I haven't tried using DataGridXL with a file with that many records. There is a chance that the DOM node that is used for scroll-listening grows too large and browsers cannot handle that. I suspect that is where the error comes from.
However, I will add this to our list of issues, see where the error really comes from and where I can improve it (https://github.com/DataGridXL/DataGridXL2/issues/31). For now, I would say 10,000 records max to be sure.
