In ASP.NET using Visual Studio 2005 or Visual

The use of Up
Down Extender it that you are not require to type any number of character you
have to just select from the up down button…it will change dynamically when you

To follow this code sample, you must use Visual Studio 2005 or Visual Studio

Note: Up
Down Extender is a part of
AjaxControlToolkit.
To attach right click on the toolbox under Ajax Extensions and select
Choose Items - > Browse Button - > select the AjaxControlToolkit.dll. If
you are using Visual Studio 2008, you may not need AJAX Toolkit but if you are
using Visual Studio 2005, you will need to download it from http://www.msdn.com/ or http://www.asp.net/.
Step 1. Start -> All Programs -> Visual Studio 2005
or Visual Studio 2008

path by the browse button - > Choose the language from the Language ComboBox
(Visual C# , Visual Basic , J #)
