Hello programmers, got a few problems here. All I want is that when I type on ... let say example a textbox or a dropdown,letter "A", All data from the database with starting letter "A" will be post below like a suggestion.. Basically I want to create something like google search box but it will be based on my database. If the user type something new, it will be added to my database. Any tutorial regarding this matter Sir/Madams?

Thanks in advance..

1. Bind the text box to a collection.
2. Load the collection with data from database on initialize.
3. On key press event, filter the collection with letter typed. You can use Link with collection, and use Find<> method which takes a predicate delegate.

How do you think this would perform if the database contained 100s or 1000s of records?
The key event would require a post back on each character. How will this perform?
Basically, a very poor solution

Use AJAX to handle post back. Thats what google does
