Grab the dgData and loop through it.

put the dgData of group "MyGrid" into theDataA

repeat for each key theIndex in theDataA
  ... perform find on theDataA[theIndex]["firstName"], etc.
end repeat

Note that the above will not loop through the records in the order  
they appear but that may or may not matter to you. In the end you have  
the index (theIndex variable) that you can use in the Data Grid API.

If you want to loop through the records in order then follow the  
example in the lesson on exporting data.
