asp.net - page reloaded aginst my will

Ajax tutorial[^]

See my previous answer on this

Preventing postback[^]

You can 'prevent postback' so the buttons do not call back to the server.

If that's what you want, you'll need to run some sort of client side functionality to do something when you click the button, normally some javascript.

Otherwise, if you want server side code to run, just ignore the postbacks in your Page_Load event - you can write code like

if (!Page.IsPostBack)
{
    // Do something here that only happens the first time the page loads
}

Then, just create event handlers for your buttons and write code accordingly.

What approach you should use depends entirely on what you're trying to achieve
