In ASP.Net Show Favourite Cities on top in a Dropdown List bound to City Table

In ASP.Net, I have a Dropdown List bound to a City Table with City Id as Value & City names as Data Text field.
I want to Show a few Favourite Cities on top as well as in their correct place in the Dropdown List. Help!

Have you tried doing this in sql?

what is your criteria to make a city favourite???
I propose to give a Ranking to every city and store it in a field(say city_ranking) in your table

Now u can easily have your favourite city with a sql like

SELECT city_name FROM tblCity WHERE city_ranking>50

User will mark a few cities as favourites- which he might need frequently.
I want to show favourite city (ranking >10) on top of the list but the complete list should also appear below those cities.
I need the text & also Value- CityId of each ListItem. As I'll insert the CityId of the selected city in my Prospects Table. I want favourite cities on top as the user should not waste time in searching the list. The ranking can be changed when ever user wishes.
eg. Dropdown list should look like this:(Delhi has rank 1, Banglore 2 & Hyderabad 3). If I have to enter US,UK prospects, I'll mark NY, London as my favourites.

Delhi
Banglore
Hyderabad
----------
Alicante
Banglore
Barcelona
Basel
Buchrain Luzern
Dällikon
Delhi
Igualada
Hyderabad
Madrid
Shanghai

If you have a specific Raking system then you can just write the sql as

SELECT city_name,city_id FROM tblCity ORDER BY city_ranking

this sql will give the desired result you want.You can use ASC(Ascending) and DESC(Descending) clause with ORDER BY according to your Ranking system

Thanx a lot for your interest.
I would sort my list if I want Favourite entries on top only. But Pl note that those favourite cities are coming twice- once on top (then a separator) & second time in their normal place (Alphabetical order). And duplicate entries would not be allowed because of duplicate Data Value field. I have seen such lists in some website.

I had to do something similar to this.
After you have binded the dropdown, do an insert at index positions to add them in.

So say you have a data object with all the items and a data object with all the favorite items. You would bind to the object with ALL the items, then itterate through the object with favorites, using the insert at index function to place them at the top.

I don't have VS on my computer right now so I can't provide source code, but hopefully that will be enough for you to find what you need.

Thanks a lot! I had thought that if 2 listitems have same value (CityId) in a list, some problem would be there. But your idea is working!
