TextBox.AcceptsReturn Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets or sets the value that determines whether the text box allows and displays the newline or return characters.

Namespace: System.Windows.Controls
Assembly: System.Windows (in System.Windows.dll)

Syntax

'Declaration
Public Property AcceptsReturn As Boolean

public bool AcceptsReturn { get; set; }

<TextBox AcceptsReturn="bool"/>

Property Value

Type: System.Boolean
true if the text box allows newline characters; otherwise, false. The default is false.

Remarks

Dependency property identifier field: AcceptsReturnProperty.

If you change the AcceptsReturn property to true, text might be displayed differently due to text containing newline characters.

You can enable multi-line text in a TextBox control by using the AcceptsReturn property. Use the HorizontalScrollBarVisibility or VerticalScrollBarVisibility property to enable the horizontal scrollbars or the vertical scrollbars.

Examples

The following code snippet shows how you can use the AcceptsReturn property in XAML and code to create a multi-line text box control with scrollbars.

<StackPanel>
    <TextBox Margin="20,20,0,0" Text="A text box that demonstrates TextWrapping, TextAlignment, MaxLength, and AcceptsReturn" Width="300" Height="50" TextWrapping="Wrap" TextAlignment="Center" MaxLength="500" AcceptsReturn="True" />
    <TextBox Margin="20,20,0,0" Text="A text box that demonstrates HorizontalScrollBarVisibility and VerticalScrollBarVisibility" Width="300" Height="50" AcceptsReturn="True" HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Visible" />
</StackPanel>

Public Sub New()
    MyBase.New()
    InitializeComponent()
    CreateControls()
End Sub

Private Sub CreateControls()

    'Create stack panel
    Dim MyStackPanel As StackPanel = New StackPanel

    'Create the first text box
    Dim MyTB1 As TextBox = New TextBox
    MyTB1.Width = 300
    MyTB1.Height = 50
    MyTB1.Text = "A text box that demonstrates TextWrapping, TextAlignment, MaxLength and AcceptsReturn"
    MyTB1.TextWrapping = TextWrapping.Wrap
    MyTB1.TextAlignment = TextAlignment.Center
    MyTB1.MaxLength = 500
    MyTB1.AcceptsReturn = True
    MyTB1.Margin = New Thickness(20, 20, 0, 0)

    'Create the second text box
    Dim MyTB2 As TextBox = New TextBox
    MyTB2.Margin = New Thickness(20, 20, 0, 0)
    MyTB2.Text = "A text box that demonstrates HorizontalScrollBarVisibility and VerticalScrollBarVisibility"
    MyTB2.Width = 300
    MyTB2.Height = 50
    MyTB2.AcceptsReturn = True
    MyTB2.HorizontalScrollBarVisibility = ScrollBarVisibility.Visible
    MyTB2.VerticalScrollBarVisibility = ScrollBarVisibility.Visible

    'Add the text boxes to the stack panel
    MyStackPanel.Children.Add(MyTB1)
    MyStackPanel.Children.Add(MyTB2)
    Me.Content = MyStackPanel
End Sub

public Page()
{
    InitializeComponent();
    CreateControls();
}

private void CreateControls()
{
    //Create stack panel
    StackPanel MyStackPanel = new StackPanel();

    //Create the first text box
    TextBox MyTB1 = new TextBox();
    MyTB1.Width = 300;
    MyTB1.Height = 50;
    MyTB1.Text = "A text box that demonstrates TextWrapping, TextAlignment, MaxLength and AcceptsReturn";
    MyTB1.TextWrapping = TextWrapping.Wrap;
    MyTB1.TextAlignment = TextAlignment.Center;
    MyTB1.MaxLength = 500;
    MyTB1.AcceptsReturn = true;
    MyTB1.Margin = new Thickness(20, 20, 0, 0);

    //Create the second text box
    TextBox MyTB2 = new TextBox();
    MyTB2.Margin = new Thickness(20, 20, 0, 0);
    MyTB2.Text = "A text box that demonstrates HorizontalScrollBarVisibility and VerticalScrollBarVisibility";
    MyTB2.Width = 300;
    MyTB2.Height = 50;
    MyTB2.AcceptsReturn = true;
    MyTB2.HorizontalScrollBarVisibility = ScrollBarVisibility.Visible;
    MyTB2.VerticalScrollBarVisibility = ScrollBarVisibility.Visible;

    //Add the text boxes to the stack panel
    MyStackPanel.Children.Add(MyTB1);
    MyStackPanel.Children.Add(MyTB2);
    this.Content = MyStackPanel;
}
