$block->getLayout() ->createBlock('Magecomp\Crud\Block\GetUserById','magecompcrud.edituser',['data'=>['userid'=>$userid]]);

Now how can I access this userid in blcok or blcok method

Answer 1

you can use setData after createBlock

example

$block->getLayout()->createBlock()->setData('key',value)

To retrieve data from block

$block->getData('key');
