自定义 WP7 弹出控件不显示内容

Question

我正在尝试为显示 EULA 的全屏弹出窗口创建用户控件。我无法显示我的内容，我不知道为什么。我已经创建了其他弹出控件，但我没有看到这些控件与这个控件之间有任何布局差异。

在 Expression Blend 中，我可以单击 LayoutRoot 节点，它会显示我的背景样式，但没有内容。如果我单击 popEula 节点，我会看到整个内容，包括背景样式。当我将控件添加到页面时，我只能看到背景。我不确定为什么我的所有内容都消失了。

<Grid x:Name="LayoutRoot" Style="{StaticResource MyBackgroundStyle}">
    <Popup x:Name="popEula">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="*"/>
            </Grid.RowDefinitions>

            <!--This section is empty. Place new content here Grid.Row="1"-->
            <Grid Grid.Row="1" x:Name="ContentGrid" Margin="24, 0, 24, 0">
                <Grid.RowDefinitions>
                    <RowDefinition Height="435" />
                    <RowDefinition Height="*"/>
                </Grid.RowDefinitions>
                <ScrollViewer x:Name="ScrollViewer">
                    <TextBlock x:Name="LicenseText" Style="{StaticResource MyTextNormalStyle}"
                Text="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vestibulum bibendum semper ante a vestibulum. Ut ultricies tellus sit amet sapien viverra tempus.

                </ScrollViewer>

                <toolkit:WrapPanel Grid.Row="2" Margin="0, 48, 0, 0">
                    <Button x:Name="btnAccept" Style="{StaticResource MyButtonStyle}" Content="Accept" Width="150"/>
                    <Button x:Name="btnDecline" Style="{StaticResource MyButtonStyle}" Content="Decline" Width="150" Margin="20, 0, 0, 0" />
                </toolkit:WrapPanel>

            </Grid>
        </Grid>
    </Popup>
</Grid>

我首先在弹出窗口上设置宽度和高度，并设置 IsOpen =“true”。看起来您的弹出窗口未打开或尺寸奇怪并且无法正确显示。
