Have a look at the AjaxControlToolkit's AutoComplete extender. It can do what you are seeking:

The extender has a decent set of properties for controlling behavior and presentation.

but i want to make as composite custom control so how we use Ajax in custom control...

Laurence Adams Over a year ago

Are you sure you need a Composite Control? Would a User Control suffice? You can use Ajax within Composite Controls. You're just going to have to build the controls programmatically, it's really not all that different than laying out controls in an ascx/aspx. You'll want to be sure to account for pre-exsiting/non-existant ScriptManagers in the parent application. Here's a good starting point on Ajax within Composite Controls: stackoverflow.com/questions/592614/…

Personally, I am not a fan of the AjaxControlToolkit. I think the final code it produces is bloated and yucky.

I think I understand what you are asking, but tell me if I am wrong. You give the user a textbox, and as they type, each keystroke is examined, and under the textbox, a dropdown appears with possible results that match what the user is typing. With each new letter that is entered into the textbox, the dropdown list is refined.

Do I have it right?

If so, I did the same thing a while back, and I followed this excellent step-by-step tutorial:

How to Implement Autocomplete textbox in ASP.NET WITHOUT using Webservice & AJAX autocomplete extender.
