PHP Class Prado\Web\UI\ActiveControls\TActiveTextBox

TActiveTextBox allows the {@link setText Text} property of the textbox to be changed during callback. When {@link setAutoPostBack AutoPostBack} property is true, changes to the textbox contents will perform a callback request causing {@link onTextChanged OnTextChanged} to be fired first followed by {@link onCallback OnCallback} event.
