Where Can I Find Key Events in LightSwitch? -

i'm working on project in lightswitch , i'm trying handle keyup event on specific screen

i couldn't find it, can find events (such keyup keydown lostfocus ext. )

and if not supported should handle situation that?

i guess referring controls , not actual screen. so, example, handle keyboard events on textbox, 1 way of achieving in example, have "address1" textbox , want change text whenever user types letter:
1 - on activated event of screen, can required textbox:

partial void customerslistdetail_activated() {     this.findcontrol("address1").controlavailable += addresstextboxavailable; } 

2 - on available event handler, can connect required event (you can have keyup, keydown, lostfocus , others):

private void addresstextboxavailable(object sender, controlavailableeventargs e) {     ((system.windows.controls.textbox) e.control).keyup += addresstextboxkeyup; } 

3 - on keyup event handler, can manipulation:

private void addresstextboxkeyup(object sender, keyeventargs e) {     if (e.key == key.a)     {         ((system.windows.controls.textbox) sender).text = "you typed a";     } }
