How to submit a form using the Enter key in asp.net

I have 3 buttons in a form. One of them is the submit button. How can I make it the default button to be clicked when I press the enter key. Is there a property for this?

From stackoverflow

• There is a property for the form: defaultbutton.

  <form runat="server" defaultbutton="myButton">
  ...
  </form>
  

  It is first time implemented in ASP.NET 2.0.

• Or you can do it in code - Page_load:
  

  Page.Form.DefaultButton = btnSearch.UniqueID;
  

  Whenever you press enter the btnSerach control will be used as default.

• Another helpful tip is that you can set the default button on asp:panel's too.
