This is a general question.
I was using the old version Syncfusion Report Designer 220.127.116.11 for a long time, and have some RDL files created by this tool.
While I installed the Bold Embedded Reporting Tools v2.1.23, by using the add-on Bold Report Designer to open my existing RDL files that were created by Synfusion Report Designer before, just as I mentioned. It failed to preview the template, showing some errors about row groups evaluating issues. But these RDL files can be previewed with the old version Syncfusion Report Designer without any issues.
So , here I just want to make sure, is Bold Report Designer fully back compatible with the old version Syncfusion Report Designer?
