my connection is:

the error is

Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding

and I try to add the proberty to my connection but this error occurred

The Connection Timeout attribute is not declared.


so please guide me to solve this problem.

You can add connection timeout to SQL query as follows:

SqlConnection con = new SqlConnection();
SqlCommand cmd = new SqlCommand();

cmd.Connection.ConnectionTimeout = 30;
cmd.CommandTimeout = 45;

and see if this solves the timeout issue.
