Public ReadOnly Property PropertyMap As PropertyMap

Egenskapsvärde

En PropertyMap som mappar WindowsFormsHost egenskaper till egenskaper på den värdbaserade Windows Forms kontrollen.

Exempel

I följande kodexempel visas hur du lägger till en mappning för FlowDirection egenskapen till en WindowsFormsHost kontroll.

// 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

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.
