This problem will arise due to 2 reasons

1. If you have old Ajax Toolkit installed already installed and if you try to have a new version again, the old js files will be used. This might cause the error. Remove both versions, delete all the files from program files and install again.

2. You would've created the project type as asp.net project and not ajax enabled asp.net project.

hi,

1. plz provide the steps from ground up for installing new ajax tool kit by deleting the old one....

2. i have created the project as ajax enabled asp.net web site, but still not works...

thanks,
