Hi Technical team,
I added a parameter in a report parent by following this link: https://docs.telerik.com/reporting/designing-reports-parameters-adding-parameters
I let all the values by defaults.
Then, I tried to pass the parameter to a SubReport under the parent report by following this link: https://docs.telerik.com/reporting/report-items-sub-report
All I did is in Report Designer.
However, after that the parent report is initiated, I found the value of parameters always null or empty.
Could you tell me where I did wrong?
