This appears to be a new problem with VS2017 (15.0.0+ 26228.10) and Reporting R1 2017

We have a large project that has worked well with VS2015, but after migration to VS2017 we are seeing the designer crash when we try to open a Value editor (Edit Expression) when the project has a User Function defined. 

I tried to add this one user function to the Sample report project downloaded from Telerik (CSharp.ReportLibrary)

public static class OurCompanyFunctions
    {
        [Function(Category = "Testing", Namespace = "OurCompanyNameSpace", Description = "What will happen?", IsVisible = true, Name = "FunctionName")]
        public static string ValueIsNull(object val)
        {
            return "did it work?";
        }
    }

I tried to change the "Value" on a Text box by opening the Edit Expression editor. 

Here is the Exception in the event log

Application: devenv.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

We are using Telerik Viewer in Winform. 

Is it possible to change the default layout view from 100% to Whole Page? When we generate the report, we want this option to be selected automatically. 

Hi all,

Is it possible to pass object with set of fields to sub report. I was going to load all data in main report and pass some parts to subreport but there are only simple types for parameters and no object type. is it possible via report designer or I have to convert to visual studio? report is quite complex

thanks in advance

I have a report/Invoice that was made using the Report Designer, so it's in trdp format.  It is server up via a MVC vb.net RESTful reporting service.  Despite countless setbacks due to the Telerik Report dynamic limitations, I actually have it working, but there it one final nail that needs to be pounded into the coffin...the Invoice Logo.  It, much like every things else in our system, is not static.  It needs to be set, to correspond to what company happens to be running the Invoice with that particular request.

The million dollar question, how does one dynamically set a picturebox in a trdp report via a call to a RESTful reporting service?  

I have a sinking feeling this is going to involve the ReportPackager. The Reports Controller is very simple:

Our main project is a Asp.NET core 2.0 MVC project that targets .NET Core 2.0. We would like to add Telerik reporting to our project. 

Unfortunately I cannot do that directly since the Telerik report engine is using GDI+ and therefore the project must target classic .net. This means I must do this in a separate project so I can not re-use services like authentication on the controllers etc. Second and more important, our project must run on linux which the reporting service can not. Also we would like to dynamically render the report viewer pages and not be depended on static html pages like the Html 5 report viewer. Because of this limitations Telerik reporting is now not an option for us.

So my questions is will Telerik reporting get full .net core support in the future so we can target .net core too? 

Best Regards,

Michel

Hi

Thank you

I would like to create a subgroup with a clustered graph. The first group will be the columns headers and the second one, the description in my first column.

The axis will be represented this way :

X - 2 groups

Y - The corresponding value between the 2 groups

I am using Telerik 2016.

English is not my first language, but I think that the image in attached files sums what I am trying to do.

Thanks in advance!

Hello,

I want to create a website project with asp.net.

And now I want to implement a ReportViewer in my project.

But when I drag and drop a reportviewer from the toolbox to the

MainContent of a masterpage, i get an error shown in the attached screenshot.

I can ignore this error and click OK, but when I want to set a ReportSource

there comes another warning.

Perhaps it is related to each other.

Is it not possible to drop a reportviewer to a MainContent of a masterpage?
