Designer code problem

Hi.  I'm new to VS2008, and I am finding something rather annoying.  If I have a form, say Form1.cs, I wanted to make a textbox control on the form do something when double clicked.  I double clicked the textbox in the design mode and it created a "textchanged" event...  not what I wanted.  So I figured I'd just add the eventhandler manually.  I expanded Form1.cs in the solution explorer and right clicked Form1.Designer.cs and hit View Code.  What I got though didn't have the control creation code.  I thought OK, that's weird. 

I went and deleted the textbox1_TextChanged function it created then did a build to cause it to trip a fault.  When I double clicked the fault, it opened Form1.Designer.cs code and there was all the code I was looking for.  I made the change, saved it, closed it.  Right clicked it again, View Code, there it all is.  Cool.

Now several minutes later I right clicked it, View Code, and I'm back to the basic short code list w/o the controls.  WTF???  Augh this is annoying.
