    Default Button

    I recently read an article that mentioned adding code to
    the onload event to "register a default button".

    The behavior i am after is that when the user hits enter,
    the form submits.

    Does anyone know how to do this using vb & asp.net?

    Thanks

      Default Button

      If you have a submit button on the form, when the user
      hits enter, it should submit the form

          Re: Default Button

          OK, but say that i have a login form where the button_click event runs
          code that calls a stored procedure. My form will not submit when I hit
          the enter key. Should i place the code in an "on_submit " event or
          something?

              When did the problem happen, when you hit Enter key in the Text box or on
              the submit button?

                  Luke,

                  The problem occurs when the textbox has focus. I have observed that a
                  typical behavior for users to to type in their usernams / password and
                  hit the Enter key. This leaves the focus on the textbox while the submit
                  is enacted.

                  I have tried capturing keystrokes from within the textbox but have not
                  been sucessful in doing so.

                  Thanks,

                  Michael
