Hi

I'm trying to add a RegularExpressionValidator to textboxes in a web page to 
stop users entering invalid hmtl tags without much success.

For example,  if a user enters <b/> into the textbox, on postback the page 
errors without me being able to trap the error.

I'm sure there is a simple solution to this but I've spent hours trying to 
find the answer.

Can anyone help please?

TIA

Richard
