I have two WebDataChooser controls:
1. Start Date
2. End Date
Now, I want some client side validation to ensure that my end date is not earlier than my start date. How do I do this? Is there any support for ASP.NET Validators (or at least free validators). Otherwise can you suggest any other solution?
Hi, You can use a requiredfield validator and some client-side code.
Here is a small crude page i put together to validate the start and end dates
