Syntax
Visual Basic (Declaration)
<LocalizableAttribute(True)> _
<BindableAttribute(True, BindingDirection.TwoWay)> _
Public Overridable Property Text As String
Dim instance As TextBox
Dim value As String
value = instance.Text
instance.Text = value
[LocalizableAttribute(true)]
[BindableAttribute(true, BindingDirection.TwoWay)]
public virtual string Text { get; set; }
[LocalizableAttribute(true)]
[BindableAttribute(true, BindingDirection::TwoWay)]
public:
virtual property String^ Text {
String^ get ();
void set (String^ value);
}
/** @property */
public String get_Text ()
/** @property */
public void set_Text (String value)
public function get Text () : String
public function set Text (value : String)
Property Value
The text displayed in the
TextBox control. The default is an empty string ("").
Remarks
Use the Text property to specify or determine the text displayed in the TextBox control. To limit the number of characters accepted by the control, set the MaxLength property. If you want to prevent the text from being modified, set the ReadOnly property.
The value of this property, when set, can be saved automatically to a resource file by using a designer tool. For more information, see LocalizableAttribute and ASP.NET Globalization and Localization.
Example
The following code example demonstrates how to use the Text property to specify the text displayed in the TextBox control.
