I have a calculated field of type Decimal where I may dynamically return 0 in some of the rows of data.

If this happens with the first data row, it will not respect the selected data type and will instead infer that the type of data is an integer.

If I use this calculated field in an aggregate function such as Sum(), since the type of the first value will be integer, it will treat the other values as integers as well and the total sum will be incorrectly aggregated.

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.

In the Standalone Report Designer, collection editors, such as the ReportParameter Collection Editor, do not show the context menu when a property is right-clicked, and resetting property values through such windows is not possible.

The Properties window of the designer illustrates the expected behavior.

Currently, the desktop viewers don't allow adding custom headers to their requests to the service.
In HTML5-based web viewers, this is possible through the AjaxPrefilter event.

The Web Report Designer does not entirely comply with CSP standards, necessitating the use of the 'unsafe-eval' directive in our CSP policies to enable its functionality.

This directive poses significant security risks and undermines the purpose of implementing CSP in the first place. Please remove this requirement.

Currently, the Native Angular Report Viewer does not support NodeJS 22. It is restricted to v16-21 of NodeJS and I would have to downgrade to use it.

When I try to open the edit dialog for a report parameter from the Report Explorer in the .NET Standalone Report Designer, the dialog does not open.

The same appoach works as expected with the .NET Framework Standalone Report Designer.

As an alternative for the .NET Standalone Report Designer, the second approach from the ReportParameter Collection Editor at a Glance - Telerik Reporting article may be used.

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:

Message=Concurrent operations from multiple threads on this type are not supported.

My connection string contains spaces:

When I use the functionality 'Build new data connection', the designer throws the following exception:

If I update a StyleRule from the Report Explorer in SRD.NET, the property grid becomes empty afterward, and I have to de-select the rule by selecting another style rule, then select it again to edit another style.

When using the Standalone Report Designer for .NET, the PropertyName dropdown is empty when creating a new style rule with AttributeSelector.

The issue is not present with the Standalone Report Designer for .NET Framework.
