title: textbox with textchanged event firing
body: <p>I have two textboxes with textchanged events.  When I enter characters in first textbox and press enter, the textbox1_textchanged event is fired.  Then I enter some characters in the second textbox and press enter, the textbox2_textchanged event fires as well.  However, when I move my cursor in first text box without changing any characters and pressed enter, the events won't fire for both textboxes.</p>
  
  <p>I want the respective textbox events to fire without changing any characters in textboxes.
  If I press enter with some characters in textbox1/textbox2 its txt_changed events have to fire.</p>
  
  <p>I have tried, but if I enter characters in textbox2 first the textbox1_textchanged get fired.
  Any help? </p>
