Implementing Custom User Functions

[Samuel]

Hi!

I'm not sure if this is the right place to post this. I'm trying to figure out how to implement custom user functions for use with the reporting server. I was successfully able to implement custom aggregate functions as per this documentation: https://docs.telerik.com/reporting/expressions-user-aggregate-functions

However, when attempting to implement custom functions using this documentation, I cannot get it to work: https://docs.telerik.com/reporting/expressions-user-functions

The functions implemented in this way show up for use in the standalone report designer, but when using them they return an error: "function not defined in current scope"

Am I missing something obvious? Any help would be appreciated! 

Thanks

Hello Samuel,

Generally, the Expressions are evaluated against data scopes. Do you pass arguments with your custom user function? Do you use data field values in the Expressions for these arguments? Are the fields valid in the scope of the Expression?

Feel free to send us a runnable sample report and the code of the function for local investigation.

The following KB may be useful when deploying the user functions in the Report Server - How to configure Telerik Report Server to use reports with custom functions.
