Question

I have data like this in database table:

vehicle1 driver1 
vehicle1 driver2
vehicle2 driver3
vehicle3 driver4
vehicle3 driver5
vehicle4 driver6
vehicle4 driver7
vehicle4 driver8

I need to show drivers ordered by vehicles in asp.net dropdownlist. But I need to show drivers from vehicle X first where X is set up dynamically (programmatically).

So if X is vehicle3 the data in my dropdownlist would look like this:

**vehicle3 driver4**
**vehicle3 driver5**
vehicle1 driver1 
vehicle1 driver2
vehicle2 driver3
vehicle4 driver6
vehicle4 driver7
vehicle4 driver8

Any suggestions how to accomplish this?

If your data in SQL Server database then select the data as required.

SELECT A.Vehicle, A.Driver 
FROM (SELECT Vehicle, Driver, CASE @X WHEN Replace(Vehicle,'Vehicle','')
                              THEN 0 ELSE 1 END AS OrderCol 
      FROM yourTable ) A
ORDER BY A.OrderCol,A.Vehicle
