Have you tried using Server.HTMLEncode() on the contents of the textbox? — SoftwareGeek

You could probably add some javascript to encode the textbox value before the form is submitted.

something like:

$(function() {
  $("form").submit(function() {
    var myTextBox = $("#myTextBox");
    myTextBox.val( encodeMyHtml( myTextBox.val() ) );
  });
});

function encodeMyHtml(encodedHtml) {
  encodedHtml = escape(encodedHtml);
  encodedHtml = encodedHtml.replace(/\//g,"%2F");
  encodedHtml = encodedHtml.replace(/\?/g,"%3F");
  encodedHtml = encodedHtml.replace(/=/g,"%3D");
  encodedHtml = encodedHtml.replace(/&/g,"%26");
  encodedHtml = encodedHtml.replace(/@/g,"%40");
  encodeHtml.htmlEncoded.value = encodedHtml;
}

I should add that the user will probably see the value of the textbox change into the encoded value while the form is submitting.

Control.ValidateRequestMode, new to .NET 4.5, might be of interest to you. It allows you to specify how individual controls are validated.
