HtmlTextArea.ServerChange Event

Occurs when the content of the HtmlTextArea control changes between posts to the server.

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

public:
event EventHandler^ ServerChange {
	void add (EventHandler^ value);
	void remove (EventHandler^ value);
}
/** @event */
public void add_ServerChange (EventHandler value)

/** @event */
public void remove_ServerChange (EventHandler value)

JScript supports the use of events, but not the declaration of new ones.

The ServerChange event is raised when the content of the HtmlTextArea control changes between posts to the server. This event is commonly used to perform data validation on the text box.

NoteNote

This event is only raised when the user initiates a post to the server, such as clicking a submit button. This event does not cause a post to the server to occur.

NoteNote

The control must have viewstate enabled for the ServerChange event to work correctly.

For more information about handling events, see Consuming Events.

The following code example demonstrates how to specify and create a custom event handler for the ServerChange event. A message is displayed when the value entered in the HtmlTextArea control exceeds 10 characters.
