If we call the below code in a controller, it renders the complete layout handle related to the controller.


But what I want is to render only a particular block from the layout handle.

Lets say if my layout handle has a child block with name "hello", I want to render that particular block. How to do this?

I tried the below code:

    $layout = $this->getLayout();
    $block = $layout->getBlock("hello");
    $block->renderLayout(); /* Error: 503 Service Unavailable */

Try like this:

$layout = $this->getLayout();
$block = $layout->getBlock("hello");
echo $block->toHtml();

For ajax requests do this:
