TextBox 类

定义

表示一个控件,该控件可用于显示或编辑无格式文本。Represents a control that can be used to display or edit unformatted text.

public ref class TextBox : System::Windows::Controls::Primitives::TextBoxBase, System::Windows::Markup::IAddChild

[System.Windows.Markup.ContentProperty("Text")]

示例

此示例演示如何使用 Text 属性设置 TextBox 控件的初始文本内容。This example shows how to use the Text property to set the initial text contents of a TextBox control.

备注

尽管该示例的 Extensible Application Markup Language (XAML) 版本可以使用<TextBox。文本 > 每个按钮的 textbox 内容的文本周围的标记, 但这并不是必需的, 因为 TextBox 应用 ContentPropertyAttribute特性的属性。Although the Extensible Application Markup Language (XAML) version of the example could use the <TextBox.Text> tags around the text of each button's TextBox content, it is not necessary because the TextBox applies the ContentPropertyAttribute attribute to the Text property.

<TextBox Name="tbSettingText">  
  Initial text contents of the TextBox.  
</TextBox>  
tbSettingText.Text = "Initial text contents of the TextBox.";  
tbSettingText.Text = "Initial text contents of the TextBox."  

有关其他示例, 请参阅本文档的4.0 版本:TextBox 类For additional examples, see the 4.0 version of this document: TextBox Class.

注解

控件在其Text属性中只能包含无格式文本。 TextBoxA TextBox control can contain only unformatted text in its Text property. 下图显示了一个TextBox示例。The following graphic shows an example of a TextBox.

TextBox 示例Example of a TextBox

TextBox是由多个封装的组件组成的复合控件。TextBox is a composite control that is composed of several encapsulated components. 因此, 某些事件不会向上冒泡到包含控件, 因为它们由封装的子元素处理。Consequently, some events do not bubble up to the containing control because they are handled by encapsulated child elements. 因此, 应用程序开发人员应侦听事件的隧道版本 (由前缀 "Preview" 表示)。Because of this, application developers should listen for the tunneling version of an event (denoted by the prefix "Preview").

TextBox仅支持未格式化文本。TextBox supports unformatted text only. 有关需要支持更丰富内容的应用程序, RichTextBox请参阅。For applications that require support for richer content, see RichTextBox. 对于需要接受密码或其他敏感输入的应用程序, 请PasswordBox参阅。For applications that need to accept passwords or other sensitive input, see PasswordBox.

TextBox使用和属性VerticalContentAlignment在中水平和垂直对齐文本。 HorizontalContentAlignmentHorizontally and vertically aligning text within a TextBox is done with the HorizontalContentAlignment and VerticalContentAlignment properties. 通过和属性VerticalAlignment在页面布局中对齐。 TextBox HorizontalAlignmentAligning the TextBox within the layout of the page is done with the HorizontalAlignment and VerticalAlignment properties.

隐藏周围TextBox边框的最佳方式是BorderThickness将的TextBox属性设置为0The best way to hide the border around a TextBox is to set the BorderThickness property of the TextBox to 0.

重要

TextBox为冒泡MouseUpMouseDown事件提供内置处理。TextBox has built-in handling for the bubbling MouseUp and MouseDown events. 因此, 不会调用在MouseUp TextBox中侦听或MouseDown事件的自定义事件处理程序。Consequently, custom event handlers that listen for MouseUp or MouseDown events from a TextBox will not be called. 如果需要响应这些事件, 请改为侦听隧道PreviewMouseUpPreviewMouseDown事件, 或使用HandledEventsToo参数注册处理程序 (此选项仅可通过代码使用)。If you need to respond to these events, listen for the tunneling PreviewMouseUp and PreviewMouseDown events instead, or register the handlers with the HandledEventsToo argument (this latter option is only available through code). 不要将事件标记为 "已处理", 除非你TextBox有意要禁用这些事件的本机处理, 并注意这会对控件的UIUI产生显著影响。Do not mark the event handled unless you deliberately want to disable TextBox native handling of these events, and be aware that this has notable effects on the control's UIUI.

默认TextBox情况下, 滚动条在上不可见。Scrollbars are not visible on a TextBox by default. 若要使滚动条可见, VerticalScrollBarVisibilityHorizontalScrollBarVisibility将和Visible属性Auto设置为或。To make scrollbars visible, set the VerticalScrollBarVisibility and HorizontalScrollBarVisibility properties to Visible or Auto.

通常, TextChanged事件应该用于TextBox在或RichTextBox更改中的文本时进行检测, 而不KeyDown是像预期那样进行检测。Usually the TextChanged event should be used to detect whenever the text in a TextBox or RichTextBox changes rather then KeyDown as you might expect. 请参阅如何:在示例中, 在文本框中的文本发生更改时进行检测。See How to: Detect When Text in a TextBox Has Changed for an example.

自定义 TextBox 控件Customizing the TextBox Control

若要对多个TextBox控件应用相同的属性设置, 请Style使用属性。To apply the same property settings to multiple TextBox controls, use the Style property. 您可以修改默认值ControlTemplate , 为控件指定独特的外观。You can modify the default ControlTemplate to give the control a unique appearance. 有关创建的ControlTemplate详细信息, 请参阅通过创建 system.windows.controls.controltemplate> 自定义现有控件的外观For more information about creating a ControlTemplate, see Customizing the Appearance of an Existing Control by Creating a ControlTemplate. 若要查看特定于的TextBox部分和状态, 请参阅TextBox 样式和模板To see the parts and states that are specific to the TextBox, see TextBox Styles and Templates.

此控件的依赖属性可能由控件的默认样式设置。Dependency properties for this control might be set by the control's default style. 如果按默认样式设置属性, 则当控件出现在应用程序中时, 属性可能会更改为默认值。If a property is set by a default style, the property might change from its default value when the control appears in the application. 默认样式取决于应用程序运行时使用的桌面主题。The default style is determined by which desktop theme is used when the application is running. 有关详细信息, 请参阅默认的 WPF 主题For more information, see Default WPF Themes.

备注

只有视觉对象属性已存在于控件的默认模板中并且已使用 TemplateBinding 设置时,设置该属性才有效。Setting a visual property only has an effect if that property is both present in the control's default template and is set by using a TemplateBinding. 通过创建 ControlTemplate 自定义现有控件的外观一文的更改控件的视觉结构部分可以找到视觉属性列表。You can find a list of visual properties in the Changing the Visual Structure of a Control section in the Customizing the Appearance of an Existing Control by Creating a ControlTemplate article.
