I am developing an asp.net c# application.
I need to implement a textbox in which the user enters a character (or more
then 1) and a dropdownlist is filled according to that character (it is filled
with all of the strings the begin with that character). it's like an
auto-complete control. I want to do sql connection. when i enter any character in autocomplete textbox it should display d string starting with that character when i select any string it should display relevant field of selected string in dropdown list.
How can i do that?
Please help me
