Question

Is there any documentation on the parameters to WebForm_PostBackOptions? I can’t find anything by Googling.

Answer 1

There is no official documentation on this. However if you look at the javascript source code you will see this:

function WebForm_PostBackOptions(eventTarget, eventArgument, validation, validationGroup, actionUrl, trackFocus, clientSubmit) 

I think the parameter names are quite self-explanatory.
