Property Value

Type: System.String

The text entered in the HtmlTextArea control. The default value is String.Empty.

Use the Value property to programmatically control the text entered in the HtmlTextArea control. This property is commonly used to retrieve the text entered in the text box, but you can also use it to specify the text to display in the control. This is useful if you want to provide a default value or display a message in the HtmlTextArea control.

System_CAPS_cautionCaution

This control can be used to display user input, which might include malicious client script. Check any information that is sent from a client for executable script, SQL statements, or other code before displaying it in your application. ASP.NET provides an input request validation feature to block script and HTML in user input. Validation server controls are also provided to assess user input. For more information, see Validation Server Control Syntax.

The following code example demonstrates how to use the Value property to determine the contents of the HtmlTextArea control. The contents are then displayed in the Web page.
