Hi,

I know about GridDataSource and have implemented that already. The
problem I face is that I do not know how many rows the GridDataSource
will return. I only know if there is more data the moment I request the
data.

Would it be possible to specify MAXINT rows, remove the pager and create
my own pager that only contains a previous and next link?
