How to: Set the Text Content of a TextBox Control

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 in WPF.

Use the Text property to set the text contents

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

Set the Text Content of a TextBox Control
