Hi there,

I just updated an app from .net 2.0 to .net 4.0 and i have noticed the following...

For example i have the following control..

 <input type="hidden" name="ctl00$cphMain$hfdFueraHorarioOficinaConfirmado" 
 id="cphMain_hfdFueraHorarioOficinaConfirmado" value="False" />

and then in javascript i did this before..

 var hfdFueraHorarioOficinaConfirmado=document.getElementById('ctl00_cphMain_hfdFueraHorarioOficinaConfirmado');

but after checking the Id within the html source once it renders and also doing some debugging with firebug etc....

it has changed from

  ctl00_cphMain_hfdFueraHorarioOficinaConfirmado

to

  cphMain_hfdFueraHorarioOficinaConfirmado

can anyone explain why? .... so should i basically do a search and replace and remove the ctl00??????

A little confused

Obviosuly the javascript line with the the ctl00_ infront return NULL because it doesn't exist, but removing this returns the object..

Any help or ideas really appreciated

Thanks
