Our website needs to support browsers without Javascript. However, whenever a form is being submitted (using a normal submit button - not a link button), the error below is occurring...

This can be reproduced on the DotNetNuke forums by disabling Javascript in Firefox and attempting to search for any keyword.

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.

I won't go as far as to say you're having a brainless lapse, but you are most certainly mistaken. It is indeed possible to use asp.net controls with out javascipt. some controls, such as the linkbutton, and imagebutton, and datagrids do require javascript, but the textbox, buttons, dropdowns, etc do not require javascript at all.

Again, you are mistaken. It is completely possible to build a complete ASP.NET website, with postbacks and all, WITHOUT requiring JavaScript. Trust me on this. The problem I'm having is that DotNetNuke is throwing an error (see original post) when JavaScript is disabled in my browser, and my module performs a post-back. In my opinion this is a HUGE bug with DotNetNuke. I don't think DotNetNuke should require JavaScript to be enabled (although I can understand why it may be required for the 'admin' screens).  In fact, in my experience, this wasn't the case with 4.x versions of DotNetNuke. It's only happening in version 5.x. If JavaScript has only just become necessary in the lastest version of DotNetNuke I think this should be made abundantly clear to anyone considering using DNN as their CMS for any public facing websites. There are usability and accassbility concers to say the least with Javascript. Can ANYONE confirm whether JavaScript is a requirement for DNN and if NOT, how can I resolve the problem I'm encountering above?

Thank you.
