Down i want to display <BR>A B C D E F G H I J K L M N O P Q R S T U V W X Y Z. When the visitor clicks any alphabet i want to display all the data in Cities starting with those alphabet. <BR><BR>is there any control available ? or could anyone give logic how i can write these ? <BR><BR>what i did ? <BR><BR>Problem is i want to display records when they click the categories. (all cities). when they click alphabets i want to display records ONLY those cities. (so two events). Listing by alphabet is optional. <BR><BR>i tried with linkbutton onclick event, but i don&#039;t know how to pass &#039;A&#039; or &#039;B&#039; ... to function or subroutine from link button command. i am going for event because i need to get Categories in Request.Params command. <BR><BR>Please help.
