The default value of the report property SkipBlankPages is True and when there is an error in the report, for example, due to a problem with the connection to the database, the error message may be hidden as the report is not rendered at all.

The report should be rendered in order to display the error message also when SkipBlankPages is True.

I want each time a user logs out from my application its session in the Reporting REST Service also to expire. I tried to perform the Unregister Client request with a custom code. However, I need the clientId and there is no straightforward way to get its value from the viewer.

It turns out that the Reporting REST Service keeps its own client sessions that are different from the hosting application sessions. For that reason, the Telerik Reporting REST Service doesn't know whether a user is logged in/out in the main application. Therefore, a Logout functionality in the viewer will be beneficial for scenarios like the described one.

I would like to be able to access the report template layout using the ref so that I can save the report template outside of the designer.  Similar to this:

<button type="button"class="btn btn-light btn-sm" @onclick="Save">Save</button>
<WebReportDesigner @ref="designer1"
                   DesignerId="wrd1"
                   ServiceUrl="/api/reportdesigner"
                   Report="Dashboard.trdp"
                   ToolboxArea="new ToolboxAreaOptions() { Layout = ToolboxAreaLayout.Grid }"
                   PropertiesArea="new PropertiesAreaOptions() { Layout = PropertiesAreaLayout.Categorized }" />

@code {
    WebReportDesigner designer1;
 

    void Test()
    {
        var layout = (byte)designer1.Report.Layout;

    }
}
 

Coming from having developed many SSRS reports one thing I think telerik is missing is a nicer visualisation of row and column grouping in a table. SSRS does this really well as shown in the screenshot below where we can easily see which rows belong to the detail and 2 other groups.

I think this would be a very useful addition to the telerik designers!

I need to set a structured heading tags like <h2><h3> (https://www.w3.org/TR/WCAG20-TECHS/PDF9.html) so the pdf file can have those tags.

Please make the Reporting support more various tags so pdf files can have structured tags.

Generated PDFs do not have bookmarks in R2 2021 unless there is a TOC section in the report.

By setting the device info setting "ProcessItemActions", the generated PDFs have bookmarks again.

var reportProcessor = new Telerik.Reporting.Processing.ReportProcessor(); 
var reportSource = new Telerik.Reporting.UriReportSource();
reportSource.Uri = "some Uri";           
var deviceInfo = new System.Collections.Hashtable();
deviceInfo["ProcessItemActions"] = true;
reportProcessor.RenderReport("PDF", reportSource, deviceInfo);

When the PDF rendering extension has its "enableAccessibility" setting set to true, the text in the produced document cannot be selected using the Select Tool from the Adobe Acrobat Reader context menu. The text can be selected in other PDF readers like Foxit PDF Reader. The text is also selectable in Adobe Acrobat Reader when the document is created without enabling the accessibility features.

Hello

I have problem with visual studio auto close when I'm working in reporting designer.

When I'm working in reporting designer and do about 5 changes, Visual studio freezes and after few monents is restarted and I loose all my work.

It is really frequented problem and I can hardly work with reporting designer.

In Windows Event Viewer I everytime find this exception that referes to problem in GetAggregateFunctions().

Application: devenv.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

My need is to format numbers according to a custom culture with custom decimal, group symbols and number of decimal digits. For this I've created a custom CultureInfo object and set it up on Report.Culture property in a IReportSourceResolver implementation - I am using ASP.NET  from .net 5 example. For some reason, most of the NumberFormatInfo properties are ignored and a default, specific to the underlying culture code, is used. 

I need to programmatically change the NumberFormatInfo, because the service that is using Telerik Reporting is working in a multi tenant / multi culture environment and it must use the same report template but with different cultures for different requests.

Current result:

123 456 789
123 456 789,012
123 456 789 €
123 456 789,01 € 

Desired result, as per NumberFormatInfo settings (seen also in console):

123#456#789

123#456#789*01235

123##456##789 E

123##456##789**012346 E

Documentation reference:

https://docs.telerik.com/reporting/designing-reports-report-globalization

"A report is globalized with the help of a System.Globalization.CultureInfo object. You can specify a Culture for the entire Telerik.Reporting.Report by setting its Report.Culture property. This will force all Telerik.Reporting.TextBox items to respect the assigned Culture." 

But this does not appear to fully work. NumberFormatInfo of the Report.Culture property is not considered.

I've attached a project that reproduces this issues.

I am using Telerik Report Designer 15.1.21.512

I have created a Web Service Datasource:

The returned Raw String in Preview Data in the Wizard:

Everything appears to work, however the Datasource returns an Error:

When groupings in a cross tab or merged row table span multiple pages the actual row label should be carried over to new page along with a label of some sort (if desired) to mark group is being continued from previous page.

A possible solution would be to expose a ParametersAreaLoaded and ParametersAreaUpdated events with the needed arguments.

This will make migration from Silverlight easier. There the user has a direct access to them through the ReportViewerModel.
