We have always hoped that Atlas will provide AutoComplete extension features, and we will be able to live up to expectations. This feature is already included in the latest ASP. NET Ajax Control Toolkit: autocompleteextender. It is easy to use.
The following is a stock.CodeFor example, enter a part of the Code, an abbreviation of Pinyin, or a Chinese character to get all the prompts.

1. Add a textbox.
<Asp: textbox runat = "server" id = "txtstockkeyname" width = "300" AutoComplete = "off"/>

2. Add autocompleteextender and set parameters.
<PC3: autocompleteextender
Runat = "server"
Id = "autocomplete1"
Targetcontrolid = "txtstockkeyname"
Servicepath = "stockcode. asmx"
Servicemethod = "getstocklist"
Minimumprefixlength = "1"
Completioninterval = "1000"
Enablecaching = "true"
Completionsetcount = "12"
/>
