To use a Stored Procedure in an AutoComplete extender TextBox in ASP.Net C# use the following procedure.

Open SQL Server Management Studio then

select the database where you want to create a table and Stored Procedure (in my case it is the library database and the table name is available book).
CREATE TABLE [dbo].[AvailableBook](

[Title] [varchar](500) NULL,

[Authorname] [varchar](100) NULL,

[Edition] [varchar](max) NULL,

[Year] [varchar](max) NULL,

[Volume] [varchar](max) NULL,

[BookNo] [varchar](max) NULL,

[ShelfNO] [varchar](50) NULL,

[enrollment] [varchar](50) NULL,

[Issuedate] [varchar](max) NULL,

[Returndate] [varchar](50) NULL,

[Status] [varchar](50) NULL,

[Bookid] [varchar](max) NULL,

[Type] [varchar](max) NULL

)

Insert values into the availablebook table like this:

insert into availablebook values('c#','apress','2011','2010','3','1','2','NULL','NULL','NULL','Available','1','NULL')
Create a Stored Procedure like this:

Create proc [dbo].[searchbook]

@book varchar(90)='%'

as

begin

select Title,Authorname from availablebook where title like @book or authorname like @book

end

After that open Visual Studio then open your project or create a new project.

Drag and drop a TextBox to your webform, in design view you are getting an arrow like addextender, see the following figure:

Select AutoCompleteExtender (don't forget to add a toolkit scriptmanager and reference it in your page header or in web.config).

See example :(aspx page source view)

Add a webservice from a new item and reference it in your project and write the following code (be careful while giving the webservice name; in my case it is WebService.asmx).

[WebMethod]

    Public List<string> GetCompletionList(string prefixText)

    {

        List<string> result = new List<string>();

        con.Open();

        SqlCommand cmd = new SqlCommand("searchbook", con);

        cmd.Parameters.AddWithValue("@book", prefixText);

        SqlDataReader dr = cmd.ExecuteReader();

        while (dr.Read())

        {

            result.Add(dr["Title"].ToString());

            result.Add(dr["Authorname"].ToString());

        }

        return result;

    }
