TextBoxBase.Multiline Property

Gets or sets a value indicating whether this is a multiline text box control.

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

abstract Multiline : bool with get, set
override Multiline : bool with get, set

Property Value

Type: System.Boolean
true if the control is a multiline text box control; otherwise, false. The default is false.

A multiline text box allows you to display more than one line of text in the control. If the WordWrap property is set to true, text entered into the multiline text box is wrapped to the next line in the control. If the WordWrap property is set to false, text entered into the multiline text box control will be displayed on the same line until a newline character is entered.

The following can be used as newline characters:

You can add scroll bars to a text box using the ScrollBars property to display horizontal and/or vertical scroll bars. This allows the user to scroll through the text that extends beyond the dimensions of the control.

NoteNote

Because the default value of the Multiline property is false, the default size of a TextBox will be in accordance with the font size even if you resize the TextBox. To get a consistent size for your TextBox, set its Multiline property to true.

NoteNote

On Japanese operating systems, if the Multiline property is set to true, setting the PasswordChar property will display the text of the password, thus compromising system security. Therefore, on Japanese operating systems, set the Multiline property to false if you set the PasswordChar property.

NoteNote

This property is set to false by default for all derived classes, with the exception of the RichTextBox control.

For a RichTextBox control, the RichTextBox.Multiline property affects whether or not the control will automatically resize, as follows:

The following code example uses TextBox, a derived class, to create a multiline TextBox control with vertical scroll bars. This example also uses the AcceptsTab, AcceptsReturn, and WordWrap properties to make the multiline text box control useful for creating text documents.
