How to change admin page header title?

Question

How I can change page header title from controller in admin page?

In the picture I want to change Dashboard to something else. I tried below code in execute method of the controller

$pageFactory = $this->resultPageFactory->create();
$pageFactory->getConfig()->getTitle()->prepend(__("Your Title"));

It is adding the title to the browsers tab but not changing the header title in the main page. How to change main page title?

Below is the html shown on inspecting in the browser.

<div class="page-header-hgroup col-l-8 col-m-6">
<div class="page-title-wrapper">
    <h1 class="page-title">Dashboard</h1>
    </div>
</div>

I have also tried below code

 $this->_view->getLayout()->getBlock('page.main.title')->setPageTitle('Something else');
 $this->_view->renderLayout();

It says Error: Call to a member function setPageTitle() on bool.

Answer 1

its loading from below file

\vendor\magento\module-backend\Controller\Adminhtml\Dashboard\Index.php

Answer 2

This is the place where you can change the title -
your_installed_folder_root/vendor/magento/module-backend/Controller/Adminhtml/Dashboard/Index.php
Please check this screenshot at line number 41, you can edit it from here.

And I have tested it also. After replace then save and just do hard refresh browser will show you this change. As shown in the below picture.


EDITED: As your code is custom module so this is the file location is

/var/www/html/local_m241/lcl_m241/app/code/your_vendor/your_module/Controller/Adminhtml/Items/Index.php:

Test Items is the Heading here.

   15          $resultPage = $this->resultPageFactory->create();
   16          $resultPage->setActiveMenu('Biren_Crudimage::test');
   17:         $resultPage->getConfig()->getTitle()->prepend(__('Test Items'));
   18          $resultPage->addBreadcrumb(__('Test'), __('Test'));
   19          $resultPage->addBreadcrumb(__('Items'), __('Items'));

Answer 3

I was able to make it work using below code in the controller:

 $this->_initAction();
 $this->_view->getLayout()->getBlock('blocks_blocks_edit');
 $this->_view->getPage()->getConfig()->getTitle()->prepend(__("test title")); // Added this line
 $this->_view->renderLayout();
