推荐答案

您可以使用以下..

修改结果
增加了一个电网结合了宽度/高度固定页面 ActualWidth的/的ActualHeight 来实现中心

Edit
Added a Grid which binds its Width/Height to the FixedPage ActualWidth/ActualHeight to achieve centering

<DocumentViewer>
    <FixedDocument>
        <PageContent>
            <FixedPage HorizontalAlignment="Center">
                <Grid Width="{Binding RelativeSource={RelativeSource AncestorType={x:Type FixedPage}},
                                      Path=ActualWidth}"
                      Height="{Binding RelativeSource={RelativeSource AncestorType={x:Type FixedPage}},
                                       Path=ActualHeight}">
                    <local:MyUserControl HorizontalAlignment="Center"/>
                </Grid>
            </FixedPage>
        </PageContent>
    </FixedDocument>
</DocumentViewer>



不幸的是,Visual Studio 2010的设计师在这里打破,你会得到一个消息,说财产的页面'不支持类型的值'PageContent`结果
该报告如下:的

作为一种变通方法,你可以加载它背后

As a workaround you can load it in code behind

的XAML

<DocumentViewer>
    <FixedDocument Loaded="FixedDocument_Loaded"/>
</DocumentViewer>

后面的代码

private void FixedDocument_Loaded(object sender, RoutedEventArgs e)
{
    FixedDocument fixedDocument = sender as FixedDocument;

    MyUserControl myUserControl = new MyUserControl();
    myUserControl.HorizontalAlignment = HorizontalAlignment.Center;
    myUserControl.VerticalAlignment = VerticalAlignment.Center;

    Grid grid = new Grid();
    grid.Children.Add(myUserControl);

    FixedPage fixedPage = new FixedPage();
    fixedPage.Children.Add(grid);

    Binding widthBinding = new Binding("ActualWidth");
    widthBinding.Source = fixedPage;
    Binding heightBinding = new Binding("ActualHeight");
    heightBinding.Source = fixedPage;
    grid.SetBinding(Grid.WidthProperty, widthBinding);
    grid.SetBinding(Grid.HeightProperty, heightBinding);

    PageContent pageContent = new PageContent();
    (pageContent as IAddChild).AddChild(fixedPage);

    fixedDocument.Pages.Add(pageContent);
}
