can give me solution?
you should try setting form on $this.
protected function _prepareform() { $form = new varien_data_form(array( 'id' => 'edit_form', 'action' => $this->geturl('*/*/process', array('id' => $this->getrequest()->getparam('id'))), 'method' => 'post', 'enctype' => 'multipart/form-data' ) ); $this->setform($form); return parent::_prepareform(); } furthermore recommend using container (extends mage_adminhtml_block_widget_form_container) around form.
