Hi all,
I have tried lot of different methods to refresh the parent webpage of a pop up window.
All of my methods failed for the moment using javascript .


Basically i am opening a new window from a Sharepoint webpage.
When I click "submit" on the op up window the sharepoint webpage should be refresh.
So far i have to do manually F5.
