Unfortunately, I couldn't replicate the RadTabStrip input issue with iOS7 iPad. I have tested a simple RadTabStrip scenario and I tried both Safari and Chrome browsers. On my side the input is unselectable, unless I explicitly change its type attribute from "hidden" to "visible".
Just to double check that you are referring RadTabStrip control, you can find RadTabStrip demos and their source code here
In order to assist you in the most efficient way I would kindly suggest that you provide a very simplified runnable project that demonstrates the behavior that you describe. Thus we could test it locally and determine what might be causing the issue that you are experiencing.
Thank you in advance for your cooperation.
