Report Designer is crashing when defining a User Function (VS2017)

[NerdBrick]

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.
Exception Info: System.ArgumentNullException

Hi NerdBrick,

This seems to be a known issue with Report Designer in Visual Studio 2017, opening Edit expression dialog causes VS 2017 to crash.

The issue has already been fixed. You can download our latest internal build that includes the fix from your Telerik account -> Downloads -> Reporting.
With this build, Edit expression dialog with user function can be opened without issues on our side in VS 2017.

Thank you for the quick response.

Nope the Error already exists. Become the Error when editing a field in Report Designer 2019 SP1.

Hi Claus,

I tested with version 13.1.19.222 (from R1 2019 SP1) and opening the Edit Expression dialog works as expected on my side finding the user function correctly. Please check this video that I demonstrate it: https://www.screencast.com/t/5sEvdC0Toq. It is a silent video that could be opened in a browser with Flash plug-in installed.

Could you please test running the Upgrade Wizard to make sure that the project is upgraded correctly? Also, please make sure that the proper version of the .NET framework is used - check Reporting System Requirements.

Best Regards,
Silviya
