focus after alert

Iam using the grid v 1.5 and i have a validation in place for the third column that it doesnot allow numbers. so when an error occurs iam throwing an alert to the user. But once he clicks ok i want the fous to be back in same cell?? How can i do this?

In which moment alert shown? If you are using onEditCell event for it - you will need to switch the cell back to edit mode.
If you are using some custom DOM logic, and editor not closed yet - you can move focus by
