TextBoxBase Class

Implements the basic functionality required by text controls.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)
public abstract class TextBoxBase extends Control

This class implements the core features of text manipulation controls, such as TextBox and RichTextBox. These include text selection, Clipboard functionality, multiline text control support, and many events.

Notes to Inheritors:

You do not typically inherit from TextBoxBase. To create your own text control class, inherit from TextBox or RichTextBox.

The following code example uses TextBox, a derived class, to create a multiline TextBox control with vertical scroll bars. This example also uses the AcceptsTab, AcceptsReturn, and WordWrap properties to make the multiline text box control useful for creating text documents.

No code example is currently available or this language may not be supported.
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
