ASP.NET Find Control with only part of the UniqueID

So I have a situation where we are trying to reduce the page size. My job is to remove as much of the uniqueID's in the markup as possible.

This is where I'm having a problem: I have a value which is "innerContent$wizard$myTextBox" and its UniqueID is ctl00$ctl00$content$innerContent$wizard$myTextBox. I have a call on the page page.FindControl(value) which returns null because I only have half the UniqueID

So my question is: How can I use FindC开发者_如何学Control() with only half the UniqueID? I'm certain that the value is unique for the page. (i.e there is no other UniqueID ending with this value.)

Which half do you get?

If you are using asp.net 4.0, set the ClientIDMode="Static"

Here is another one that talks about Predictable, but briefly goes over others

Why do you have to use the Page's find control method? Usually you would use the findcontrol method of the parent control or naming contained and pass the Id in the mark up rather than the uniqueId.
