Validation Control in Materpage\Conentpage\ContentPlaceHolder

J

REFERENCE: Masterpage Master Page Conentpage Content Page ContentPlaceHolder Validation
Control

I have a Masterpage\Contentpage with no errors shown in VS2008 but the VALIDATION
control in the Contentpage doesn't fire. I have put the Contentpage in a "regular" aspx
page (no Masterpage) and the VALIDATION control works. It just never fires in the
Masterpage\Contentpage scenerio.

If I leave the textbox empty the validation control should fire. Why doesn't it.

Thanks

As it turns out, I had a bunch of HTML (controls and validators) that were commented out
at the BOTTOM of the Contentpage (<%-- bunch of stuff --%>). For whatever reason, the
commented out stuff was preventing the validation controls from firing. Once I removed
those lines, the validation controls fire for all controls. Apparently somewhere along
the internal MS parsing, I presume those commented out controls and validators were
scrambling the system's "brains".
