基本用法
长字串处理
LineBreak标籤在指定的地方手动换行。TextTrimming属性并设为**CharacterEllipsis**让TextBlock在没有足够空间的时候显示…。在没有足够空间显示这麽多文字时这是一种常见的方法。这也很适合用在当空间不足而且你不想使用多行的时候。你也可以使用**CharacterEllipsis**的另一种**WordEllipsis**当空间不足的时候以最后一个单字为单位显示就不会有单字只显示一部分的问题发生。TextWrapping 属性并设为**Wrap**让TextBlock在没有足够空间显示时自动换行。
TextBlock内联格式
粗体(Bold), 斜体(Italic), 下划线(Underline)
超连接 (Hyperlink)
Span块的使用
C# 或逻辑代码格式化文本
TextBlock tb new TextBlock();
tb.TextWrapping TextWrapping.Wrap;
tb.Margin new Thickness(10);
tb.Inlines.Add(An example on );
tb.Inlines.Add(new Run(the TextBlock control ) { FontWeight FontWeights.Bold });
tb.Inlines.Add(using );
tb.Inlines.Add(new Run(inline ) { FontStyle FontStyles.Italic });
tb.Inlines.Add(new Run(text formatting ) { Foreground Brushes.Blue });
tb.Inlines.Add(from );
tb.Inlines.Add(new Run(Code-Behind) { TextDecorations TextDecorations.Underline });
tb.Inlines.Add(.);
this.Content tb;
Label
Label和访问键(助记符)
StackPanel Margin10Label Content_Name: Target{Binding ElementNametxtName} /TextBox NametxtName /Label Content_Mail: Target{Binding ElementNametxtMail} /TextBox NametxtMail /
/StackPanel
使用控件作为Label的内容
Label Target{Binding ElementNametxtName}StackPanel OrientationHorizontalImage Sourcehttp://cdn1.iconfinder.com/data/icons/fatcow/16/bullet_green.png /AccessText Text_Name: //StackPanel
/Label
TextBox NametxtName /

/Label
TextBox NametxtMail /
Label控件和TextBlock控件的对比
那为什么要使用Label呢 好吧Label和TextBlock之间有一些重要的区别。 TextBlock仅允许您呈现文本字串而Label还允许您做下列的事情
设定边界(border)渲染其他控件例如一张图片通过ContentTemplate属性使用模板化的内容使用访问键聚焦到相关的控件上
最后一个点是使用Label取代TextBlock控件的其中一个主要原因.当你只是需要渲染简单的文本内容时,你应该使用TextBlock控件,因为它更轻量并且在大多数场景下性能比Label好.
TextBox
单行TextBox 多行文本框 有拼写检查的TextBox
SpellCheck类中名为IsEnabled的附加属性该属性仅支持对父控件进行拼写检查以及Language属性该属性指示拼写检查器使用的语言。
使用TextBox的选择属性
DockPanel Margin10TextBox SelectionChangedTextBox_SelectionChanged DockPanel.DockTop /TextBox NametxtStatus AcceptsReturnTrue TextWrappingWrap IsReadOnlyTrue /
/DockPanel
选择事件
private void TextBox_SelectionChanged(object sender, RoutedEventArgs e)
{TextBox textBox sender as TextBox;txtStatus.Text Selection starts at character # textBox.SelectionStart Environment.NewLine;txtStatus.Text Selection is textBox.SelectionLength character(s) long Environment.NewLine;txtStatus.Text Selected text: textBox.SelectedText ;
} 我们使用三个相关的属性来实现 SelectionStart它给出了当前光标位置或是否有选择它从什么位置开始。 SelectionLength它给出了当前选择的长度如果有的话。 否则它将返回0。 SelectedText如果有选择它会给我们当前选择的字符串。 否则返回一个空字符串。 Button

}private void BtnLoadFromResource_Click(object sender, RoutedEventArgs e)
{Uri resourceUri new Uri(/Images/white_bengal_tiger.jpg, UriKind.Relative);imgDynamic.Source new BitmapImage(resourceUri);
}
Stretch属性
Uniform: 这是默认模式。 图片将自动缩放以便它适合图片区域。 将保留图片的宽高比。UniformToFill: 图片将被缩放以便完全填充图片区域。 将保留图片的宽高比。Fill: 图片将缩放以适合图片控件的区域。 可能无法保留宽高比因为图片的高度和宽度是独立缩放的。None: 如果图片小于图片控件则不执行任何操作。 如果它比图片控件大则会裁剪图片以适合图片控件这意味着只有部分图片可见。

{InitializeComponent();cldSample.BlackoutDates.AddDatesInPast();cldSample.BlackoutDates.Add(new CalendarDateRange(DateTime.Today, DateTime.Today.AddDays(1)));
}
显示模式-显示月份或者年份 DisplayMode属性能够将Calendar 控件从一个你能选中一个日期的位置更改为到你能够选中一个月甚至一年的位置这是能通过DisplayMode 做到该属性默认为月份我们已经在之前的例子中都使用到了 ViewboxCalendar DisplayModeYear /

扩展控件
它的代码当然非常简单
Expander TextBlock TextWrappingWrap FontSize18 Here we can have text which can be hidden/shown using the built-in functionality of the Expander control. /TextBlock
/Expander
Expander 默认是不会扩展开来的所以就想第一张截图所看到那样。用户可以通过点击它扩展或者你能让它通过**IsExpanded** 属性初始时扩展
Expander IsExpandedTrue你当然也能在运行时读到这个属性如果你需要知道关于Expander 的当前状态。
