    You can use command object to pass parameter to sql query.

    SqlConnection conn = new SqlConnection(CONNECTIN_STRING);
    SqlCommand command = conn.CreateCommand();
    command.CommandType = CommandType.Text;
    command.CommandText = "SELECT * FROM Table_Name WHERE
    field_Name = parameter";
    command.Parameters.Add("parameter",value);
    SqlDataAdapter dap = new SqlDataAdapter(command);

    So add a parameter to the DataAdapter.SelectCommand.Parameters collection:

    DataAdapter1.SelectCommand.CommandText = "select * from foo where bar = bar";
    DataAdapter1.SelectCommand.Parameters.Add("bar", "some value");
