Problem in creating edit form container of a grid in admin Panel

[aishwaryacedcoss]

I have created a edit form functions some thing like this:-

namespace Excercise\Weblog\Block\Adminhtml\Blogpost;

class Edit extends \Magento\Backend\Block\Widget\Container { protected $_coreRegistry = null;

/**
 * @param \Magento\Backend\Block\Template\Context $context
 * @param \Magento\Registry $registry
 * @param array $data
 */
public function __construct(
    \Magento\Backend\Block\Template\Context $context,
    \Magento\Framework\Registry $registry,
    array $data = array()
) {

    $this->_coreRegistry = $registry;
    parent::__construct($context, $data);
}
/**
 * 
 * Retrieve text for header element depending on loaded page
 *
 * @return string
 */
protected function _construct()
{

    $this->_objectId = 'blogpost_id';
    $this->_blockGroup = 'Excercise_Weblog';
    $this->_controller = 'adminhtml_blogpost';

    parent::_construct();

    $this->_updateButton('save', 'label', __('Save Post'));
    $this->_addButton(
            'saveandcontinue',
            array(
                    'label' => __('Save and Continue Edit'),
                    'class' => 'save',
                    'data_attribute' => array(
                            'mage-init' => array(
                                    'button' => array('event' => 'saveAndContinueEdit', 'target' => '#edit_form')
                            )
                    )
            ),
            -100
    );

    $this->_updateButton('delete', 'label', __('Delete Post'));
}

public function getHeaderText()
{
    if ($this->_coreRegistry->registry('blog_post')->getId()) {
        return __("Edit Post '%1'", $this->escapeHtml($this->_coreRegistry->registry('blog_post')->getTitle()));
    } else {
        return __('New Post');
    }
}

Then Error comes as:- a:4:{i:0;s:142:"Invalid method Excercise\Weblog\Block\Adminhtml\Blogpost\Edit::_updateButton(Array ( [0] => save [1] => label [2] => Save Post )

I cant understand where the Problem is existing????Please help me???,my edit controller is:-

namespace Excercise\Weblog\Controller\Adminhtml\Blogpost;

class Edit extends \Excercise\Weblog\Controller\Adminhtml\Blogpost\Index {

protected $_coreRegistry = null;

/**
 * @var \Magento\Framework\Stdlib\DateTime\Filter\Date
 */
protected $_dateFilter;

  public function execute()
   {

    $this->_title->add(__('Blog Post'));

    // 1. Get ID and create model
    $id = $this->getRequest()->getParam('id');
    $model = $this->_objectManager->create('Excercise\Weblog\Model\Blogpost');

    // 2. Initial checking
 if ($id) {
        $model->load($id);
        if (!$model->getId()) {
            $this->messageManager->addError(__('This post no longer exists.'));
            $this->_redirect('*/*/');
            return;
        }
    }

    $this->_title->add($model->getId() ? $model->getTitle() : __('New Blog Post'));

    // 3. Set entered data if was error when we do save
    $data = $this->_objectManager->get('Magento\Backend\Model\Session')->getFormData(true);
    if (!empty($data)) {
        $model->setData($data);
    }

    // 4. Register model to use later in blocks
    //$this->_coreRegistry->register('blog_post', $model);

    // 5. Build edit form
    $this->_initAction()->_addBreadcrumb(
            $id ? __('Edit Post') : __('New Post'),
            $id ? __('Edit Post') : __('New Post')
    );

    $this->_view->renderLayout();
}

}

@aishwaryacedcoss Use this instead:

$this->buttonList->update('save', 'label', __('Save Post'));

and while you are at it, change the way the save and continue button is added because you will get an error after fixing the issue above

 $this->buttonList->add(
        'save-and-continue',
        [
            'label' => __('Save and Continue Edit'),
            'class' => 'save',
            'data_attribute' => [
                'mage-init' => [
                    'button' => [
                        'event' => 'saveAndContinueEdit',
                        'target' => '#edit_form'
                    ]
                ]
            ]
        ],
        -100
    );

It is saying :- undefined property: Excercise\Weblog\Block\Adminhtml\Blogpost\Edit::$buttonList in /opt/lampp/htdocs/workspace/magento2/app/code/Excercise/Weblog/Block/Adminhtml/Blogpost/Edit.php on line 39";i:1;s:10863:"#0 /opt/lampp/htdocs/workspace/magento2/app/code/Excercise/Weblog/Block/Adminhtml/Blogpost/Edit.php(39): Magento\Framework\App\ErrorHandler->handler(8, 'Undefined prope...', '/opt/lampp/htdo...', 39, Array)

@aishwaryacedcoss Make your block extend \Magento\Backend\Block\Widget\Form\Container because that's what the edit block is...a form container. But that's not really important, you should still be able to access the buttonList member. Since your class extends \Magento\Backend\Block\Widget\Container that has a member buttonList it should be available in the child classes. Clear the cache and var/generation just to be safe.

@aishwaryacedcoss can you try calling the inherited updateButton method?

If that still doesn't work can you post your latest code so we can help further?
