I have an asp.net page with a linkbutton. My form has two fields ("fname" and "lname") from which I would like to auto-generate an email address which is populated to the "email" field (example below). If the "fname" or "lname" (or both) is blank when the link button is clicked, an error should be displayed. I am using a code behind file and C#.
If this is not enough information, please let me know.
