Class TTextBox

Description

Implements interfaces:

TTextBox class

TTextBox displays a text box on the Web page for user input. The text displayed in the TTextBox control is determined by the Text property. You can create a SingleLine, a MultiLine, or a Password text box by setting the TextMode property. If the TTextBox control is a multiline text box, the number of rows it displays is determined by the Rows property, and the Wrap property can be used to determine whether to wrap the text in the component.

To specify the display width of the text box, in characters, set the Columns property. To prevent the text displayed in the component from being modified, set the ReadOnly property to true. If you want to limit the user input to a specified number of characters, set the MaxLength property. To use AutoComplete feature, set the AutoCompleteType property.

If AutoPostBack is set true, updating the text box and then changing the focus out of it will cause postback action. And if CausesValidation is true, validation will also be processed, which can be further restricted within a ValidationGroup.

WARNING: Be careful if you want to display the text collected via TTextBox. Malicious cross-site script may be injected in. You may use SafeText to prevent this problem.

NOTE: If you set Wrap to false or use AutoCompleteType, the generated HTML output for the textbox will not be XHTML-compatible. Currently, no alternatives are available.
