Hello people,

I have a database in which i have a movies table it has two columns : Id and Movie.
I have used an autocomplete extender to extend the text box i have used LINQ to sql and written the web method.
Please look into it:

C#

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>
<%@ Register TagPrefix="ajax" Namespace="AjaxControlToolkit" Assembly="AjaxControlToolkit" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script type="text/javascript">
    
      function pageLoad() {
      }
    
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div style="height: 223px">
        <asp:ScriptManager ID="ScriptManager1" runat="server" />
        <asp:Label ID="title" Text="Movie" AssociatedControlID="tb" runat="server" />
        <asp:TextBox ID="tb" runat="server" />
        <ajax:AutoCompleteExtender ID="ace1" TargetControlID="tb" 
             MinimumPrefixLength="1"  runat="server" 
            UseContextKey="True" ServiceMethod="GetCompletionList" />
          <asp:Button runat="server" OnClick="click" Text="submit" />
          <br /><br />
          
         <asp:Label ID="lbl" runat="server" />
    </div>
 
    </form>
</body>
</html>

code behind:

C#

protected void Page_Load(object sender, EventArgs e)
{


}
protected void click(object sender, EventArgs e)
{
    lbl.Text = tb.Text;
}
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public static string[] GetCompletionList(string prefix, int count)
{
    DataClassesDataContext db = new DataClassesDataContext();
    return db.movies
        .Where(m => m.Movie.StartsWith(prefix)).OrderBy(m => m.Movie).Select(m => m.Movie).Take(count).ToArray();

}

Thanks and regards
