How to generate _doPostBack even if no ASP.NET controls there?

Some of my aspx page have no controls on them, but I still want to wire some onclicks of html controls to the .NET 3.5 code using Request.Form["__EVENTTARGET"]. I've had this working great using this:


This way, even if there are no .NET controls on the page, the _doPostBack function gets generated by .NET then I can use it on my html pages like onclick="_doPostBack(this,args).

Now it the compiler is telling me Page.GetPostBackEventReference is obsolete and have to use Page.ClientScript.GetPostBackEventReference, but I don't know how to get it working the same way it was. It has different parameters with types I haven't used before, like PostBackOptions. Can someone help with this so I tell .NET to ALWAYS spit out the _doPostBack javascript function on the page no matter what?

I recommend also to read about IPostBackEventHandler, it's the interface that "listens" to _doPostBack().
