Many people using blank rules in C# code, use the following commands:

var brControl1 = new HtmlGenericControl { InnerHtml = "<br />" };
var brControl2 = new HtmlGenericControl("br");

However, brControl1 also prints a <span> tag and brControl2 prints <br></br>. Both options are not really useful. You should take notice of the fact that the HtmlGenericControl is not meant to be used for anything else than span, body, div and font (what is designed for ‘as the word goes’).  The way to go when printing a blank rule is:

var brControl3 = new LiteralControl("<br />");

This actually prints exactly what you would like it to print, namely <br />. Hope this helps you too ! BTW, if you are using the HtmlTextWriter class, you can also use the WriteBreak() function if you like.

Luckily, at the end of the day, I discovered DD_roundies, a Javascript library perfectly taking care of my needs. Only in Opera this functionality does not function as wanted (no rounded corners), but that’s an issue Drew Diller is trying to address, according to his website. I definitely would suggest you to try for yourself if you would like an acceptable solution to the problem described hereabove.

The only thing that does not currently stop bothering me: unfortunately it is (still) not possible to have some javascript in an ASP.NET theme. Would that be possible, the solution would be perfect (for me). Perhaps somebody found a solution for me ?
