[thelist] ASP.NET CompareValidator Control

Mon Oct 10 11:29:40 CDT 2005

All

I have created a CompareValidator control in ASP.NET that simply
validates the content of two text boxes. It works as I expect when
EnableClientScript is set to "false", but when set to "true" the
validation fires when either of the text fields to be validated are
given focus (or clicked on - I cannot tell which). Can anyone explain to
me what I'm doing wrong? All the examples I have found on the web have
EnableClientScript set to "false", but with no explanation why. As I
understood it, setting this attribute to "true" should give client-side
validation where available.

The code is as follows. Thanks in advance (as always) for any
assistance.
