Hello Angie.

What are the UpdateValue and RefreshValue methods? Are they your own subclasses?

They are custom methods of my date textbox ( a textbox subclass ). I am sorry if I did not make that clear in my message.

If so, how should I implement them?

As I think I pointed out in my previous message,

Then I added a method called UpdateControlSource that is called from the control's Valid and UpdateValue that is called from its Refresh. Code like this in RefreshValue():

LOCAL ltValue

IF NOT EMPTY( This.cControlSource )
  ltValue = EVALUATE( This.cControlSource )

  *** Update the control's value from its cControlSource
  IF EMPTY( NVL( ltValue, {/:} ) )
   This.Value = {}
  ELSE
    IF VARTYPE( ltValue ) = 'T'
     This.Value = TTOD( ltValue )
    ELSE
      This.Value = ltValue
    ENDIF
  ENDIF
ELSE
  This.Value = {}
ENDIF

Obviously, the code the the UpdateControlSource method is the inverse of the method code I posted above. It must update the contents of the field referenced by the control's cControlSource property from its value.

Does that make it more clear?
