I'm completely stumped trying to solve this puzzle...
In my ASP.NET web form, I have dynamically generated form fields. Based on the selection in a dropdown list, the visibility of a specific textbox changes. This is achieved using client-side scripting.
My goal is for users to choose "Other" from the dropdown list, causing the "Other Description" field to display on the form. I want to include a requiredfield validator or some kind of validation for this textbox when it becomes visible.
Do you have any ideas on how I can make this happen? I've ruled out using postbacks in my testing since the form field needs to be present for an empty value. (Unfortunately, this code was passed down to me by another developer)
