asp.net imposes this checking to avoid script injections.But you can override this by changing the validateRequest property value to "false" in page directive

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="editpage.aspx.cs" validateRequest="false" Inherits="MyProject.UI.editpage" %>

You can try adding the validaterequest=false attribute, but I would not recommend doing this. Encode/decode the HTML instead.
