Install AjaxControlToolkit for VS 2008

Install AjaxControlToolkit for VS 2008
I am crying to develop ASP.NET using VS 2008 because that have limited control.
after download ajaxcontrol from http://asp.net I am happy because i get control for development.
1. Download for framework 3.5 ajaxcontrol from http://asp.net
2. Extract this file to C:\Program Files\Microsoft ASP.NET Ajax Extention.
3. Open your Visual Studio 2008.
4. Add tab in your toolbox and give toolbox name "AJAX Toolkits".
5. Choose Item and browse to your folder.
example : "C:\Program Files\Microsoft ASP.NET Ajax Extention\SampleWebSite\Bin\AjaxControlToolkit.dll"
6. Now you can see new component in "AJAX Toolkits"

Now you can use new component for your web application like datepicker, cascading dropdwon and more.
dot forget use this tag in your code.

Example using Calender Extender:

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>

<ajaxToolkit:ToolkitScriptManager runat="Server" EnableScriptGlobalization="true" EnableScriptLocalization="true" ID="ScriptManager1" />

<asp:TextBox ID="TxtUntil" runat="server" MaxLength="10" Width="80px"></asp:TextBox>
<asp:ImageButton ID="ImgUntil" runat="server" ImageUrl="~/images/Calendar_scheduleHS.png" AlternateText="Click to show calendar" />
<ajaxToolkit:CalendarExtender ID="CalExUntil" Format="dd-MM-yyyy" runat="server" PopupButtonID="ImgUntil" TargetControlID="TxtUntil"> </ajaxToolkit:CalendarExtender>
