Plum Blossom Rain Calendar control is not available under the asp.net2.0 solution

Asp.net| Resolution | control | calendar

Plum Blossom Rain Calendar control is really good, but in ASP.net 2.0, will find an old way to use, JS error "missing object."
The workaround is as follows

1, <%@ Page language= "C #" codepage= "936" ...
Be sure to add 936 or else make an error
2, remove
<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
This line

The problem is solved, but it feels like doing so will affect the internationalization of the Web site and may lead to the loss of standardized XHTML!
