That is the `configureCell` extension method on a PowerTable.

That method gets called for **every** cell in the table, and repeatedly called when the table scrolls or anything else makes it repaint.

Doing anything in that method that calls out across the network (any gateway tag read or database query or `system.net.*` operation) will **crush** your client.

Show the whole extension method so we can point out the flaws and make suggestions for alternate techniques. Paste and mark as code as described here:
