Add the following code in your execute function of Save Controller (Module/Controller/Adminhtml/Example/Save.php)

 public function execute()
    {
        $resultRedirect = $this->resultRedirectFactory->create();
        $data = $this->getRequest()->getPostValue();

        if ($data) {
            try{
                $id = $data['id'];
                $customModel = $this->customModel->load($id);
                $data = array_filter($data, function($value) { return $value !== ''; });
                $customModel->setData($data);
                $customModel->save();

                $this->messageManager->addSuccess(__('Successfully saved the item.'));
                $this->_objectManager->get('Magento\Backend\Model\Session')->setFormData(false);                
                return $resultRedirect->setPath('*/*/');
            } catch (\Exception $e) {               
                $this->messageManager->addError($e->getMessage());
                $this->_objectManager->get('Magento\Backend\Model\Session')->setFormData($data);
                return $resultRedirect->setPath('*/*/edit', ['id' => $customModel->getId()]);
            }
        }
        return $resultRedirect->setPath('*/*/');
    }
