c# - Windows Phone Toolkit CustomMessageBox 长内容滚动

Question

在我的项目（windows Phone 8 C#/XAML .NET 4.5 Application）中，我使用的是Windows Phone Toolkit。

在使用 CustomMessageBox 时，我在将 CustomMessageBox 用于长文本时遇到了问题。

这是一个例子：

 CustomMessageBox box = new CustomMessageBox();
 box.content = "some really some really some really some really some really some really some really some really some really some really some really some really some really some really long text";
 box.Show();

并且文本不是包装或可滚动的。所以我尝试将其添加到文本块中：

CustomMessageBox box = new CustomMessageBox();
TextBlock txtblck = "some really some really some really some really some really some really some really some really some really some really some really some really some really some really long text";
txtblck.TextWrapping = TextWrapping.Wrap;
box.content = txtblck;
box.Show();

所以最后，文本根据我的需要换行，但还有另一个问题。如何使其可滚动 - 例如，当您有很长的文本时 - 一些长通知或法律协议等等......

我应该怎么办？我尝试将文本块添加到 ScrollViewer，但它不起作用。我可以滚动一点，但它不会保持可滚动状态，当我停止尝试向下滚动时，它会返回到起始位置。

例子：

 ScrollViewer viewer = new ScrollViewer();

 TextBlock txtInfo = new TextBlock();
 txtInfo.Text = "some long text here.....";
 txtInfo.TextWrapping = TextWrapping.Wrap;

 viewer.Content = txtInfo;

 CustomMessageBox Box = new CustomMessageBox();
 Box.Content = viewer;
 Box.Show();

如何使长文本/内容可滚动？我应该使用其他解决方案吗？

您需要为高度定义一个固定值

ScrollViewer viewer = new ScrollViewer() { Height = 500 /* fixed Height */ };

TextBlock txtInfo = new TextBlock();
txtInfo.Text = @"some long text here.....";
txtInfo.TextWrapping = TextWrapping.Wrap;

viewer.Content = txtInfo;


CustomMessageBox Box = new CustomMessageBox();
Box.Content = viewer;
Box.Show();
