Retrieving row JSON data

I want to be able to retrieve the data from a row when I double click on it. Currently it returns the rowId and the cellIndex. I could retrieve data by cell index but that is not a viable solution if the user has the options to re-order columns.

Is there a way to get the entire json string for a certain row? or maybe like a get cell value by providing column name and rowID?

thanks for your help

I was able to get this working by setting ids to the columns in the beginning and then just getting indexbyId. Still not as nice as being able to retrieve row JSON data by rowID but works for now
