Hello Telerik Reporting Community,

We have released a new version of Telerik Reporting today, 2024 Q1 (18.0.24.130). Please update your existing installation at your earliest convenience.

You can review the Legacy Installer Vulnerability - Telerik Reporting article to learn more details about why we are recommending customers to update.

To get the new version, take the following steps:

1. Go to Downloads | Your Account. 
2. Select Telerik Reporting.
3. Download the msi installer file, run it, and follow the steps to completion.

Notes

As the KB article explains, the issue pertained only to the old installer component, and not Telerik Reporting contained within the installation package. It does not affect any applications you’re using Telerik Reporting with.

If you have a rare situation where you cannot update the PC installed version, there are various ways to keep a project using an older version of reporting even though the PC has a newer version installed.

• NuGet Option: Update your projects to use the Telerik Reporting NuGet packages, instead of local DLLs (see https://docs.telerik.com/reporting/getting-started/installation/installation-approaches#using-nuget-packages).

• Copied Assemblies Option: Copy the older version’s DLLs to the project directory, then update the project references to use the copied assemblies (instead of the assemblies in C:/Program files (x86)/Progress/Telerik Reporting [older version]/)

We highly recommend you open a Technical Support Ticket if you have a complex situation and would like to ask questions before updating the PC’s installed version. You can open a Support Ticket here => https://prgress.co/DevToolsSupport.

I am currently using Telerik Reporting version 15.1.21.616 (R2 2021 SP1) in my ASP.NET application. I noticed that the report viewer only exports to the legacy Excel format (.XLS) and there is no option for Excel (.XLSX) in the export formats.

I have checked the Bin directory of my installation, and I do not see the Telerik.Reporting.XlsxRendering.dll assembly, which I understand is required for XLSX export.

Im getting the "single-row subquery returns more than one row" error when using a stored procedure  as a datasource.

This is the beginning of the procedure that I am calling from the report:

create or replace PROCEDURE get_idoc_report (
    pStart_Date IN DATE,
    pEnd_Date IN DATE,
    pPrepMethod IN VARCHAR2,
    pAnalyticalMethod IN VARCHAR2,
    pInstru IN VARCHAR2,
    pMatrix IN VARCHAR2,
    pPrepAnalyst IN VARCHAR2,
    pAnalyticalAnalyst IN VARCHAR2,
    pWO IN NUMBER,
    pWO_ID IN VARCHAR2,
    pAR IN VARCHAR2,
    p_cursor OUT SYS_REFCURSOR
)
IS 
BEGIN
    OPEN p_cursor FOR
        select distinct 
            to_char(sysdate, 'MM/DD/YYYY') as Current_Date,
            to_char(pStart_Date, 'MM/DD/YYYY') as WO_Start, ......

I have run the procedure in SQL Developer using a record to get data from the cursor, and it returns the expected number of data rows. I have used the same query as a Text select datasource query in Telerik and it worked. Any idea why I am getting the "single-row subquery returns more than one row" ? I am thinking Telerik Standalone is not able to access the rows returned from the sys_refcursor output. Any help is appreciated. I have attached the procedure text and a screenshot of the datasource setup.

Using Telerik Report Designer Version 17.1.23.606 and Oracle Database 19C.

i get this error https://nuget.telerik.com/v3/index.json.   Response status code does not indicate success: 401 (Unauthorized). 

I BOUGHT THE $699 TELERIK REPORTING VERSION and I don't have a way to see my token in my account to connect to the Telerik feed. My account still seems to be a trial account. I already used my user ID, my email address, and my apikay to connect, but I couldn't. Any suggestions would be welcome. Thanks in advance.

Hi Telerik Team,

I’m working with Telerik Report Designer and using a Web Service Data Source that is protected with two-step authentication. In my report, I have three report parameters: ClientId, Year, and Month. These parameters are passed to the API and are also used in three corresponding filters on the data source to dynamically fetch data for a crosstab.

From my understanding, when I click on the Preview button in the Report Designer:

1. The first API call is made to retrieve the schema of the web service (to understand the structure).

2. The second API call is made to fetch the actual data, using the parameter values I’ve provided.

Could you please confirm whether this is the expected behavior — i.e., that the Web Service Data Source initiates two separate API calls (one for schema, one for data), or it calls more than three times during preview?

I’m asking this to clarify internally, as I need to explain this behavior to my team.

Thank you in advance!

Best regards,

hi,

    I would like to ask, why does Telerik Report request the /info api multiple times? Can this info interface be requested in other ways to reduce the number of times?

thanks.

I have base configuration in appsettings.json (.Net 9 application)

    "telerikReporting": {
        "assemblyReferences": [
            {
                "name": "My.Assembly.Reports"
            }
        ],
        "extensions": [
            {
                "name": "PDF",
                "parameters": [
                    {
                        "name": "FontEmbedding",
                        "value": "Subset"
                    }
                ]
            }
        ]
    }

It works. But now I have multi layered configurations. There is appsettings.json and multiple other configuration files as customer1.json, customer2.json etc. Every customer has own settings and ovn assemly with reports. All is registered in program.cs in standard way. And it does not work. Seems that reportings have some hardcoded logic to read only from file named appsettings.json and whole configuration system of .Net is ignored.

It ends with errors:

An error has occurred while processing Report 'XXX':
 The type "XXX.TelerikReport.ObjectDataSources.XXX.Root" contained in assembly 
"XXX.TelerikReport.ObjectDataSources, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" cannot be loaded. 
To help improve the application's security, the reporting engine prevents loading types that are not essentially needed or listed as trusted by the user. If you 
consider particular types or assemblies as trusted include them in the corresponding TypeReferences or AssemblyReferences element of the 
'Telerik.Reporting' configuration section in the application's configuration file

Am I right? How can I split configs to multiple settings files? Can reporting work with configuration system as designed in .Net?

Our .NET 8 project references .NET Standard Telerik.Reporting.dll.

After upgrading to Telerik Reporting 19.0 we get compiler warnings because of conflicting references.

Apparently, Telerik.Reporting.dll references .NET 9 DLLs (for example "System.Text.Json 9.0.0") while our .NET 8 project obviously references .NET 8 DLLs ("System.Text.Json 8.0.0").

I'm surprised this is happening because I thought Telerik.Reporting as a .NET Standard DLL should be independent of these .NET versions?

Do we have to go back to Telerik Reporting 18 to avoid these conflicts?

We are on .NET 8 because it has LTS (long term support) by Microsoft.

Hi all,

I'm developing a report and I don't know how to layout it.

The data source is a JSON DataSource and his structure is the following :

public class School
{
	public string Name { get; set; }
	public List<Class> Classes { get; set; }
}

public class Class
{
	public string Name { get; set; }
	public List<Student> Students { get; set; }
	public List<Teacher> Teachers { get; set; }
}

public class Student
{
	public string FirstName { get; set; }
	public string LastName { get; set; }
}

public class Teacher
{
	public string FirstName { get; set; }
	public string LastName { get; set; }
	public string Role { get; set; }
}

The desired layout is illustrated on the join file DesiredLayout.png and the report definition is joined too (containing datasource).

As you can see in the report definition, I don't use Header section. Because my list of teachers, on the top right, cannot be in a Header section.

And my problem is when the list of students for one class take more than one page, the school name, the class name and the list of teachers don't repeat.

My second problem is for the numbering on the footer. I don't know how to make it correctly.
