asp.net - WebForm_PostBackOptions documentation -

Is there a document on the parameters of WebForm_PostBackOptions? I can not get anything by googling

There is no official document on this. However, if you look at the Javascript source code you will see:

  function WebForm_PostBackOptions (eventTarget, eventArgument, verification, verification group, action URL, track focus, client submit)  < / Pre> 
 I think the parameter name is quite self explanatory.
