Replied 3 August 2017, 3:21 pm EST
Thank you for the clarification but unfortunately I am still not able to replicate the issue at my end. I have attached a sample report and sample data. The report consists of several parameters, some of which have default values from a dataset created from the attached sample data. All the parameters have Allow Null property set, and hence the Null checkboxes in the report viewer are checked as soon as I preview the report.
Please have a look at the attached report and let me know if I missed something that would help me to replicate the issue at my end. I tested the issue with the latest version of Data Dynamics Reports i.e. v1.6.2260.3, I would suggest you to test the issue with the same. You can download it from the following link:
However, if you still face the same issue I would request you to modify the attached report to depict your issue so that I can replicate the issue at my end and debug it further.
