Hi Novo,
SetVirtualCount doesn't appear to change anything. It still takes a minute or more to load up the data from my data structures into the ArrayCtrl one row at a time using ArrayCtrl::Set(int row, Vector<Value> vals); Is there a quicker way please? I can't see anything in the popup list of functions.
Cheers,
Nick

 The secret of virtual array is that you do not need to load data into it.
You need to do two things:
1) Set number of virtual rows by calling SetVirtualCount().
2) Set converters for your columns, which will convert row number into data you want to display.
Take a closer look at
warray.AddRowNumColumn("lemma", 80).SetConvert(*Number2Lexeme);
There is an app VirtualArray in the "reference" assembly.
Regards,
Novo
