Namespace:  System.Windows.Controls

XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation

<object>
  String
</object>

Property Value

Type: System.String
A string containing the text contents of the text box. The default is an empty string ("").

Identifier field

TextProperty

Metadata properties set to true

BindsTwoWayByDefault, Journal

Getting this property returns a string copy of the contents of the text box. Setting this property replaces the contents of the text box with the specified string.

This property does not support animation.

When used in data-binding scenarios, this property uses the default update behavior of UpdateSourceTrigger.LostFocus.

This example shows how to use the Text property to set the initial text contents of a TextBox control.

Note    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. For more information, see XAML Overview (WPF).

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