SubmitForm vs MailDoc

Question: How can I validate the required fields as well as send the customized email?

Answer: You can submit to a server-side script using a normal submit button which validates the required fields and emails the form submission without client side email software. ASP.net scripts can parse the submission data using iText technologies and customize the to, cc, bcc, subject, body and attachment file name.

The required field property and submit work for web pages but not user friendly. It is better to write a custom script to validate that the required fields are completed and provide a more user friendly interaction.

You can write a custom JavaScript button that checks the required fields are completed before carrying out the submit action or not.

Custom JavaScript requires you put the various JavaScript statements to perform the process you want done. You can read each field and test the "Required" property. If it is a required field, you can then compare the default value and the value of the field. If they are equal, then the form field has not been completed and you need to keep track of this fact.

There have been many questions and replies about this topic. You can use the search feature of this site to find them.

You'll need to perform the validation yourself, using a script.

Over the years I posted the code that does that many times on these forums... Search for "required fields validation" and you'll find it for sure.
