You can bind textbox in the grid double click event to either grid's double click event or form's method. The grid's RecordSource table.column is providing information about currently selected row.

See http://blogs.lessthandot.com/index.php/datamgmt/datadesign/grid-class-that-allows-sorting-by-clicki/ for some implementation details.
