    Having an issue with trying to handle the < character in a RadTextBox. I didn't want to have to resort to putting a RadEditor on the form as no other formatting is required.


    The exception happens on your RadTextbox demo form, as seen in the attachment.


    Can this be handled elegantly w/o blowing up the page?

    Hi Mike,

    This is an ASP.NET form submit validation mechanism so you'll experience the same error even if you replace RadTextBox with a regular asp:TextBox

    A potentially dangerous Request.Form value was detected from the client (TextBox3_ClientState="...ionText":"<span","valueAsStrin...").

    The solution is to:
