Sequence Using

Use this option to select which of the table fields is to be the one used to determine the sequence of the entries in either the combo box or the list of radio buttons. 

If you choose the option "All key fields" this means that the table entries will be displayed in the order they arrive from the table data handler function.

If the table data handler function is the generic table data handler then the arrival sequence is sorted by the key fields.

This property is in the Code Table Visualization tab.
