Disable All

Disable All

I want to disable all the fields on the form when it loads.  I know there is a way to do this by listing all the fields as follows:

disable Name;
disable Address;
disable City; 
...

I have over 50 fields on my form and i am wondering if there is a single command or way to just disable all fields on load.  

On load = disable All

Thank you for any help.
