I have a textbox containing a date in the format “dd.MM.yyyy”. Now I want to use a RegularExpressionValidator to see if the format matches “digit digit . digit digit . digit digit digit digit” (without spaces)
How does the regular expression look like for this?
Well, the regex
"\d{2}\.\d{2}\.\d{4}"should work – but it won’t validate that the values are sensible. For example, it will allow “55.66.3000”.
