ElementHost.PropertyMap 属性

定义

命名空间:

System.Windows.Forms.Integration

程序集:

WindowsFormsIntegration.dll

获取属性映射，该映射确定控件上的ElementHost属性设置如何影响托管Windows Presentation Foundation (WPF) 元素。

public:
 property System::Windows::Forms::Integration::PropertyMap ^ PropertyMap { System::Windows::Forms::Integration::PropertyMap ^ get(); };

[System.ComponentModel.Browsable(false)]
public System.Windows.Forms.Integration.PropertyMap PropertyMap { get; }

[<System.ComponentModel.Browsable(false)>]
member this.PropertyMap : System.Windows.Forms.Integration.PropertyMap

Public ReadOnly Property PropertyMap As PropertyMap

属性值

PropertyMap

映射到ElementHost托管 WPF 元素上的属性的 APropertyMap。

属性

BrowsableAttribute

示例

下面的代码示例演示如何使用 PropertyMap 属性来转换 Margin 托管 WPF 元素的属性。 有关详细信息，请参阅 演练：使用 ElementHost 控件映射属性。

// 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 = 
        host.Child as System.Windows.Controls.Button;

    Thickness t = new Thickness(p.Left, p.Top, p.Right, p.Bottom );

    wpfButton.Margin = t;
}

' The AddMarginMapping method adds a new property mapping
' for the Margin property.
Private Sub AddMarginMapping()

    elemHost.PropertyMap.Add( _
        "Margin", _
        New PropertyTranslator(AddressOf OnMarginChange))

End Sub


' 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 Sub OnMarginChange( _
ByVal h As Object, _
ByVal propertyName As String, _
ByVal value As Object)

    Dim host As ElementHost = h
    Dim p As Padding = CType(value, Padding)
    Dim wpfButton As System.Windows.Controls.Button = host.Child


    Dim t As New Thickness(p.Left, p.Top, p.Right, p.Bottom)

    wpfButton.Margin = t

End Sub

注解

Windows 窗体和 WPF 技术具有两种相似但不同的属性模型。 属性映射 支持两种体系结构之间的互操作。 有关详细信息，请参阅 Windows 窗体和 WPF 属性映射。
