Hi my friends, how r you

i asked to perform a calendar in a web site ..
the calendar may be simillar to the Calendar control of the ASP.NET , but i asked to put on it - beside every day- a comment got from a database .
i just want to know how can i edit the calendar class in C# or VB.NET or inherits it.
also is there is other way to do that? but in ASP.NET

it should look like the picture attached

Thanks
