ComboBox DisplayValue

[michaelkatz]

I am using a dropdown combobox, style = 0.

I nedd to detect when the user enters something not in the list, (which is populated using the addlistitem method).

It appears that the displayvalue is not updating accurately.

For example: if the textbox portion contains 'hat' and the user keypresses an 'e', the displayvalue is not updated. It is still 'hat'. This is only happening for the first keystroke. after that it work fine.

The same thing happens if the user starts with an empty textbox portion.

Until the displayvalue is correct, the listindex is also inaccurate. I am finding it very difficult to test if the 'displayvalue' is in the list.

Help???

You could add the following code in lostfocus of the combo box:

LOCAL lnLoop, llFound
llFound = .F.
WITH THISFORM.COMBO1
FOR lnLoop = 1 TO .LISTCOUNT
IF .VALUE = .LIST(lnLoop)
llFound = .T.
ENDIF
ENDFOR
ENDWITH
IF .NOT. llFound
= MESSAGEBOX("Not Found!&quot
NODEFAULT
ENDIF

You didn't mention what method you were in when you checked the DisplayValue property. If it was in the InteractiveChange method, that's too soon in the event model to pickup the change. You need to check this in the valid method.

Both replies I received are helpful and informative. I was checking the value in the InterAciveChange method. They both seem to agree that the IC method is too soon to check.

I am still trying to figure out why everything works fine after the first keystroke. The IC method reports the correct value starting with the second keystroke.
