Error creating Regular Expression Validator control
(OP)
Happy Friday, colleagues!
Not so happy for yours truly...
Subject line says what the problem I have. Here's the code (exactly as in the book "Murach's ASP.NET 4.6 Web Programming with C# 2015", pg. 271, fig. 7-13):
Let alone it's hard not to screw up typing this expression (in bold, red), but VS tells me... well, picture (Design screen) worth 1K words:
I check all chars in this regex 3 times - exact match to the one in the book, so...
Where do I err?
Please advise!
AHWBGA!

\w([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.])\w+)*
RE: Error creating Regular Expression Validator control
It turns out that it's a typo in the book. I added this opening parenthesis in front - and it worked.
Thank you!
