I am not sure about your requirement / "performing an action on edited row". I guess you want to save the edited state even after postback (the issue is not happening for me ;) ). If so you can try same approach described for persisting selection on rebind: You need to save the keyvalue of edited rows in ItemCommand event and put it in editmode from code in PreRender according to the keyvalues saved.
Could you provide some more information about the scenario that you are trying, if this does not help?
I've made a short screen capture to show you the scenario :
=> Two rows in edit mode and modified, one updated
=> The first row is not persisted ( because all rows are rebinded systematically, even if they was already populated )
In this case, you can persist the entered data for all records, thus ensuring that no data is lost. This can be done by updating all records, when a postback is made. Additional information on this option is available in the following topic:
