Hi David,
Thank you for using Syncfusion Products.
We are not able to reproduce the issue. When MinValue is set binding works fine.
Please check the sample attached and let us if we are following the steps correctly. If not, could you please modify the sample and send it to us or provide us with more information , so that we can analyze more on this and provide the fix at the earliest.
Please let us know if you have any queries
Regards,
Ramalakshmi.
