PHP Class Prado\Web\UI\WebControls\TTextBox

TTextBox displays a text box on the Web page for user input. The text displayed in the TTextBox control is determined by the {@link setText Text} property. You can create a SingleLine, a MultiLine, or a Password text box by setting the {@link setTextMode TextMode} property. If the TTextBox control is a multiline text box, the number of rows it displays is determined by the {@link setRows Rows} property, and the {@link setWrap Wrap} property can be used to determine whether to wrap the text in the component. Additional {@link setTextMode TextMode} types enable the use of new input types added with html5, eg. Color, Date, Email. To specify the display width of the text box, in characters, set the {@link setColumns Columns} property. To prevent the text displayed in the component from being modified, set the {@link setReadOnly ReadOnly} property to true. If you want to limit the user input to a specified number of characters, set the {@link setMaxLength MaxLength} property. To use AutoComplete feature, set the {@link setAutoCompleteType AutoCompleteType} property. If {@link setAutoPostBack AutoPostBack} is set true, updating the text box and then changing the focus out of it will cause postback action. And if {@link setCausesValidation CausesValidation} is true, validation will also be processed, which can be further restricted within a {@link setValidationGroup 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 {@link getSafeText SafeText} to prevent this problem. NOTE: If you set {@link setWrap Wrap} to false or use {@link setAutoCompleteType AutoCompleteType}, the generated HTML output for the textbox will not be XHTML-compatible. Currently, no alternatives are available.
