  <group targetFramework=".NETFramework4.6.2">
    <dependency id="Newtonsoft.Json" version="13.0.1" />
    <dependency id="Telerik.Reporting" version="[19.0.25.313]" />
    <dependency id="Microsoft.Net.Http" version="2.2.29" />
  </group>
  <group targetFramework=".NETStandard2.0">
    <dependency id="Newtonsoft.Json" version="13.0.1" />
    <dependency id="Telerik.Reporting" version="[19.0.25.313]" />
  </group>
</dependencies>

The package "Microsoft.Net.Http" is with the latest available version and depends on:

Microsoft.Bcl (>= 1.1.10)
Microsoft.Bcl.Build (>= 1.0.14)

The package "Microsoft.Bcl" is indeed deprecated.

Is it possible to get descriptive information exposed for the ReportsControllerBase swagger endpoints? do they exist?

Notice how the About and files endpoints have information next to them:

Like-wise how the files endpoint has descriptive parameters:

In the Telerik Reporting Designer there are already quite a few Chart Diagrams included but the one that is missing is a Sankey Diagram. This is already integrated in the Charts in KendoReact for example and I would like to request to also add this in Telerik Reporting because I think it would be a great addition and also we would for sure need this.

Thanks,

Hello Telerik Team,

I would like to suggest a feature enhancement for the Web Report Designer that would allow dynamic configuration of design-time parameter values during initialization.

Currently, design-time values for report parameters are embedded within the report definition and can only be set manually using the Web Report Designer interface. While runtime parameter values work perfectly and can be passed dynamically through code, not being able to dynamically set design-time values causes significant limitations—especially during the report design process.

My Use Case:

In my application, I load data from a dynamic web service endpoint, and the service domain needs to be set at runtime. While this works fine during preview in my ASP.NET MVC project (where I pass the URL dynamically using report parameters), I run into issues when designing reports:

• During design time, the URL has to be manually entered into every Web Service Data Source just to fetch the model fields and avoid errors.

• If the domain name changes (e.g., due to staging/production environments), I must manually update the domain in every report and each Web Service Data Source, which is both time-consuming and inefficient.

• This becomes even more tedious in large projects with many reports and data sources.

So, my question is: Is it mandatory to pass design-time values (like the service URL) manually just for design-time purposes? If not, it would be incredibly helpful to have a way to supply these values dynamically during the Web Report Designer initialization, perhaps via a configuration option or external context.

Petar from the Telerik team mentioned that this would indeed be a valuable feature and encouraged me to submit this suggestion. You can view our discussion here: 🔗 Dynamic Web Service Domain Configuration in Telerik Report Designer Server

This capability would make designing reports much smoother and far more maintainable, especially for applications that rely on dynamic, environment-specific configurations.

Thank you for considering this request, and I appreciate your continued support and guidance.

Screenshots are also attached for quick reference, though they are already available in the forum link above.

Best regards,
Prabesh

Sometimes I need to be able to allow the users to choose not only the date but the time as well when displaying DateTime report parameters in my reports. There is no out-of-the-box functionality to achieve this and I am forced to implement custom parameter editors -  Creating and Using Custom Parameter Editors in HTML5 ReportViewer - Telerik Reporting.

I should be able to set whether a DatePicker or DateTimePicker widget should be used for DateTime parameters from the report viewer's initialization options, such as how I can change the editor for single/multi-value parameters in the HTML5 report viewers - HTML5 Report Viewer Options Overview - Telerik Reporting.

Currently, there is design-time support for the WinFoms Report Viewer in the VS Designer only when the project targets .NET Framework.  I need this functionality to be supported in .NET WinForms projects as well.

Just like the HTML5 Report Viewer, it will be easier to embed the Web Report Designer in an application if it wasn't necessary to manually add the kendo script to the page.

I have a use case which requires me to record data whenever a report is printed. In pursuit of this, I am trying to replace the build in Print() tool and replace it with my own.

I have read this documentation which shows how to remove and reorder the buttons well enough, but it does not support adding a new tool all-together. Javascript event listeners will not work for me because ultimately what I want to do is accomplish a database write, which would be insecure through javascript.

 I have been able to establish a workaround by following this documentation and creating a button *outside* of the ReportViewer, however, I would still like to find a way to put the button inside of the ReportViewer toolbar if possible. 

I often need to have the same Report Parameters in different reports, including the main and its subreport. Currently, I need to add the parameters manually.

It would be very useful if we could copy/paste Report Parameters between reports.
