Hi,

First of all I am posting this question because mostly all other questions related to the issue are kind of not uptodate.
I need to deliver reports those support both English/Arabic languages, which needs support for RTL direction,
to elaborate: if I have a table with three columns ProductID, ProductName, ProductPrice, I hope to get them in reverse order for Arabic language (ProductPrice, ProductName, ProductID)
would anybody please help me with this issue, is there a way to adjust the report layout to flow in RTL direction, I don't just need that for Table reports,
I also need it for Crosstab reports
I understand there is a limitation in RTL support, but would this be overcomed in the near future?

Thanks

Hi All,

I need to pass a session variable to a report.  If I could access the session variables from the report that would be good too.  Any ideas how to do that?

Thanks,

In a very few specific places in the product my company has built, we are using Telerik Reports in C#.

Report is trying to reach a stored procedure with 2 params: @languageCode and @invoicePaymentReceiptID

Creating a PDF Report however is giving me the below error:

ERROR

Value cannot be null.
Parameter name: type

STACK TRACE

   at System.Activator.CreateInstance(Type type, Boolean nonPublic)
   at System.Activator.CreateInstance(Type type)
   at Telerik.Reporting.Processing.TypeReportDocumentResolver.Resolve(IProcessingContext context, TypeReportSource rs)

DLL VERSION

Telerik.Reporting, Version=9.1.15.731, Culture=neutral, PublicKeyToken=a9d7983dfcc261be

CODE

 Telerik.Reporting.Processing.ReportProcessor reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();
 System.Collections.Hashtable deviceInfo = new System.Collections.Hashtable();
 Telerik.Reporting.TypeReportSource typeReportSource = new Telerik.Reporting.TypeReportSource();
 typeReportSource.TypeName = frmR.reportName;
 typeReportSource.Parameters.Add(new Telerik.Reporting.Parameter("languageCode", frmMain.language));
 typeReportSource.Parameters.Add(new Telerik.Reporting.Parameter("invoicePaymentReceiptID", 20421));
 //typeReportSource.Parameters.Add(new Telerik.Reporting.Parameter("reportID", tsbReportList.ComboBox.SelectedValue));
 Telerik.Reporting.Processing.RenderingResult result = reportProcessor.RenderReport("PDF", typeReportSource, deviceInfo);

 

It hits in the last line, trying to create the PDF report. 
Any ideas on the topic would be much appreciated.

Thank you.

 

Hi!

I'm not sure if this is the right place to post this. I'm trying to figure out how to implement custom user functions for use with the reporting server. I was successfully able to implement custom aggregate functions as per this documentation: https://docs.telerik.com/reporting/expressions-user-aggregate-functions

However, when attempting to implement custom functions using this documentation, I cannot get it to work: https://docs.telerik.com/reporting/expressions-user-functions

The functions implemented in this way show up for use in the standalone report designer, but when using them they return an error: "function not defined in current scope"

Am I missing something obvious? Any help would be appreciated! 

Thanks

     

Hello,

I am currently working on a project that requires me to generate a report then turn it into a pdf and send it in a email. I currently understand how to generate a report for a report viewer using uriReportSource, but I don't understand how to generate the report in the code behind then turn it into a pdf.

How to localize Rich Text Editor component displayed by the Send Mail Message Dialog in the HTML5 Telerik Report Viewer?

 

 

HI,

I want to share my experience with binding an IEnumerable<String> to a report.

Normally, you bind a collection of complex objects with public properties:

Then, in a report's textbox, you specify this expression to load the data from MyType object:



But what if you want to just bind a list of strings without creating redundant wrapper types?

You can't just set "= Fields" expression to a textbox, it will produce "Incorrect use of Fields" exception. But you can set following expression and it will work (RawData is of type Object, so I guess it calls ToString() method internally):

Hi all,

We are using Report Web Designer. We have implemented custom storage (IDefinitionStorage). We have implemented SaveDefinition method where it saves the edited report in a custom way.

There can be some validations and save can fail. For this I am just throwing a new Exception.  

The question is, which kind of exceptions needs to be thrown so that the message of exception shows in a report designer?

In an attachment you can see that the error message is showing in a general way, and it doesn't show my custom message.

 

Thanks,

Hello,

I'm trying to test Telerik Report with .NET Core 3.1 and object data source.

The report is working correctly when running from Visual Studio but when I publish and put it in IIS, I see the below error in every binding.
"An error has occurred while processing TextBox 'textBox15': The expression contains object 'OpeningBalanceDate' that is not defined in the current context"

I'm using the report designer and the assemblies that has the object datasource are netstandard2.0

What could be the issue?

I have Rest Service (ASP.Net Web Application-->Empty-->check MVC)

Result: successed (pictrure: 1.jpg)

I have project Angular and call Rest Service

<tr-viewer [containerStyle]="viewerContainerStyle"
[serviceUrl]="'http://localhost:56342/api/reports'"
[viewMode]="'INTERACTIVE'"
[scaleMode]="'SPECIFIC'"
[scale]="1.0">
</tr-viewer>

Error (picture: 2.jpg)

Error loading the report viewer's templates.
