Return key behavior

I've got an ASP.NET gridview that I've modified by causing an "insert" row to appear in the middle of it.  The insert row has one text input field (and variations may have several).   This is all done in javascript.    I don't think the ASP.NET aspect matters but I thought I would describe it to be clear.

What I now need to know is how I might control the return key behavior in this situation.  I'd like the return key to do nothing if the focus is on the text fields.  Then, when the focus is on an <img> that I'm using as an "enter" key, I'd like the enter key to essentially "press the button" (or fire the associated function).

Any guidance on this would be appreciated.

Thanks!

When you specify each field that you want to 'tab' between, give each field a tab index, and use the DOM to select the next field if the enter key is pressed.  If you want a field or object to be skipped when tabbing, give it a value of "-1"

<input type="textfield" name="myfiels" id="myfield" tabindex="1" onkey="return enter(document.formename.nextfieldyouwant)"

The javascript enter() function I use is:

   function enter(nextfield) {
           if(window.event && window.event.keyCode == 13) {
                   nextfield.focus();
                   return false;
           } else {
                   return true;
           }
   }

I also use a no enter() function to make sure that somebody can press the <enter> key when writing in a text area without submitting the form:

function noenter() {
  return !(window.event && window.event.keyCode == 13);
}

<textarea name="comment" ...  onKeyPress="return noenter()" >Enter somtext in this text area..</textarea>
