We are using Telerik Report Viewer in our ASP.NET MVC application. I've read the documentation about localizing the report viewer (https://docs.telerik.com/reporting/html5-report-viewer-localization) and most of the texts are localized now, but there are some other that I can't change.

For example, in the search menu, result list, 'page xx' text.

Can you add this string resource in the resources file?

Prerequisites: .NET Core application that uses HTML5-based report viewer and REST service with Kestrel web server.

When the application is stopped from the command prompt with CTRL+C, it does not stop all the dotnet.exe child processes that are spawn by the application and hangs on "Application is shutting down..." indefinitely.

This behavior might be related with the issue https://github.com/aspnet/Hosting/issues/960 which states that CTRL+C is not forwarded to the child processes.
Perform a detailed examination to see if there is an option to close the processes internally when a shutdown procedure is initiated.

When a textbox had a value and after that the value was deleted, if you try to set a language for the report the following error message occurs: "textbox26.width cannot be parsed as a unit because it does not contain numeric values. 

When you set a value of the border width less than 0.5px, then it will be not shown in the HTML report viewer. For that reason consider allowing values which are at least 0.5 px.

When exporting a long report with ContinuousPaper = true in Word format, the output document has text cut.

Based on the limitation explained in the Pagination section in Design Considerations for Word Rendering article of our documentation, Word supports maximum page size of 22 inches wide and 22 inches high. If the page is higher than 22 inches, some data may not be displayed in Print Layout view. So, in Word, a long document couldn't be rendered.

At least, this property could be avoided when printed in Word format.

When a Panel is left docked to the detail section of a report and a table spills to another page, leaving empty space at the bottom (to indicate the table continues), the Panel height is less than the detail section height.

When a column is hidden through binding, a small gap appears to the border of the next column.

When a TextBox is deleted from a localized report, if a new TextBox is added, its localized value would be set to the localized value of the deleted TextBox.

After the report is translated we started to change the sequence of parameters. This works fine except the translated texts do not move with it. So parameters have the wrong text.

Hi,

 

There is an issue where the search window that opens from the Report Viewer tool bar does not allow for deleting text from the search string input box using backspace.

The keyboard command provider seems to have many other keys covered for the intended behavior, but backspace does not seem to be handled appropriately.

When in a table group GroupKeepTogether is set to True and PageBreak to After, the Table item may not render correctly in physical paging formats. In formats, without physical paging, the report is displayed correctly.

If during the report rendering stage, one or more of the required entities in the File storage were removed/deleted by third-party software, it will prevent the report from finishing the rendering and throws a NullRefereceException:

System.NullReferenceException: Object reference not set to an instance of an object.
   at Telerik.Reporting.Services.Engine.Document.AddClientToolTipsResource(IList toolTips)
   at Telerik.Reporting.Services.Engine.Document.FinishRendering(ReportRendererResult result)
   at Telerik.Reporting.Services.Engine.ReportEngine.RenderReportDocument(String pendingRenderingId)
   at Telerik.Reporting.Services.Engine.TaskQueue.WorkerThread.ProcessItems()
   at Telerik.Reporting.Services.Engine.TaskQueue.WorkerThread.ThreadProc()
   at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)

   at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
   at System.Threading.ThreadHelper.ThreadStart()]

When dynamically create a new tab which contains a report viewer, only the first report is rendered correctly. The subsequent tabs with report viewers are empty.

Hi Support Team,

 

There an issue  for exporting  report to PowerPoint when there is grouping in table and tables goes to next page, 

I got this error : "The given key was not present in the dictionary"

I've attached sample trdx file for your consideration.

 

Thanks,

Mozhgan Javadi

Using the following code for updating the ReportSource of the viewer:

ngOnInit() {
  this.setParameters();
}

setParameters(): void {
  this.reportViewer.setReportSource({
    report: 'SampleReport.trdp',
    parameters: {}
  });
}

comes up with the error 

Argument of type '{ report: string; }' is not assignable to parameter of type 'JSON'.
  Type '{ report: string; }' is missing the following properties from type 'JSON': parse, stringify, [Symbol.toStringTag]

Currently, the workaround is to cast the reportSource object as follows:

ngAfterViewInit() {
  this.setReportSource();
}
 
setReportSource(): void {
  let rs = {
    report: 'SampleRepport.trdp',
    parameters: {}
  } as unknown as JSON;
  this.viewer.setReportSource(rs);
}

When exporting a report with Crosstab which data source doesn't have any data, and the NoDataMessage property is not set, the report designer/viewer throws an error with message "Index was outside the bounds of the array”

When attempting to export a report in Excel 97-2003 format, an exception is thrown: 

"The type initializer for Telerik.Reporting.Excel 97.Workbook threw an exception. Object contains non-primitive or non-blittable data."

As HTML, PDF and OpenXML-based renderings are supported on Linux/macOS machines, please remove the old Excel 97-2003 format.

When trying to set the 'parametersAreaVisible' option in the Angular viewer the application breaks with an error in the browser console:

"Can't bind to 'parametersAreaVisible' since it isn't a known property of 'tr-viewer'."

I would like WPF viewer to behave like WinForms viewer and to keep the content of the rendered in XAML report in the page area in case of exceptions when exporting in other formats.
