Hi Jarrod,
Thank you for using Syncfusion products.
I am not able to reproduce the issue of StackOverFlowException in GridControl while scrolling. I have created a sample, could you please reproduce the issue in this sample, so that I could provide you the exact solution? Or please send us your sample with issue, we will analyze it and provide you the details.
Please refer the sample available in the link below and let me know if it helps:
