The ReportsControllerBase is returning a JSON payload of { "InstanceId": "xxxx" } instead of { "instanceId": "xxxx" } that the Html5 ReportViewer is expecting. I believe the CreateInstance method should be using CreateJsonResponse instead of CreateResponse. I overrode the ReportsControllerBase.CreateInstance like the following to get it working again:

response = base.CreateInstance(clientId, reportSource);

// This is to work around a bug in telerik reporting.
BusinessLogicResponse v = BusinessLogicResponse.CreateInstance(HttpStatusCode.Created, ((ObjectResult)response).Value);
response = base.CreateJsonResponse(v);

Hi, in the wpf report viewer, the date picker in the parameter's zone don't have a "Today's date button". The standalone report designer have the "Today's date button".

Date picker of the report designer :

Date picker of the wpf report viewer :

Is it possible please to add the "Today's date button" for date pickers in the wpf report viewer?

Thanks a lot!

Even though I set "parametersAreaVisible" to false, the parameter area is still visible. A bit of tweaking.

Let me make a change request in the telerikReportViewer-18.3.24.1112.js file:

function showParametersAreaIfNecessary(params) {
            parametersAreaNecessary = hasVisibleParameters(params) || !controller.isReportAutoRun();
            showParametersArea(parametersAreaVisible && parametersAreaNecessary);
        }

If you have the latest Telerik.Reporting NuGet package (18.3.24.1112) installed simultaneously with the Telerik.Documents.Fixed NuGet package, indeed, the compile time error occurs:

The type 'Size' exists in both 'Telerik.Documents.Core, Version=2024.4.1106.20, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' and 'Telerik.Reporting, Version=18.3.24.1112, Culture=neutral, PublicKeyToken=a9d7983dfcc261be'

This undesired behavior is not reproducible with the previous version of Telerik Reporting. This is caused due to the fact that Telerik.Documents.Primitives.Size is contained in both assemblies/packages.

pls hlep, thanks.

I am displaying SVG images using a PictureBox, but all the SVGs appear in the same color rather than their original colors when viewing the report through the HTML5-based Report Viewers in the browser.

To verify, I checked the report directly in Telerik Report Designer, where the colors display correctly.

When exporting the report as a PDF from the same report viewer, the SVG images retain their original colors in the exported PDF.

My SVG images have embedded style classes. Some of the class names are the same although the styles may differ.

Currently(version 18.2.24.924), it is not possible to use bindings or conditional formatting on the styling of the radial gauge ranges.

I need to be able to change their styles, such as the color, based on my data.

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
  }
}

We have successfully downloaded and installed Google Open Sans fonts (from the URL:  https://fonts.google.com/specimen/Open%20Sans#:~:text=Open%20Sans%20is%20a%20humanist%20sans%20serif) to a Linux Ubuntu-based Docker container using the following Dockerfile script to install the dependencies and the fonts:

RUN apt-get update && apt-get install -y libfreetype6 libfontconfig1 fontconfig unzip

#Google Fonts
RUN mkdir -p /usr/share/fonts/truetype/googlefonts && cd /usr/share/fonts/truetype/googlefonts
COPY ["Open_Sans.zip", "/usr/share/fonts/truetype/googlefonts"]
RUN unzip -d /usr/share/fonts/truetype/googlefonts /usr/share/fonts/truetype/googlefonts/Open_Sans.zip
RUN rm -f Open_Sans.zip
RUN ls -al /usr/share/fonts/truetype/googlefonts
RUN fc-cache -fv
RUN fc-match OpenSans

Open_Sans.zip file should be in the solution folder when running the Docker from Visual Studio.

The fonts are displayed as expected when previewing in the browser. When exporting to PDF though, the Reporting engine throws the following exception when Open Sans font is used:

The same report with the same fonts is rendered successfully on Windows with the Standalone Report Designer for .NET 8 with both GDI and Skia graphics engines.

We faced the following issue when previewing a big enough report. Here are the steps to reproduce the bug:

1) after the report gets loaded, press the Preview button from the Parameters area.

2) as soon as the report starts loading, the class="trv-loading" is added to the Parameters area. While still report loading is in progress, press the "Stop Rendering" button.

3) When the message Report processing was canceled. is displayed, the Parameters area remains inactive. This happens because its class="trv-loading" is not removed as it is expected.

Currently, when you design a report with SqlDataSource, ObjectDataSource, etc. you need to have access to the corresponding database, assemblies, etc. to see the fields and use the drag-and-drop functionality of the report designers.

The requirement is to embed the corresponding schema in the report or designer to let the report creator access the data source fields even without these external resources.

As an example, in the WebServiceDataSource the report creator may use inline JSON rather than connecting to the Web Service. This saves time and resources required for establishing the connection that is in fact not necessary for design purposes.

When the report rendering is manually stopped through the Report Viewer, the Release Document request is made, however, it does not wait for the report rendering to be fully canceled, instead, it only sets a flag that it should stop.

The report engine checks for the flag periodically and eventually stops the report rendering, throwing an OperationCanceledException. I need to be able to catch this exception so that I can dispose of the document resources as soon as possible.

When there is rotated text (270 degrees) in the Crosstab header, the FreezeColumnHeaders and FreezeRowHeaders don't work as expected.

Resetting the angle to the default (0 degrees) fixes the problem.

Currently, to customize the report engine, for example to add some custom user functions, we have to either use the app config or provide a IConfiguration to ReportProcessor constructor, which seems to set a static field for all reports, and on top of that we have to provide a whole assembly (which will load ALL non-private static methods, I did try to use typereferences instead of assemblyReferences, but that doesn't seem to work for custom functions).

Meanwhile all we needed was to expose a handful of functions. Our current workaround is to have a whole assembly dedicated to that.

It'd good to be able to:

- Specify either a single class or individual methods through the library API (e.g. reportProcessor.AddCustomFunction("name", (arg) => ...); or reportProcessor.AddCustomFunctions(typeof(MyCustomFunctions);)
- Avoid using static state (it limits how the library can be used and, more importantly, tested)
- Maybe have a way to provide a Service Provider, that Telerik library would use to create services/classes and pull IConfiguration from, especially those we provide, that way the custom functions could use services from our application, rather than using all static methods.

Thank you,

When I render a report with Gujarati language text to PDF on Windows, the GDI graphics engine is used and the text is displayed properly.

When I render the same report with the Skia graphics engine, on Windows or Linux, the characters are misplaced or incorrectly drawn.

Hi Team,

I see you have written this custom example for using EntityFrameworkCore and SQL to act as a source of report storage (not cache storage).

This is a request to do the same but using the Azure Storage File Shares client library for .NET - Azure for .NET Developers | Microsoft Learn SDK to host the TRDP files.

For example:

ReportSourceResolver = new AzureStorageReportSourceResolver()

Thank you,

Mike

When the end-user closes the browser or the window where the web report viewer is rendering the report, the report rendering is not automatically cancelled on the server.

The report rendering should stop when the browser/window is closed.
