Hi

I am new to your reporting tool (coming from Crystal Report and trying to run away from it!).

I am trying to build a report that I will feed at runtime with a .Net dataset. How can I do it?

I saw https://docs.telerik.com/reporting/faq-xml-support but some links are not valid anymore.

I have also seen https://www.telerik.com/forums/using-telerik-report-designer-with-xml-datasource but it is 5 years old.

How does it work?

Hi

I am trying to add the converter for Crystal Reports in the stand alone designer. I have trier to follow the instructions from  https://www.telerik.com/support/kb/reporting/details/converting-reports-from-various-versions-of-crystalreports but can't get it to work.

I have edited both Telerik.ReportDesigner.x86.exe.config and Telerik.ReportDesigner.exe.config as shown here below but after the config is saved, the designer application just does not start. If I comment out the new sections, the designer app starts correctly. What am I doing incorrectly?

Hi There, 

We Telerik Reporting version to convert a data set in csv format and exporting it to PDF format.

There are around 41,000 rows in the csv file. And it generates around 1,000 pages in PDG format. 

controls used in the report are only csvDataSource, crosstab and textbox. No images used.

There are 2 groups, by store and then fiscal month. They are used for the bookmarks in PDF format report.

It takes much time generates the report and receiving System.OutOfMemoryException while exporting the report to PDF. 

But if I reduce the number of records in the source csv file, I'm able to export the data to PDF, so the code is working.

The requirement is to generate all data in one single PDF report as it's enterprise level report, filter/ report parameter is not an option in this case.

See attached screenshot of the error message.

Can anyone know this issue and give some suggestions?

 

Thanks a lot!

Susie

This question is two-fold:

First, I've found documentation where you can add an error handler to the Report.Error handler on individual reports, either in the constructor for the report or the usage of it. However, I'm hoping there might be a global way to add a handler to all reports so I can start logging errors during report rendering to ELMAH/etc. Are there any examples of this?

 

Second, once the errors are logged I would like to show a friendlier message on the report view rather than the error stack trace. I've seen am approach where the backend error handler throws an exception which fires the frontend viewer's errror handler to display some text, but could I just overwrite the stack trace info in the error object to a friendlier message in a single place to get that functionality for all reports?

I have been unable to get a Report Preview to work in Visual Studio (I am using 2017). The specific problem is that when I run the preview, I get the error "Could not load file or assembly '(my assembly), Version=(the version), Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified."

We require this custom assembly for various common lookups and data access, including accessing an S3  bucket using AWSSDK.S3.

Anyway, I have searched the web and these forums, and have tried dozens of solutions, none of which work. To prevent needless repletion of solutions that don't work, some solutions I have tried are on these links:

https://www.telerik.com/support/kb/reporting/details/how-to-use-external-assemblies-with-custom-user-functions-in-the-report-designer

https://www.telerik.com/forums/report-preview-fails-due-to-dependency

https://www.telerik.com/forums/designer-use-when-code-references-external-dlls

There are others, too but all basically the same thing. Either the solution tells me to add the runtime assemblyBinding and AssemblyReferences to the app.config, or to put the assemblies in the folder where the Report Designer executable is (i.e., "C:\Program Files (x86)\Progress\Telerik Reporting R2 2018\Report Designer"). That later is pretty dumb, as we would need to copy it there each time we rebuild the assembly, and I hope its not the actually solution... Regardless, I tried both of these solutions, and both together at the same time, and they simply do not work. I continue to get the error.

Most of the posts about this are from years ago, however, so perhaps things have simply changed, and those solutions do not work any more. I am sure we're not the only people trying to use telerik reports that call out to custom libraries.

So, the question is, how do we get the Report Preview to work in VS2017 when the report needs to access functions in an external, custom assembly?

Thanks in advance!

Since the null-coalescing operator (??) and the IsNull function appear to do the same thing, I was wondering if there is a performance benefit of using one over the other.

Hello, I have report parameter and I dynamically change the data source in available values, then I'd like to pick the first value (it could be various) as default. How can I implement this since the attribute ReportParameters["proc"].Value just accept an object?

Is the only option to query the data manually from code and then send first item?

Thank you for your attention!

We have a report created with several CSV data sources. In one CSV data source there are two rows by default, but in the we only need the first row only. We cannot change the CSV data source because it is generated by a separate application. Is selecting only first row only to appear in the report can be done by the designer is this feature does not yet supported by it. 

 

Thank you. 

Hi, I have a question! ¿What happened after the 30 days trial ends? ¿If I already compile a solution those controls keep working normally or they have a kind of error after that?

Hi All,

We have experienced some issues with Telerik reporting service tool and that the logs are given below.

{"message":"","exceptionMessage":"Client with ID '044210-0ccb' not found. Expired.","exceptionType":"Telerik.Reporting.Services.Engine.InvalidClientException","stackTrace":"   at Telerik.Reporting.Services.Engine.PersistableCollection`1.get_Item(String itemID)\r\n   at Telerik.Reporting.Services.Engine.ReportEngine.TouchClient(String clientID)\r\n   at Telerik.Reporting.Services.Engine.ReportEngine.CreateReportInstance(String clientID, String report, Dictionary`2 parameterValues)\r\n   at Telerik.Reporting.Services.WebApi.ReportsControllerBase.CreateInstance(String clientID, ClientReportSource reportSource)\r\n   at lambda_method(Closure , Object , Object[] )\r\n   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c__DisplayClass13.<GetExecutor>b__c(Object instance, Object[] methodParameters)\r\n   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.Execute(Object instance, Object[] arguments)\r\n   at System.Threading.Tasks.TaskHelpers.RunSynchronously[TResult](Func`1 func, CancellationToken cancellationToken)"}

Can you please check this as soon as possible and provide your inputs to get it resolved.
