I am using the Content Query Web part - (CWQP) for displaying the news items. I am able to filter the news items and display it. Followed the link :

It works!!!

I need to further customize the CQWP. Currently I am displaying the news item for the current month. I need to show the news item for the previous month using a previous button << on the CQWP web part ( which will give me the news item for the previous month)...(..the filter can be on the begins and expirydate...I feel).

1. Can any 1 help me in how to add a button on the CQWP

2. Also, how can I retrieve the previous month news item

Any help would be highly appreciated
