I've a form with multiple tabs and in one tab there is a grid with mass actions.

But when i click on Submit button, after selecting the massaction, the control is redirected to dashboard.

enter image description here

this is the code to get the mass action 

protected function _prepareMassaction()
    {
        $this->setMassactionIdField('sku_id');
        $this->getMassactionBlock()->setTemplate('Namespace_Module::massaction_extended.phtml');
        //$this->setMassactionIdFieldOnlyIndexValue(true);
        $this->getMassactionBlock()->setFormFieldName('universalProductsGrid');

        $this->getMassactionBlock()->addItem(
            'delete',
            [
                'label' => __('Remove Global SKUs'),
                'url' => $this->getUrl('namespace_module/*/massDeleteSku',['id'=>$this->getRequest()->getParam('id')]),
                'confirm' => __('Are you sure?')
            ]
        );
        return $this;
    }

EDIT I have found the problem, the form_key was not rendered in the massaction form, so temporary i added the below function in the file

magento-root/vendor/magento/module-backend/Block/Widget/Grid/Massaction/Extended.php

public function getFormKey()
    {
        return $this->formKey->getFormKey();
    }

and then in the file Namespace_Module::massaction_extended.phtml

replaced <?php echo $block->getBlockHtml('formkey')?> with 

<input name="form_key" type="hidden" value="<?php //echo $block->getFormKey() ?>" />

But now my problem is how do i change this in my module block, instead of changing the core block.

Thanks.

You can add formkey using <update handle="formkey"/> inside your all grid related layout xml files.

ex.module_index_grid.xml code for test,

<?xml version="1.0"?>

<layout xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/layout_generic.xsd">
   <update handle="formkey"/>

   <body> 
         //code for body
   </body>
</layout>

Try using this.
