You cannot use DataPager along with DataList as the error says DataList control does not implements IPageableItemContainer.

You can use ListView control instead of DataList.

or

Check Efficient Data Paging with DataList[^].

All the best

thanks
I am certain the error is accurate. Perhaps if you post your code ?
   
asp.net 2.0 doesnot support Listview
