c# - How to use autocomplete extender multiple times in single textbox? -


i working on real estate based application in asp.net . here, want use autocomplete extender cities. have tried following

below design section have used textbox named "txtcity" along autocomplete extender target control "txtcity" , web service method "getcities".

<%@ register assembly="ajaxcontroltoolkit" namespace="ajaxcontroltoolkit" tagprefix="ajax" %> <html xmlns="http://www.w3.org/1999/xhtml">   <head runat="server">     <title>ajax autocompleteextender without webservice</title>   </head>   <body>     <form id="form1" runat="server">       <ajax:toolkitscriptmanager id="scriptmanager1" runat="server"/>       <div>         <asp:textbox id="txtcity" runat="server"></asp:textbox>         <ajax:autocompleteextender id="autocompleteextender1" runat="server"                targetcontrolid="txtcity" minimumprefixlength="1" enablecaching="true"                completionsetcount="1" completioninterval="1000" servicemethod="getcities" >         </ajax:autocompleteextender>       </div>     </form>   </body> </html>

below webservice method return names of cities in form of list.

using system.data; using system.data.sqlclient; using system.collections.generic; using system.configuration;   [system.web.services.webmethod] public static list<string> getcities(string prefixtext) {    sqlconnection con = new sqlconnection     (configurationmanager.connectionstrings["dbconnection"].tostring());   con.open();   sqlcommand cmd = new sqlcommand("select * city cityname     @name+'%'", con);   cmd.parameters.addwithvalue("@name", prefixtext);   sqldataadapter da = new sqldataadapter(cmd);   datatable dt = new datatable();   da.fill(dt);   list<string> coitynames = new list<string>();   (int = 0; < dt.rows.count; i++)   {      citynames.add(dt.rows[i][1].tostring());   }   return citynames;  }

here, when enter character cities matching character gets displayed in drop-down manner , after selecting city, selected city displayed in textbox.

when search city new city appears in textbox while selected city gets deleted. don't want selected cities disappear.

i want use functionality used in sites 99acres.com.

the exact functionality is being demonstrated using rad controls here http://demos.telerik.com/aspnet-ajax/autocompletebox/examples/default/defaultcs.aspx

you need set sql data source , bit of ajax wrapping.
