Short answer is No. However you can leave the page_load method blank.

You probably want to use IsPostBack flag in Page_Load

No.
When your user presses a button, it starts an instance of your application on the server and automatically executes the page_load event.

Instead, use IsPostBack to prevent the page load event changing user data - when the used presses a button it will be set to true.

It depend on your code that you written on the button click event, If you do not want to postback the page then I suggest you to use jQuery Ajax from the following LINK. In this technique postback not happen and hence only your button click code will work.
hope this help you

I have to say, you can do it. why don't you rethink on the desired behavior and redesign your strategy.

Although, If your button click event is not dependent on any other control of the page and is not using any other values from the page, you can disable the postback and move the code of button into other page that can be called using XMLhttpRequest. (perhaps that not what you are looking for)

Use PageMethod to avoid full page life cycle. It will directly hit a method in the code behind.
Here: PageMethod[^]
