Solution 1

Change your <%= (a response.Write expression) to <%# (a databinding expression), and see if that doesn't help.

If you want more info on the differences between the two, as well as additional variations, google is your friend.

Solution 2

If you have script tags like this:

<%= DateTime.Now %>

Replace them with DataBinding expressions instead. Like this:

<%# DateTime.Now %>
