To edit an AJAX suggest text field you previously created, use the generated AJAX Suggest Text Field server behavior. Double-click its name in the Server Behaviors tab of the Application panel:
Select the recordset that stores the text suggestions.
Select the recordset column whose values will be used as text suggestions.
Select the text field in page that you are transforming into a suggest text field. If you leave the None option, a text field will be automatically generated. If you are editing a suggest text field, this drop-down menu is disabled.
Specify the maximum number of suggestions offered.
Note: With this server behavior you can edit an existing AJAX suggest text field in page or generate a new one (after previously creating a recordset).
