KBItem (subclass of KBObject)

Display expression (expr)

Expression for value to be displayed in the control. If empty, then the control is not set by the query.

Marked foreground colour (markfgcolor)

Forground colour when row is selected

Marked background colour (markbgcolor)

Read Only (rdonly)

Set this option to prevent update of the displayed value by the user. Note that the control can still be updated from a script.

Write Only (wronly)

This option is only useful for rekallWeb. If set then it is assumed that control values are never retrieved in a script. Mainly on rich-text controls that are only used for display.

No Update (noupdate)

If this option is set, the database is never updated from the control (even if the contents are changed). By default, the contents of no-update controls are not validated; set verified only to force verification without update.

Tab order (taborder)

Tab and shift-tab cycle through controls in increasing tab order. A tab order of zero means that the control cannot be entered by tabbing.

Default value (default)

Default value to use if field is not entered

Error Text (errtext)

Text used to customise various popups. Currently only used at block level by record insert/update/delete confirmation dialogs.

Validation flag (valflag)

Set this option to display a validation indicator to the left of the control, which shows whether the control contents are valid or not. Required shows only if the control could be invalid; reserve space uses up space oven if the validator is not show, to maintain alignment.
