How to safely allow html input in texboxes?

[DDK]

I am trying to figure out the best way to allow users to submit HTML in a
textbox, and allow them the ability to edit the text HTML submitted
afterwards safely in ASP.NET + C# (submitted to a sql server database), so
that the application is not subject to script attacks. Any ideas on the best
options for this.

thanks,
d.

You could use a regular expression validator to allow certain limited
characters, and not others.
