Another possibility is that Visual Studio browser link is enabled. To figure out what caused the issue you can inspect the Request object.

Do you have any controls with AutoPostBack set to true ? That will cause the Page object to be recreated and therefore the PageLoad method will execute again.

Make sure you don't have any tags like <img src="#"> or <img src="">, that makes IIS load the page twice. It's a classic.

Do you have AutoEventWireUp set to true and also attaching an event handler in code? This is a common reason.
