Property Value

Type: System.Web.UI.WebControls.TextBoxMode
One of the TextBoxMode enumeration values. The default value is SingleLine.

ExceptionCondition
ArgumentOutOfRangeException

The specified mode is not one of the TextBoxMode enumeration values.

Use the TextMode property to specify how a TextBox control is displayed. Three common options are single-line, multiline, or password text box.

When the TextBox control is in multiline mode, you can control the number of rows displayed by setting the Rows property. You can also specify whether the text should wrap by setting the Wrap property.

If the TextBox control is in password mode, all characters entered in the control are masked.

This property cannot be set by themes or style sheet themes. For more information, see ThemeableAttribute and ASP.NET Themes and Skins.

The following code example demonstrates how to use the TextMode property to specify a multiline text box.

Security noteSecurity Note

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.
