Thank you for contacting Syncfusion support.
We have analyzed the reported issue “DataForm truncates decimal points of Decimal property” and unfortunately, we are unable to reproduce the issue, decimal value works fine from our side. We have attached a tested video and attached a simple sample for the same.
Please check the sample and let us know if you still facing the same issue? If not, please modify the sample based on your scenario and revert us with the more details. It will be helpful for us to check on it and provide you the solution at the earliest.
