【WP8】让TextBox文本支持滑动（Scroll）
通过修改样式让TextBox支持文本滑动
在Silverlight上，TextBox是有文本滚动的功能的，当TextBox的文本过长时，可以进行拖动的，TextBox使用 VerticalScrollBarVisibility 和 HorizontalScrollBarVisibility 来控制滚动条的显示
在Windows Phone上的TextBox 也拥有 VerticalScrollBarVisibility 和 HorizontalScrollBarVisibility 两个属性，但是当设置这两个属性Visible后，却发现TextBox上的文本滑动不了，下面对比Silverlight和WP上的TextBox样式
WP8上的TextBox样式如下：
<Style x:Key="TextBoxStyle1" TargetType="TextBox">
<Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilyNormal}"/>
<Setter Property="FontSize" Value="{StaticResource PhoneFontSizeMediumLarge}"/>
<Setter Property="Background" Value="{StaticResource PhoneTextBoxBrush}"/>

WP8的TextBox修改后的样式
测试后发现，WP8上的TextBox可以滑动了（但发现看不到ScrollBar）
控制TextBox显示文本的位置
有时候我们需要在代码中向TextBox的Text添加内容，比如表情，这时候TextBox不在编辑状态，我们添加文本后可以通过TextBox.SelectionStart去控制TextBox显示的位置，添加内容后TextBox.SelectionStart会被设置为0，如果需要显示文本的末尾，可以用 textBox.SelectionStart = textBox.Text.Length - 1;
