How to change date format?

Hi,
When we use a date field, it has a default placeholder value as "M/d/yyyy", however we have a client requirement where we need to display the placeholder value as "mm/dd/yyyy". Is there any way through which we can achieve this?. Instructions will also not work here since we are using date field in editable grid.
We are into a shared environment and making the changes to server settings will not help here.
Thank you in advance
