as per your question.... what i understood means validation is not working properly please check once your client side validations. if you have any error then it should be validate client side it will return false, then you wont go to the server side, you will not get that message.

Solution 1

With Response.Write you add a script tag (with your alert in it) just before anything else in your page, so it will be running before anything else (include actual rendering on the client)...
You have to render the script at the end - try ScriptManager[^]...
