Due to this when I select fields and apply mass action error appears ie 'Please select items.'

For reference please find the snaps below:

Still getting error:

Any Kind of help would be appreciated..

Answer 1

You can get it working with jquery by writing following code :

jQuery('a:contains("Select All")').click();

On the document ready in page where you want to autoselect all items in a grid.

Answer 2

I found the issue.

In the mass action field I have set wrong name. Once I replaced it with the correct index name of the column the issue is resolved.

A snippet of the code is as follows:

parent::_prepareMassaction();
$this->setMassactionIdField('entity_id');
$this->setMassactionIdFilter('entity_id');
$this->setMassactionIdFieldOnlyIndexValue(true);
$this->getMassactionBlock()->setFormFieldName('sellers');
