ControlToSourceAssigns the control value to the source of a control link.
FileToPageAutomatically updates the controls of a page with:
  • the values of the bound items in the current record (loaded in memory) of the data file described in the data model editor. This operation is performed regardless of the state of the controls (grayed, inactive or invisible).
  • the values of the bound WLanguage variables. This operation is performed regardless of the state of the controls (grayed, inactive or invisible).
FileToScreenAutomatically updates the controls in a window or page with:
  • the values of the bound items in the current record (loaded in memory) of the data file described in the data model editor.
  • the values of the bound WLanguage variables.
This operation is performed regardless of the state of the controls (grayed, inactive or invisible).
PageFromSourceAutomatically updates the controls of a page with:
  • the values of the bound items in the current record (loaded in memory) of the HFSL data file described in the data model editor.
  • the values of the bound WLanguage variables.
This operation is performed regardless of the state of the controls (grayed, inactive or invisible).
PageToFileAutomatically updates:
  • the value of the items in a data file with the value of the controls in the page. The basic of the data file items linked to the fields in the window are automatically assigned with the values of the corresponding fields.
  • the value of the WLanguage variables with the value of the window controls. The WLanguage variables linked to the fields of the Page are automatically assigned with the values of the corresponding fields.
This operation is performed regardless of the state of the controls (grayed, inactive or invisible).
PageToSourceAutomatically updates:
  • the value of the items in a data file with the value of the controls in the page.
