I have an ordinary form with a post URL and runat server. Inside this form I have ordinary HTML fields but also a few ASP controls These ASP Controls are for a captcha I made, however when I press my captcha submit button then it submits the whole form rather than just the onClick code-behind event. I've tried using LinkButtons and so on rather than ordinary buttons to avoid it confusing the form but it still isn't working.
内部にあるフォームを投稿せずに、ポストバックとすべてで onClick イベントを作成する方法はありますか?
