Hello,
We have just migrated our 3.5 application to Framework 4. In one of our forms the update button was not firing the onclick event. We have found out the reason: if we have the "<" character with some other character, e.g.: "<b>", postback doesn't occur and we lose all the events (we didn't have any error or whatever). It seems that this characters are invalidating the viewstate or something like that (but that didn't happen in 3.5). We have ValidateRequest="false" in "pages" section in the web.config so I don't think it's because of the request validation.
Does anyone know if something has changed in the framework 4 to make this happen?
Thank you very much.
