L’exemple de code suivant remplit la comboPaperSize zone de liste modifiable avec les formats de papier pris en charge par l’imprimante. En outre, un format de papier personnalisé est créé et ajouté à la zone de liste modifiable. est PaperName identifié comme la propriété qui fournit la chaîne d’affichage de l’élément ajouté via la DisplayMember propriété de la zone de liste déroulante.

// Add list of supported paper sizes found on the printer.
// The DisplayMember property is used to identify the property that will provide the display String*.
comboPaperSize->DisplayMember = "PaperName";
PaperSize^ pkSize;
for ( int i = 0; i < printDoc->PrinterSettings->PaperSizes->Count; i++ )
{
   pkSize = printDoc->PrinterSettings->PaperSizes[ i ];
   comboPaperSize->Items->Add( pkSize );
}

// Create a PaperSize and specify the custom paper size through the constructor and add to combobox.
PaperSize^ pkCustomSize1 = gcnew PaperSize( "First custom size",100,200 );
comboPaperSize->Items->Add( pkCustomSize1 );

// Add list of supported paper sizes found on the printer. 
// The DisplayMember property is used to identify the property that will provide the display string.
