[DotNetDevelopment] Keep DataTable after postBack

[Ana]

Hi,

I'm binding a Data Table based on the Directory Structure and in
information retrieved from the DB. First I add all records from the
Data Base into the table and then I go through each node of a TreeView
(the TreeView matches the Directory Structure) and, if a record is not
in the Data Base (and consequently in the table), I add it to the
table.
Because this is a quite slow operation and I need the table a lot of
times, I would like to keep this DataTable even after a post back
occurs. Is this something possible, or every time I have to re-bind
the table?

Thanks,

Ana
