The number of the row that you want placed in edit mode.
The field on the row to be edited.
If the Grid's 'RowEditStyle' is set to 'RowOnDemand', puts the specified row into edit mode.
Focus is set to the specified field (field must be uppercase, with spaces in the fieldname replaced with underbar). This method is equivalent to double clicking on a particular field in a Grid row to edit that field.
