Hi,
Currently working with Telerik reporting . how to Bind the MongoDB database collection to the Telerik Reporting ?
Thanks,

We use Web service data source in a report which has long OData query.
After adding filters, the OData query becomes too long. That's why it causes 404.15 error.
This is probably due to the limitation of maximum Url length in browsers. It is about 2048 characters (for IE). So there different limits for different browsers and web servers. https://www.geeksforgeeks.org/maximum-length-of-a-url-in-different-browsers/
To solve the issue probably we can use POST method in the web service data source instead of GET method.
I have "@url", "$select", "$expand" and "$filter" parameters set in the data source. How to use those parameters in body of the post request? And is it good solution?
As a sample report you can use attached report (TestProductReport.zip). The sample report has web service data source. The query in Service URL is short in this case, but we have long query in other report.
Getting error 400 when previewing the sample report. Any idea to fix this issue?
Following the instructions on the the web site and the video for building a ASP ,NET CORE 5 app to host Telerik reporting using VS 2022.
When I paste in the block:
services.TryAddSingleton<IReportServiceConfiguration>(sp =>
new ReportServiceConfiguration
{
ReportingEngineConfiguration = ConfigurationHelper.ResolveConfiguration(sp.GetService<IWebHostEnvironment>()),
HostAppId = "Net5RestServiceWithCors",
Storage = new FileStorage(),
ReportSourceResolver = new UriReportSourceResolver(
System.IO.Path.Combine(sp.GetService<IWebHostEnvironment>().ContentRootPath, "Reports"))
});
I get: The name ConfigurationHelper does not exist in the current context.
The suggested fixes do not seem right. What do I need to include in the project to use this?
I have Telerik report created from visual studio report designer (.net v4.0). Now i want to convert it to .trdp file where I'm going to reuse it in different project.
but i was unable to convert it using telerik report designer.
when i use open option next button and finish button is disabled in import report wizard.
when i try to use new report option it does not have proper option to select from .net class library dll.
does anyone have any idea how to convert .net class library report to .trdp?
Just installed reporting, in VS 2022 vb..net I add a new item Telerik Report R2 2022 (Blank) and the designer opens with the "To prevent possible data loss...' message.
Value cannot be null. Parameter name instance
How do I resolve this error?
Hello,
I have a report bound to a remote SQL Server, and when I try to run it from my developer machine I always get the same error:
I have tried to increase the timeout limit in the database connection but it made no difference.
Also, I am not being able to change connection strings from developer to production at runtime, wich could avoid this situation.
How should I proceed?

Hello,
I am trying to create a report with multi line text on a pre printed sheet of paper.
The problem is that I cannot set the line height of text and the result is not good (see the attached screenshot). If I increase the font to match the printed dot lines it looks enormous and still not good.
I tried the htmlTextBox but it does not seem to support style="line-height:1cm"
What are my options?
Hi
I have a license for Telerik Reporting.
I am the only developer and wish to add Reporting to another PC. Could you please tell me whether both Visual Studios will be able to produce licenced output for our hosted web service?
Many thanks,
Colin

Hello,
I have an issue on a project where a report printed from wpf report viewer is never printer for certain users.
My investigations so far :
- The same report is exported to pdf and printed on the same printer without issue (that's the current solution for users)
- The same report is printed without issue on my printer
The report gets sent to the printer queue but nothing comes out of the printer, so I ended up thinking about the document name in the printer queue generated by TelerikReporting. This Document Name is very long and I think this might be the issue for some printers, this document seems to be generated from the typename of the list of ReportParameters (see the attached picture). Is it possible to change this name to something shorter ? I tried using the DocumentName property in the ReportDesigner on my trdp file but it did not change the name in the printer queue.
Otherwise did anybody encountered this kind of issue with printing ?
Thanks

I have the following VB.Net class library as a dll, containing the function with a given namespace:
Imports Telerik.Reporting.Expressions
Public Class ReportExtensions
<[Function](Category:="Report Extended Functions", [Namespace]:="ReportExtensions", Description:="Returns a string that was given to the function")>
Public Function TestFunc(str As String) As String
Return str
End Function
End Class
Here is the location of the dll:

Here is a simple expression on a textbox on the Standalone Report Designer (also I cannot physically find my function declared in the editor window, I just have to type in the exact name):
The function should simply return "asd", but for some reason I see nothing when previewing the report. The textbox below works as expected.
What am I missing?
I've followed steps from Issue with User defined function in ReportViewer in Reporting | Telerik Forums and Preview report definition, which uses an external assembly with user-defined functions or CLR objects | Telerik Reporting, to no avail.
