Hello,

I was trying to create a custom field type similar to lookup column just mine is filtered lookup column.Its working fine but I wanted to implement the same functionality like lookup column does,by that I mean:

For e.g lookup column is having title of some list so it stores its value as

SPListiem.ID#;title....but it shows only title when we r selecting or editing value in it.

I am using listboxes and doing

listbox.Items.Add(title);

but how to get Id also and specially hidden from users like lookup column does....means I can do like this... listbox.Items.Add(title+"#;" + SPListitem.ID)...

but I dont want this....

Any idea how to achieve this...
