Problem working with Datapager

Hi, i'm using asp.net 3.5, C#
I have a user control that uses DataPager and Liveview to display data that is return as a dataset table from a web service call.  The listview datasource is bind to the return datatable.  
1.  However, my Datapage doesn't seem to work when i click on any of the page it refreshes the page but still display the same data.
2.  There is a big gap about 2,3 inches before the listview starts displaying the data.  This gap was not there when I was uss DataList control to implement this.  
How can I correct these 2 problems?  thank you.
