Hi again,

Mono, I have a problem. :)

It appears that the DataGrid control doesn't do "paging" (or custom paging)
I guess...
Maybe I am doing something wrong, but can you check this ? perhaps in cvs is
corrected, no?
When clicking the "table page number" on the bottom of the datagrid table it
doesn't change the "table page" to the selected one...

In Suse8.2:
Using all latest RPMs!! NOT from cvs !!
    # mono --version
    Mono JIT compiler version 0.28, (C) 2002, 2003 Ximian, Inc.

    # mcs --version
    Mono C# compiler version 0.27.0.0

    XSP-0.6

Thanks in advance,
    Tiago Lima
