I've a drop-down, where I want to provide search as you type feature for the users. When user types any letter, all the items containing that letter should be shown in the drop-down.
Currently I am using ajaxToolkit:ListSearchExtender. It shows only those items starting from the provided letter.
e.g I've a drop-down containing the list of the continents Asia, Australia, Africa, South America, North America, Europe, Antarctica.
When the user types the letter N, ajaxToolkit:ListSearchExtender drop-down shows only North America, but I want to display every items that contain the letter N in the drop-down.
How can I extend this feature in ListSearchExtender to search any items in the drop-down that contain the typed letter but not just only at the beginning of the item?
Please help!!!
