WindowsFormsHost.PropertyMap 属性

定义

命名空间:

System.Windows.Forms.Integration

程序集:

WindowsFormsIntegration.dll

获取属性映射，该属性映射决定了设置 WindowsFormsHost 元素的属性会对托管的 Windows 窗体控件产生何种影响。

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

public System.Windows.Forms.Integration.PropertyMap PropertyMap { get; }

member this.PropertyMap : System.Windows.Forms.Integration.PropertyMap

Public ReadOnly Property PropertyMap As PropertyMap

属性值

PropertyMap

将PropertyMap属性映射到WindowsFormsHost托管Windows 窗体控件上的属性。

示例

下面的代码示例演示如何将属性的 FlowDirection 映射添加到 WindowsFormsHost 控件。

// The ReplaceFlowDirectionMapping method replaces the  
// default mapping for the FlowDirection property.
private void ReplaceFlowDirectionMapping()
{
    wfHost.PropertyMap.Remove("FlowDirection");

    wfHost.PropertyMap.Add(
        "FlowDirection",
        new PropertyTranslator(OnFlowDirectionChange));
}

// The OnFlowDirectionChange method translates a 
// Windows Presentation Foundation FlowDirection value 
// to a Windows Forms RightToLeft value and assigns
// the result to the hosted control's RightToLeft property.
private void OnFlowDirectionChange(object h, String propertyName, object value)
{
    WindowsFormsHost host = h as WindowsFormsHost;
    System.Windows.FlowDirection fd = (System.Windows.FlowDirection)value;
    System.Windows.Forms.CheckBox cb = host.Child as System.Windows.Forms.CheckBox;

    cb.RightToLeft = (fd == System.Windows.FlowDirection.RightToLeft ) ? 
        RightToLeft.Yes : RightToLeft.No;
}

// The cb_CheckedChanged method handles the hosted control's
// CheckedChanged event. If the Checked property is true,
// the flow direction is set to RightToLeft, otherwise it is
// set to LeftToRight.
private void cb_CheckedChanged(object sender, EventArgs e)
{
    System.Windows.Forms.CheckBox cb = sender as System.Windows.Forms.CheckBox;

    wfHost.FlowDirection = ( cb.CheckState == CheckState.Checked ) ? 
            System.Windows.FlowDirection.RightToLeft : 
            System.Windows.FlowDirection.LeftToRight;
}

' The ReplaceFlowDirectionMapping method replaces the
' default mapping for the FlowDirection property.
Private Sub ReplaceFlowDirectionMapping()

    wfHost.PropertyMap.Remove("FlowDirection")

    wfHost.PropertyMap.Add( _
        "FlowDirection", _
        New PropertyTranslator(AddressOf OnFlowDirectionChange))
End Sub


' The OnFlowDirectionChange method translates a 
' Windows Presentation Foundation FlowDirection value 
' to a Windows Forms RightToLeft value and assigns
' the result to the hosted control's RightToLeft property.
Private Sub OnFlowDirectionChange( _
ByVal h As Object, _
ByVal propertyName As String, _
ByVal value As Object)

    Dim host As WindowsFormsHost = h

    Dim fd As System.Windows.FlowDirection = _
        CType(value, System.Windows.FlowDirection)

    Dim cb As System.Windows.Forms.CheckBox = host.Child

    cb.RightToLeft = IIf(fd = System.Windows.FlowDirection.RightToLeft, _
        RightToLeft.Yes, _
        RightToLeft.No)

End Sub


' The cb_CheckedChanged method handles the hosted control's
' CheckedChanged event. If the Checked property is true,
' the flow direction is set to RightToLeft, otherwise it is
' set to LeftToRight.
Private Sub cb_CheckedChanged( _
ByVal sender As Object, _
ByVal e As EventArgs)

    Dim cb As System.Windows.Forms.CheckBox = sender

    wfHost.FlowDirection = IIf(cb.CheckState = CheckState.Checked, _
    System.Windows.FlowDirection.RightToLeft, _
    System.Windows.FlowDirection.LeftToRight)

End Sub

注解

Windows 窗体和 WPF 技术有两种相似但不同的属性模型。 属性映射 支持两个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。
