HtmlTextArea.Name Property

Gets or sets the unique identifier name for the HtmlTextArea control.

Namespace: System.Web.UI.HtmlControls
Assembly: System.Web (in system.web.dll)

public virtual string Name { get; set; }
/** @property */
public String get_Name ()

/** @property */
public void set_Name (String value)

public function get Name () : String

public function set Name (value : String)

Not applicable.

Property Value

A string that represents the value of the Control.UniqueID property.

Use the Name property to determine the unique identifier name for the HtmlTextArea control. In this implementation of the property, the get accessor returns the value of the Control.UniqueID property. However, the set accessor does not assign a value to this property.

NoteNote:

The set accessor does not assign a value to this property because the Name property must have the same value as the Control.UniqueID property for the HtmlTextArea control to work properly.

Classes that inherit from the HtmlTextArea class may override this implementation, if necessary.

The following code example demonstrates how to use the Name property to select an HtmlTextArea control on a page and set its Value property.
