Explanation

As you can see in above code snippet, we have three buttons as btnGo1, btnGo2, btnGo3.

Now say we like to make btnGo2 as default button.

We created a panel and declare the default button Id and put the remaining code inside the pannel.

So now btnGo2 is the default for your page. You can change it by assigning other button Id inside pannel tag.
