To make this work you need to do the follow.
1. Create a Folder under your IIS directory (the default directory format that IIS installs to is C:\Inetpub\wwwroot\)
2. Open Administrative tools (Start Menu --> Control Panel --> Administrative Tools)
3. Expand the Website branch to open up the IIS folder structure. Keep drilling down till you see your newly created folder.
4. Right Click your folder, and select
Properties
5. In the properties window, and on the
Directory Tab there is a section called
application settings and a button called
create. Click the CREATE button and then click OK.
6. Create your aspx file with this calendar control in the code (as you have already done), save it to the new folder you just created and then open the file by typing in the browers address bar (or even the start menu --> run command)
http://localhost/your directory name you just created/then the name of the aspx file name & extension Voila!
Hope this helps!
