Increase value for Timeout of your SQL Connection & SQL Command
For Connection in Web.Config,
<add key=
"
ConnectionString"
value
=
"
server=(local); uid=sa; password=sa; database=master;Connection Timeout=30"
/>
For Command,
public
void
CreateSqlCommand()
SqlCommand cmd =
new
SqlCommand();
cmd.CommandTimeout =
15
;
cmd.CommandType = CommandType.Text;
& also take a look at the following page.

Increasing the command timeout will solve the problem, but you are addressing the issue rather than the cause
Default query timeout is 30 seconds, so assuming you haven't changed this your queries are taking 30 seconds to run and then reporting timeout.
Can you tune your queries at all?
* Are all tables included in the query correctly indexed. Clustered index on tables etc?
* Have you run your query through Execution Planner? Any areas that could be improved?
* Is only the data you need to update being updated?
You should definitely have a look at the source of the problem first and see if you can improve things here.
