[Mono-list] asp.net and Npgsql namespace not found

[Alan Campbell]

Carl,

I pre-compiled the code, restarted XSP and the page loads fine with no errors.

However, I have now discovered an new problem.  I have an editable
datagrid with textboxes and I loop through the datagrid using
DataGrid1.Items.Count.  The DataGrid displays fine and under in WinXP
I can extract the textboxes from the DataGrid, but under Mono the
DataGrid.Items.Count property = 0.  I guess I will have to do some
more research.

Regarding C# books, I will browse the local bookstore when I am passing.

Alan.
