William,

I think possibly the problem is that you're not specifically sending a string to your IsDate method. Try using:

if (!IsDate(e.Value.ToString()))

I don't have much WebForm experience, so if this isn't the problem, I probably don't have too many other suggestions, but give that a try and see if it helps.
