As mentioned in other answers asymmetric encryption is only designed for encrypting data smaller than its key size. One option that I have implemented when needing to transfer large amounts of encrypted data between two systems is to have an RSA keypair whose public key is known to both the sender and the receiver then when data needs to be sent the receiver generates a new RSA keypair, encrypts the public key of that keypair with the common public key and sends the encrypted public key to the sender. The sender decrypts the receivers public key using its private key (which the receiver does not need to know, just as the sender does not need to know the receivers generated private key), generates a symmetric encryption key, encrypts the data with the symmetric key and then encrypts the symmetric key using the public key received from the receiver. Both the encrypted symmetric key and the encrypted data are then sent to the receiver which uses its generated private key to decrypt the symmetric key and then decrypts the data. You can use the <code>RSACryptoServiceProvider.ToXMLString()</code> and <code>RSACryptoServiceProvider.FromXMLString()</code> methods to store the common public key as an XML string literal in the receiver application. Don't forget, when you generate the symmetric encryption key to use <code>RNGCryptoServiceProvider()</code> to generate the key as it is a much more secure method of generating (pseudo) random numbers. Also, I strongly recommend against using 3DES as your symmetric encryption algorithm, it is old and starting to show its age. Use AES symmetric encryption with either the <code>AesCryptoServiceProvicer</code> or <code>RijndaelManaged</code> classes.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
