Customize "Mark As Read" button in View unread threads page

Jun 23, 2014 at 3:44 PM
I'm using DNN_Forum (version 5.0.3) module in my DNN 6.2 application.

When i click on "Mark As Read" button, the Threads displaying on the current page are only moving into Read Threads list. I want to Mark all the Threads in the View unread threads as Read when I click on "Mark As Read" button.

Please suggest the code changes needed for this customization.
