Exempel

Följande kodexempel visar hur du använder egenskapen PropertyMap för att översätta egenskapen Margin för ett värdbaserat WPF-element. Mer information finns i Genomgång: Mappa egenskaper med hjälp av ElementHost-kontrollen.

// The AddMarginMapping method adds a new property mapping
// for the Margin property.
private void AddMarginMapping()

    elemHost.PropertyMap.Add(
        "Margin",
        new PropertyTranslator(OnMarginChange));
}

// The OnMarginChange method implements the mapping 
// from the Windows Forms Margin property to the
// Windows Presentation Foundation Margin property.
//
// The provided Padding value is used to construct 
// a Thickness value for the hosted element's Margin
// property.
private void OnMarginChange(object h, String propertyName, object value)
{
    ElementHost host = h as ElementHost;
    Padding p = (Padding)value;
    System.Windows.Controls.Button wpfButton =

Kommentarer

Windows Forms- och WPF-teknikerna har två liknande men olika egenskapsmodeller. Egenskapsmappning stöder samverkan mellan de två arkitekturerna. Mer information finns i Windows Forms and WPF Property Mapping.
