Thank you for contacting Telerik support.
To automatically move to the next cell when a specific condition is met, you can subscribe to the ValueChanged
event of RadGridView and add your own logic. You can find a sample implementation in the attached project. Feel free to refer to it or edit it and do not hesitate to write again if you have any additional questions.
I hope this information helps.
