The {@link OnLoadingText} event allows * you to update the content of the textbox before the client is allowed * to edit the content. After the callback request returns successfully, * the textbox is enabled and the contents is then allowed to be edited. * * Once the textbox loses focus, if {@link setAutoPostBack AutoPostBack} * is true and the textbox content has changed, a callback request is made and * the {@link OnTextChanged} event is raised like that of the TActiveTextBox. * During the request, the textbox is disabled. * * After the callback request returns sucessfully, the textbox is enabled. * If the {@link setAutoHideTextBox AutoHideTextBox} property is true, then * the textbox will be hidden and the label is then shown. * * Since 3.1.2, you can set the {@link setReadOnly ReadOnly} property to make * the control not editable. This property can be also changed on callback * * @author Wei Zhuo <weizhuo[at]gmail[dot]com> * @version $Id$ * @package System.Web.UI.ActiveControls * @since 3.1 */ class TInPlaceTextBox extends TActiveTextBox { /** * Sets the auto post back to true by default. */ public function __construct() { parent::__construct(); $this->setAutoPostBack(true); } /** * @param boolean true to hide the textbox after losing focus. */ public function setAutoHideTextBox($value) { $this->setViewState('AutoHide', TPropertyValue::ensureBoolean($value), true); } /** * @return boolean true will hide the textbox after losing focus. */ public function getAutoHideTextBox() { return $this->getViewState('AutoHide', true); } /** * @param boolean true to display the edit textbox */ public function setDisplayTextBox($value) { $value = TPropertyValue::ensureBoolean($value); $this->setViewState('DisplayTextBox', $value,false); if($this->getActiveControl()->canUpdateClientSide()) $this->callClientFunction('setDisplayTextBox',$value); } /** * @return boolean true to display the edit textbox */ public function getDisplayTextBox() { return $this->getViewState('DisplayTextBox', false); } /** * Calls the client-side static method for this control class. * @param string static method name * @param mixed method parmaeter */ protected function callClientFunction($func,$value) { $client = $this->getPage()->getCallbackClient(); $code = $this->getClientClassName().'.'.$func; $client->callClientFunction($code,array($this,$value)); } /** * @param string ID of the control that can trigger to edit the textbox */ public function setEditTriggerControlID($value) { $this->setViewState('EditTriggerControlID', $value); } /** * @return string ID of the control that can trigger to edit the textbox */ public function getEditTriggerControlID() { return $this->getViewState('EditTriggerControlID'); } /** * @return string edit trigger control client ID. */ protected function getExternalControlID() { $extID = $this->getEditTriggerControlID(); if($extID===null) return ''; if(($control = $this->findControl($extID))!==null) return $control->getClientID(); return $extID; } /** * On callback response, the inner HTMl of the label and the * value of the textbox is updated * @param string the text value of the label */ public function setText($value) { TTextBox::setText($value); if($this->getActiveControl()->canUpdateClientSide()) { $client = $this->getPage()->getCallbackClient(); $client->update($this->getLabelClientID(), $value); $client->setValue($this, $value); } } /** * Update ClientSide Readonly property * @param boolean value * @since 3.1.2 */ public function setReadOnly ($value) { $value=TPropertyValue::ensureBoolean($value); TTextBox::setReadOnly($value); if ($this->getActiveControl()->canUpdateClientSide()) { $this->callClientFunction('setReadOnly', $value); } } /** * @return string tag name of the label. */ protected function getTagName() { return 'span'; } /** * Renders the body content of the label. * @param THtmlWriter the writer for rendering */ public function renderContents($writer) { if(($text=$this->getText())==='') parent::renderContents($writer); else $writer->write($text); } /** * @return string label client ID */ protected function getLabelClientID() { return $this->getClientID().'__label'; } /** * This method is invoked when a callback is requested.
