I have a table with all of my columns sortable. 

When I add the sorting button using the Interactivity feature, the buttons are all left aligned. It is confusing when trying to figure out which button sorts a column. See the attachment.

I'd like to be able to move the sorting button left or right.

Currently, you can edit report in the web report designer only from the specified folder in the ReportSourceResolver or implement custom IDefinitionStorage as explained in the How to implement a report definition storage article. For that reason, it would be nice if you can set the report's folder dynamically out-of-the-box.

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.

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.

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

Breaking change: System.Drawing.Common only supported on Windows - .NET | Microsoft Docs

Currently, if you use an Expression to change the parameter's Text, it will be correctly evaluated only the first time when the report is rendered. Let's say you have 2 parameters- Parameter1 and Parameter2. The Text property of the second parameter is based on the Value of the first. However, if you change the value of the first parameter, then the Text of the second will not be updated.

Please, add the option to set the report of the web report designer dynamically. Similarly as for the HTML5-based report viewers. For example https://docs.telerik.com/reporting/html5-report-viewer-howto-custom-parameters

I have a following default code in a html file for a web designer.

$(document).ready(function () {
                persistSession: false,
                toolboxArea: {
                    layout: "list"
                serviceUrl: "some url",
                report: "some_report_name",

I have also a custom report storage implemented from IDefinitionStorage, where I have a GetDefinition("some_report_name") method implemented in a custom way. In order to do that, I need to send additional parameters from a web designer (html code provided previously) but don't know how to do that. 

For example, I need to open SalesInvoice.trdx file and I do a following: report: "SalesInvoice.trdx". If i need to send additional parameter, let's say some kind of token, there is no good place to send it. As a work around, i am doing report: "SalesInvoice.trdx&token=123". The problem with this, it is appearing in a title of a web designer and I don't want that. In an attachments, there is a screenshot where it looks good with a simple name and the one which has a token in it.

So, the question is, can I send other parameters as well from a client side of web designer to the server like parameters or so?

In a HTML5 ReportViewer we can send report file name and parameters as a reportSource like this:

                    serviceUrl: serviceUrl,
                    reportSource: {
                        report: reportUrl,
                        parameters: reportParams,

Can we do the same? Or how can I do that?

We use WebServiceDataSource with OData query in our reports. Sometimes OData can through an exception.

In our case, we have added Web Service DataSource and set this OData query for its Service Url:


If you see the query, it is selecting "ProductName1" property of "Product #1". But "ProductName1" property does not exist (correct property name is "ProductName"). When we use Postman for the OData query above, it shows an error which you can see from attached picture (ErrorWhenWeUsePostman.PNG, "Could not find a property named 'ProductName1' on type 'NorthwindModel.Product'"). From the second picture (TelerikReportingGeneralError.PNG, "An error has occurred... Response status code does not indicate success: 400 (Bad Request).") you can see the result of our test report (in html5 report viewer) that has the same OData query.

The question is when we preview our report (in html5 report viewer) how can we show the error message that OData sent instead of showing Telerik reporting general error?
Instead of this message:

An error has occurred while processing Report 'TestReportWithWebServiceDataSource': Response status code does not indicate success: 400 (Bad Request).

This OData error message should be handled and shown on browser (html5 report viewer) when previewing report:

Could not find a property named 'ProductName1' on type 'NorthwindModel.Product'

FYI: We are using Telerik Reporting version

This is my post on Telerik forum related with this: How to get internal error message from Custom Report Resolver

Thank you,

We are using the external style sheet file (StyleSheet.xml) when designing our report from Web report designer. We want to see our style sheet applied on our report when we see the report from Web designer in design mode. In Preview mode it is working fine.  But the problem here, it is not working in Design mode.

See the attached pictures. You find our problem on the picture ExternalStyleInWebDesigner-DesignMode.PNG

Is there any solution or a feature request needs to be created?

FYI: External style sheet is working in Standalone report designer in both design and preview mode.

When a report is open and the user click on the "generate" button, a busy indicator is displayed and the user can continue to use the application during the generation of the report. The UI thread is not blocked.

But when opening a view with the ReportViewer, the UI freezes during the initial connection to the remote engine, until the report is ready to be generated. If the report has parameters requiring a database query to load the available values, it freezes for a few seconds.

Would it be possible to load the ReportViewer instantly, then display a busy indicator until the report is ready, without blocking the UI thread ? (exactly as for the generation of the report)

The Angular Report Viewer uses the jQuery npm package, while the Web Report Designer uses jQuery.min.js directly from a CDN. If you try to use both Angular Viewer and JS Web Designer in the same application there will be a conflict while loading jQuery twice from the different sources. This is why the Angular Report Viewer cannot be loaded together with the JS Web Report Designer in the same application. The KB article Displaying the Web Report Designer in Angular application provides a Known Issues section at the bottom where this problem is explained:

"Telerik Web Report Designer could not be integrated into Angular application together with Angular Telerik Report Viewer. That is why this article shows how to use the Telerik Web Report Designer in angular application with jQuery-based HTML5 Telerik Report Viewer."

When using multiple Condition Formatting Rules, the only option is the AND. An OR option should also be available.

If you do a Excel export, it renders the headers value, which we set with an expression (customer specific localised text), but as CSV the header names/IDs are used.
It would be nice to have a 'Export Settings' category on the page properties, see attachment for example. Also shows another useful feature of disabling export option easily per report.

This is a feature request to allow a designer to set the locale at preview time.

We work on reports that are deployed and executed in many regions and locales around the world.

We cannot have our report designers switch the locale each time they need to test or validate a report, it would become too cumbersome.

Would you be able to add an option (default: Current locale) to the "Preview" screen in the designer that allows the report designer to set the locale to Preview the report as.

One of the main features the clients require when exporting the reports to XLS or XLSX is to have the page width already set to 1 page. But for none of these exporting options, this is possible, unless you intercept somehow the export functionality prior to rendering the document to the client

It would be nice to have 3D chart capabilities such as those found in the WPF ChartView or even the KendoUI charts.  The Telerik Reporting charts , although feature rich, are rather plain looking.
