Nell'esempio di codice seguente vengono Button creati tre controlli in un form e ne viene impostata la dimensione e la posizione utilizzando le varie proprietà relative alla dimensione e alla posizione.The following code example creates three Button controls on a form and sets their size and location by using the various size-related and location-related properties. Per questo esempio è necessario disporre di Form un oggetto con larghezza e altezza pari ad almeno 300 pixel.This example requires that you have a Form that has a width and height of at least 300 pixels.

Commenti

I limiti del controllo includono gli elementi non client, ad esempio le barre di scorrimento, i bordi, le barre del titolo e i menu.The bounds of the control include the nonclient elements such as scroll bars, borders, title bars, and menus. Il SetBoundsCore metodo viene chiamato per impostare la Bounds proprietà.The SetBoundsCore method is called to set the Bounds property. La Bounds proprietà non viene sempre modificata tramite il set relativo metodo, pertanto è necessario SetBoundsCore eseguire l'override del metodo per assicurarsi che il codice Bounds venga eseguito quando la proprietà è impostata.The Bounds property is not always changed through its set method so you should override the SetBoundsCore method to ensure that your code is executed when the Bounds property is set.
