TextBox.Wrap Property

  • Reference

Definition

Namespace:
System.Web.UI.WebControls
Assembly:
System.Web.dll

Gets or sets a value indicating whether the text content wraps within a multiline text box.

public:
 virtual property bool Wrap { bool get(); void set(bool value); };
public virtual bool Wrap { get; set; }
member this.Wrap : bool with get, set
Public Overridable Property Wrap As Boolean

Property Value

Boolean

true if the text content wraps within a multiline text box; otherwise, false. The default is true.

Examples

The following code example demonstrates how to use the Wrap property to wrap text entered in the TextBox control.

Important

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.

Note

This property is applicable only when the TextMode property is set to TextBoxMode.MultiLine.
