Valid Event

Applies To   See Also

Occurs before a control loses the focus.

Syntax

PROCEDURE Control.Valid
[LPARAMETERS nIndex]

Parameters

nIndex

Uniquely identifies a control if it is in a control array.

Remarks

If the Valid event returns true (.T.), the control loses focus. If the Valid event returns false (.F.), the control does not lose focus.

The Valid event can also return a numeric value. Returning a numeric value has one of three effects:

• If 0 is returned, the control does not lose focus.
  
  
• If a positive value is returned, the value specifies the number of controls the focus advances. For example, if the Valid event returns 1, the next control gets the focus.
  
  
• If a negative value is returned, the value specifies the number of controls the focus moves back. For example, if the Valid event returns –1, the previous control gets the focus.
