i found an search demo on net but it uses php language..please help me how to convert it into web method.
USING PHP
calling method in php source
$.post("rpc.php", {queryString: ""+inputString+""}, function(data) { // Do an AJAX call
$('#suggestions').fadeIn(); // Show the suggestions box
$('#suggestions').html(data); // Fill the suggestions box
});
------------------
<p id="searchresults">
<?php
// PHP5 Implementation - uses MySQLi.
// mysqli('localhost', 'yourUsername', 'yourPassword', 'yourDatabase');
$db = new mysqli('localhost', 'sa', 'admin1', 'search');
if(!$db) {
// Show error if we cannot connect.
echo 'ERROR: Could not connect to the database.';
} else {
// Is there a posted query string?
if(isset($_POST['queryString'])) {
$queryString = $db->real_escape_string($_POST['queryString']);
// Is the string length greater than 0?
if(strlen($queryString) >0) {
$query = $db->query("SELECT * FROM search s INNER JOIN categories c ON s.cat_id = c.cid WHERE name LIKE '%" . $queryString . "%' ORDER BY cat_id LIMIT 8");
if($query) {
// While there are results loop through them - fetching an Object.
// Store the category id
$catid = 0;
while ($result = $query ->fetch_object()) {
if($result->cat_id != $catid) { // check if the category changed
echo '<span class="category">'.$result->cat_name.'</span>';
$catid = $result->cat_id;
}
echo '<a href="'.$result->url.'">';
echo '<img src="search_images/'.$result->img.'" alt="" />';
$name = $result->name;
if(strlen($name) > 35) {
$name = substr($name, 0, 35) . "...";
}
echo '<span class="searchheading">'.$name.'</span>';
$description = $result->desc;
if(strlen($description) > 80) {
$description = substr($description, 0, 80) . "...";
}
echo '<span>'.$description.'</span></a>';
}
echo '<span class="seperator"><a href="http://www.marcofolio.net/sitemap.html" title="Sitemap">Nothing interesting here? Try the sitemap.</a></span><br class="break" />';
} else {
echo 'ERROR: There was a problem with the query.';
}
} else {
// Dont do anything.
} // There is a queryString.
} else {
echo 'There should be no direct access to this script!';
}
}
?>
</p>
USING WEB METHOD IN C#

data: "{'search':'" + inputString + "'}",
//dataType: "json",
dataType: "html",
success: function(data) {
$('#suggestions').fadeIn(); // Show the suggestions box
$('#suggestions').html(data); // Fill the suggestions box
//response(data.d);
},
error: function(result) {
alert("Error");
}
});

[WebMethod]
public static List<string> GetAutoCompleteData(string search)
{
List<string> result = new List<string>();
String strConnString = System.Configuration.ConfigurationManager.ConnectionStrings["searchConnectionString"].ConnectionString;
SqlConnection con = new SqlConnection(strConnString);
using (con)
{
using (SqlCommand cmd = new SqlCommand("SELECT * FROM search_content s INNER JOIN categories c ON s.cat_id = c.cid WHERE name LIKE '%'+@SearchText+'%' ORDER BY cat_id", con))
{
con.Open();
cmd.Parameters.AddWithValue("@SearchText", search);
SqlDataReader dr = cmd.ExecuteReader();
while (dr.Read())
{
result.Add("<span class="+"\"category\""+">"+ dr["cat_name"].ToString()+"</span>");
