I got this problem:
'WebForm_PostBackOptions' is undefined
javascript error when i have an asp:linkbutton in a page. Replace it with a asp:button and all is cool after school. I have trawled the net without out trolling the net but to no avail. Just a bunch of peeps asking the same damned queston. Im super duper hopin the stack overflowers can once and for all solve this nasty ol' issue so we can be done with it forever and good. Thanks.
