I export the same TRDP report that embeds a Bitmap image on Windows with GDI and on Linux Docker Container.
The result PDF file from the Linux environment is much bigger than the one generated on Windows.
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);
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);
}
I have overridden the SendMailMessage method of the ReportsController to implement the email-sending functionality of the web report viewers.
However, despite the method being implemented in my controller, inheriting from the ReportsControllerBase class, the method is never hit, and instead, I get a 501 Not Implemented response.
When rendering a report that displays an image through the PictureBox item with binary data in multiple threads within a Docker container, the following error is thrown:

My connection string contains spaces:

When I use the functionality 'Build new data connection', the designer throws the following exception:
If I create a report with a report parameter whose value is initially False, and then load it in the Native Angular Report Viewer, it is initially loaded properly.
However, if I click the "Preview" button, and the parameter is still unchecked(false), I get an error that the value is invalid.
The issue does not reproduce if the report parameter has AutoRefresh=True and there is no "Preview" button. I can successfully change the value of the parameter and the report loads without errors.

Currently, you can select multiple report items with the CTRL when you run the Web Report Designer on Mac, however, this is interpreted as a right-click. Please, check the attached video.
The correct behavior should be by using CMD.
Hi,
HTML viewer is showing Arabic words correctly while PDF Export shows splitted characters.
Correct word : فاتورة
Wrong word with splitted characters : ةروتاف
Please find attached screenshots for reference. The issue is appearing only with Linux container.
Telerik support ticket (https://www.telerik.com/account/support-center/view-ticket/1623687) was created and got reply that it is because of libgdiplus library and we were expecting that this issue will be resolved in R2 2023 but it still persists.
I have a report that uses custom assemblies and I export it through the ReportProcessor class in my .NET application.
For the reporting engine to resolve the custom assemblies, I had to pass an IConfiguration instance through its constructor where the custom assembly is referenced in the assemblyReferences element - Configuration for the ReportProcessor in .NET.
This approach does not work with the latest version of Telerik Reporting(18.2.24.924). I get errors that the assembly and the used types are not registered in the configuration file when I render the report.
According to the HTML5 Report Viewer documentation, the persistSession property of the viewer should be set to false by default.
This is not the case for the HTML5 WebForms Report Viewer, the value of its PersistSession property is true by default.
Since the HTML5 WebForms Report Viewer is a wrapper of the HTML5 Report Viewer, it should have the same default values.
Using the MySQL Connector/NET data provider with the latest version of Telerik Reporting - Telerik Reporting - Progress® Telerik® Reporting 2024 Q3 (18.2.24.924), leads to the following error when using Stored Procedures:

In my report, I show a tiny goat symbol with the font 'Segoe UI Emoji'. It looks good in the Standalone Designer for .NET Framework, but it is not shown in the PDF export from my .NET application, although the font is correctly embedded.
In the Standalone Report Designer for .NET 8, the goat is not displayed when previewing or exporting either.
