ASPX site can't detect form fields filled in by JavaScript
<p>I'm working on a web application in ASP.NET/C#, which involves asking users to input data. My client has requested the addition of a JavaScript utility that allows the user to enter a postcode, and have all other address fields be automatically filled in for them. When we test the application, the JavaScript appears to fill in the address fields correctly but the C# validation code reports them to be empty. I've tried googling several different combinations of terms but haven't found anything useful. How do I get this to work?</p>
