Error: The parameter 'addresses' cannot be an empty string.
-
Hello The above is the error message I am getting followed by a long Stack Trace. I have a small form here http://www.dimadayoub.net/contact.aspx[^] and, to test it, I leave the email field blank on purpose (when I do the same for the other two fields, Name and Message, I get an on screen warning to complete the fields - which is what should happen). When I do the same with the email field, I get the above server error. The relevant code I have is this:
What should I be correcting, please?

Remove the
ValidationGroup="vgSubmit"attribute from both validators. Neither of your other validators have a validation group set, and neither does your submit button. Specifying Validation Groups | MSDN[^]

Many thanks, Richard, for your reply. I have done as you suggested and made a couple of other alterations. The code now looks like this:
The result is that when I complete the 3 fields correctly, the form is sent. When I complete the Name and Message fields, and Email field (without the @), I get an on screen error: 'Please complete the Email field' (for some reason it is in a white font and not the red of ="#FF6666"). I will amend that so it reads 'Please enter a valid email address'. When I leave the email field blank entirely (the form does not get sent, which is fine), but I can see a little asterisk. I presume that asterisk is this:
ErrorMessage="*"
Can I not replace that asterisk with the on screen message: 'Please complete the Email field'? Thanks again.

The
ErrorMessageis the message that gets displayed in theValidationSummary. TheTextis the message that gets displayed in-line. If you set theErrorMessagewithout setting theText, the same message is used in both places. You've usedDisplay="None", so the validators aren't showing up in-line. Instead, theValidationSummaryis showing all of the error messages next to the email field. You haven't applied any styles to theValidationSummary, which is why the messages are white. I'd be inclined to put a singleValidationSummaryat the top of your form. Then, for each validator, set theErrorMessageto the message you want to display, theTextto*, and theDisplaytoDynamic.

Thanks again. I think I am beginning to see what you mean - it will take some time for me to digest all your kind points. Yes, I can make those changes and see the results. Do you mean apply CSS to ValidationSummary1, and not RegularExpressionValidator2, in order to add style to 'Please complete the Email field'?

You need to add style to both - the style on the
ValidationSummarywill apply to the summary messages at the top of the form, and the style on the individual validators will apply to the "*" that appears next to an invalid field. I generally use a theme[^] folder with a.skinfile to apply the sameCssClassto all validators, and aCssClassto theValidationSummary. That way, the settings are consistent across the site, and the style settings remain in the CSS file where they belong. If you don't want to add a theme to your site, you'll need to set theCssClasson each validator andValidationSummarywherever you use them.

Yes, there is a theme to the site: www.dimadayoub.net[^], so the style would need to be consistent. Because space there is limited - the form is small - I was thinking of displaying the error messages in the form fields themselves. My CSS is not that good to do that - not sure it can be done in HTML/CSS alone. Grateful for your time.
