Magento Admin has a store select drop down list of all the stores.
I have added an addititional “SELECT ALL STORES” value to allow me to know when a user wishes to carry out a task on all stores.
I based this customisation on enterprise magento version 1.9 although I think the version is quite irrelevant since my question is quite generic to magento I think.
How do I stop my “SELECT ALL STORES” from being selected by default in the search ?
/index.php/admin/admin/urlrewrite/index
The store list select form is built here:
app\code\core\Adminhtml\Block\Widget\Grid\Column\Filter\Store.php
Once I found that, I could override it to the local code pool and make the modifications I needed.
