ExecuteNonQuery requires an open and available Connection. The connection's current state is closed

Question

ExecuteNonQuery requires an open and available Connection. The connection\'s current state is closed.

What am I doing wrong here? I\'m assuming you can

Answer 1

It appears you are doing a read before doing your ExecuteNonQuery. In your first call to SqlCommand (for the SELECT), you are closing the connection after the read is complete.

SqlDataReader rdr = cmd.ExecuteReader(CommandBehavior.CloseConnection);

Remove the command behavior, you should be good to go, or re-open the connection in your next if statement.

This

SqlDataReader rdr = cmd.ExecuteReader();

Or this

if (rowsReturned == true){
   cn.open();
