Having angular braces "<" with in a text box, hidden field, text area, etc., triggers this error during server post. ASP.NET engine thinks that malicious code has been injected into the request stream and stops processing the request and raises this error, when it encounters such a situation. To over come this, either replace the angular braces with their HTML code "<" - & l t ; ">" - & g t ; [with out the spaces] or else set
ValidateRequest="false"on the page directive of the page. This web page has examples for both solutions Allowing HTML Formatted User Input in ASP.NET [^] NOTE: The later would make your page susceptible to injection attacks. -
