How do I prevent double-clicking in ASP.NET MVC without using JavaScript?

I'm afraid without JavaScript there is no way to prevent this. If the click results in a POST request, then you can try to make it idempotent on the server side.

You cannot make sure the button is only clicked once, as you have no control over user's browser. What you can do, though, is to add a hidden field, a token to your forms so that if you see a token you've already seen, you'll be able to return an already-calculated answer.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
