Setting the Default Button in ASP.Net 1.1
A: In ASP.Net the enter button executes the first button on the page. So create a button that is not visible (width is set to 1 px) and placed it at the top of the page before the logoff button. Change the background color if needed and make sure it cannot be seen. Then set the click event in .aspx page to execute the search button click event. When the user presses enter, the first button is executed and it will call the search method.
