store multiple value in database using only one save

first of all you can store the total information in one DataTable/DataSet then using foreach you can do this stuff. Inside foreach you write your inserting query...

ex:

DataTable dt=/// your data;
foreach ( DataRow dr in dt.Rows)
{
    //inserting query..
}

it's better to use a collection which holds both key and value pairs
I mean to use Hashtable to store all the properties from 5 controls. While you are doing any activity (moving from one control to another control) save your details in hashtable.
After that prepare a query based on the values you collected in hashtable and submit your insert or update query to DB server.

once your query executed remove the memory from hashtable or clear the records.
