Hi Ali, The best thing to do would be implementing your own data model, as you should anyway. The datascroller is based on element count, not on specific start/end characters. So, something completely different.
What you want to do is use simple java methods that are bound to your data model. For example, if you are using hibernate, you would initially collect all the elemtents and filter them into result sets, starting with the desired letter. You could achieve that by making speficic statements... Fill a selectOneMenu with all the start-letters you have and onchange perform a select on your database that fits your needs. Using a dataScroller-like element for that would look ugly. Do you really want to have 26 letters visible to the user at all time? Better take a pulldown menu like the selectOneListBox, and only fill it with those letters that are actually available, which you collected on init. Anyway... If you are not using hibernate or any database, just plain lists the come from whereever, you could just use the method startsWith(String s) on the type String. Building your own component for that would be a real bloat from my point of view.
