Hi Daniel,
Welcome to ASP.NET newsgroup. As for the modifying the ASP.NET DataGrid's
buildin pager style's question. I think we may start from the following
means:
The ASP.NET's Buildin pager is rendered in the Pager Section of the
datagrid, we can access that section through the ItemCreated event. The
Pager section is infact an TableCell , and all the number, [...] links are
all Linkbuttons in that TableCell. So if you want to do any modification or
customization, we should manually access that TableCell and modify it's
Controls colleciton. Here is a test page I've built, you can have a look:

There are also many tech articles over other internet development community
discussing on the similiar problem. HTH.
