Refresh parent page when model dialog page is opened

When you want to refresh the parent page when user clicks on OK button on dialog page that you open from the parent page then you can use SP.UI.ModalDialog.RefreshPage


Usually we write this code in dialogReturnCallBack function.

       dialogReturnValueCallback: function(dialogResult) 
        { 
          SP.UI.ModalDialog.RefreshPage(dialogResult) 
        }
