弹出窗口：页边距有问题

如何解决弹出窗口：页边距有问题

| 我正在开发Windows Phone应用。 我使用一个用户控件来显示一个弹出窗口：

<UserControl x:Class=\"XXXXXXX.Views.Lists.GameDescriptionControl\"
    xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"
    xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\"
    xmlns:d=\"http://schemas.microsoft.com/expression/blend/2008\"
    xmlns:mc=\"http://schemas.openxmlformats.org/markup-compatibility/2006\"
    mc:Ignorable=\"d\"
    FontFamily=\"{StaticResource PhoneFontFamilyNormal}\"
    FontSize=\"{StaticResource PhoneFontSizeNormal}\"
    Foreground=\"{StaticResource PhoneForegroundBrush}\" Height=\"290\" Width=\"460\">

    <Grid x:Name=\"LayoutRoot\" Background=\"{StaticResource PhoneChromeBrush}\" Margin=\"0,0\" Width=\"460\">
        <Grid.RowDefinitions>
            <RowDefinition Height=\"Auto\"/>
            <RowDefinition Height=\"133\"/>
            <RowDefinition Height=\"86\"/>
        </Grid.RowDefinitions>
        <TextBlock HorizontalAlignment=\"Center\" Margin=\"10\" Name=\"gameDescription\" Text=\"\" VerticalAlignment=\"Top\" TextWrapping=\"Wrap\" Grid.Row=\"1\" Style=\"{StaticResource PhoneTextTitle3Style}\" />
        <Button Content=\"{Binding Path=AppResources.Yes,Source={StaticResource LocalizedStrings}}\" Height=\"72\" HorizontalAlignment=\"Left\" Margin=\"50,5,0\" Name=\"okButton\" VerticalAlignment=\"Top\" Width=\"160\" Click=\"okButton_Click\" Grid.Row=\"2\" />
        <Button Content=\"{Binding Path=AppResources.No,Source={StaticResource LocalizedStrings}}\" Height=\"72\" HorizontalAlignment=\"Left\" Margin=\"244,0\" Name=\"cancelButton\" VerticalAlignment=\"Top\" Width=\"160\" Click=\"cancelButton_Click\" Grid.Row=\"2\" />
        <TextBlock Grid.Row=\"0\" x:Name=\"caption\" HorizontalAlignment=\"Left\" Margin=\"10\" TextWrapping=\"Wrap\" Text=\"{Binding Path=AppResources.Description,Source={StaticResource LocalizedStrings}}\" Style=\"{StaticResource PhoneTextLargeStyle}\"/>
    </Grid>
</UserControl>

这是显示弹出窗口的代码：

private void showInfo(int gameId)
{
    string gameDesc = getGameInfo(gameId);
    p = new Popup();
    GameDescriptionControl gd = new GameDescriptionControl();
    gd.Description = gameDesc;
    gd.OkClicked += new EventHandler(gd_OkClicked);
    gd.CancelClicked += new EventHandler(gd_CancelClicked);

    p.Child = gd;

    // Set where the popup will show up on the screen.
    p.VerticalOffset = 10;
    p.HorizontalOffset = 10;

    // Open the popup.
    p.IsOpen = true;
}

但是我得到这个： 如您所见，字幕TextBlock的页边空白不大。 有什么建议吗？     

解决方法

边距将指代文本块之外的区域。如果要将文本从文本块的边缘移开，则需要使用“填充”属性。     ,不像回形针这个词，但看起来您正在尝试创建自定义MessageBox。 检出此实施情况：http://cloudstore.blogspot.com/2011/01/customizing-messagebox-on-windows-phone.html。它是一个易于使用的消息框的出色实现，其外观/行为与真实的MessageBox十分接近，并且是轻量级的。 添加解决方案附带的几个文件，您要做的就是：

private MessageBoxService mbs = new MessageBoxService();

    ...

mbs.Closed +=new System.EventHandler(mbs_Closed);
mbs.Show(\"Confirm?\",\"Are you sure you wish to do that?\",MessageBoxServiceButton.YesNo,null);

void mbs_Closed(object sender,System.EventArgs e)
        {
            mbs.Closed -= mbs_Closed;

            if (mbs.Result == MessageBoxResult.Yes)
            {
...
            }
        }
