Pressing the Enter key on an ASP.NET form doesn't necessarily cause a form submission. To force a particular button on the page to fire and cause a postback on Enter, simply add one line of code:

Page.RegisterHiddenField("__EVENTTARGET", "BUTTON_NAME")

Change BUTTON_NAME to the ID of the button to which you want to default. This trick is limited by certain controls in HTML, such as a multiline textbox in which the default action is to create a new line.

Siva,

I cannot get this code to work. I placed it in the page load event. Is that not the right place.

Page.RegisterHiddenField("__EVENTTARGET", "btnMyButton")

I also imported the System.Web.UI namespace

Its the right place to put the code. Put it with a little modification
Page.RegisterHiddenField( "__EVENTTARGET", yourButton.ClientID);
