Please suggest me: I need to show validation only if some text is entered in between < and >. Rest of the cases should be accepted by the browser. Suggest a solution without security concern. – Sachin Feb 23 '16 at 10:31

Such symbols are forbidden for security reasons - otherwise someone can simply inject their code. If you need to pass such symbols you should pass them like this : "/<" "/>"
Or Set TextBox attribute ValidateRequestMode = ValidateRequestMode.Disabled

If you want to allow HTML tags i.e "<>" then you need to set validateRequest="false" in ASP pages , best thing is to parse those tags using HTML encoder .

the drawback is that , security get's compromised , you should use asp.net "Antixss" or create your own text parser to avoid user entering malicious links and javascript code along with data , google for javascript libraries – Rakesh Bk Feb 19 '16 at 12:47
