no built in Virtual mode.

Sure there is

wxGrid::SetTable

Use this function instead of CreateGrid() when your application involves complex or non-string data or data sets that are too large to fit wholly in memory.

The virtual class is wxGridTableBase

Perl example is  wxperl_demo --show "Custom wxGridTable"

It shows inheriting being derived from Wx::PlGridTable and Wx::PlGridTable @ISA = qw(Wx::GridTableBase);, this is the wxperl way for virtual classes as Wx::NewClass explains

http://wiki.wxperl.nl/Wx::GridTableBase mentions this

Also some related info at Software Woes: wxGrid with virtual storage and multirow or multicolumn cells
