I continue doing testing to solve my issue, I've changed to selenium firefox, and I've tried to wait load the page but doesn't work, but I'm seeing on firebox the id that I'm trying to find on selenium, but selenium could no find it. I don't know if I'm doing something bad or there is some bug.
Furthermore, I post two screenshots if someone occurs something
There is one detail on exception, the id selenium can't find is #ContentPlaceHolder1_Objeto_FormPanel\-innerCt , but the right id set in code is ContentPlaceHolder1_Objeto_FormPanel-innerCt, the exception element adds character "\"
