You say that these buttons exist in a web page. Web page events happen at a particular time in the page load life cycle.

When you submit a form, the page is loaded and then the events take place. This means that you will only submit the form once with each button.

You can get around this by using update panels which would post back the form without reloading it.

The post back event do occur as events so each will run on a separate thread anyway. The only way that you would hit this problem is if you have a shared resource such as a static field.

If you are experiencing a specific issue then reply with the details of that problem and I will investigate further

Hope that helps ^_^
