Hello I would like to set a Numeric Up Down control to readonly and I don't want it to response on klicks on the arrows. Intercept Arrow Keys = true; The result is that the control looks like Read Only but the arrow buttons still work and can change the value. Thanks Ferdinand From the documentation for Up Down Base.

I set the Read Only property to false and the Intercept Arrow Keys to false too. Read Only: "true if the text can be changed by the use of the up or down buttons only; otherwise, false.

Bonjour, J'aimerai alerter l'utilisateur lorsqu'il effectue une mauvaise saisie dans un numeric Up Down (valeur pas dans les min/max ou saisie du style "12...0"). Net Component DT la propriété Text est cachée : "The Text has no affect on the appearance of the Numeric Up Down control; therefore, it is hidden in the designer and from Intelli Sense.".. Je laisse tombé, - Dans mon event Validating ".text" a déjà été modifié - J'ai créé un event Text Changed (qui est un event caché) mais il ne se déclenche pas - lorsque je fais un traitement dans le Keypress (simplement une assignation de dans une variable string), le numeric Up Down execute un autovalidate automatiquement et change donc le contenu du control pendant la saisie...

stupid behaviour for a property named Read Only, IMHO, but there you go). A read-only text box that the user can't modify is really just a Read Only Text Box with some useless buttons beside it.

Why, exactly, do you want those useless buttons there? One, a Numeric Up Down control; the other, a Text Box with Read Only set to true. When you want the user to be able to manipulate the value, Hide() the Text Box and Show() the Numeric Up Down control.

The only thing that comes to my mind is that you want a value that the user can change in some situations, but which is read-only in other situations. When you want it to be read-only, Show() the Text Box and Hide() the Numeric Up Down control.

You may freely use it to fill in the lack of an official numeric spinner on...
