# How to: Set the Text Content of a TextBox Control

This example shows how to use the <xref:System.Windows.Controls.TextBox.Text%2A> property to set the initial text contents of a <xref:System.Windows.Controls.TextBox> control.

> [!NOTE]
> Although the [!INCLUDE[TLA#tla_xaml](../../../includes/tlasharptla-xaml-md.md)] version of the example could use the `<TextBox.Text>` tags around the text of each button's <xref:System.Windows.Controls.TextBox> content, it is not necessary because the <xref:System.Windows.Controls.TextBox> applies the <xref:System.Windows.Markup.ContentPropertyAttribute> attribute to the <xref:System.Windows.Controls.TextBox.Text%2A> property. For more information, see [XAML in WPF](../advanced/xaml-in-wpf.md).
