♣ By default ASP.Net tool box window will come with 5 AJAX controls
♣ If you want to add remaining AJAX controls we have to add AJAX controls tool kit explicitly to ASP.net tool box window.
♣ We can download the AJAX control tool kit from the below website
♣ When we will visit the above website we can identify a link called “AJAX controls tool kit Source code”.
♣ When we will double click on the above link it will download a ZIP format file
♣ When we extracted the ZIP format file, it will produce a visual studio .net project folder
♣ Now open that visual studio .net project and build, with this process it will produce a dll file with in the project debug folder like below
AJAX control tool kit.dll
♣ This dll is nothing but AJAX control tool kit
