angularjs - angular validation within ng-repeat -


i have below validation texboxes within ng-repeat

<div class="col-md-6 col-lg-2">     <div class="form-group">         <label for="country{{$index}}" class="control-label required">country</label>         <div class="input-group">             <mc-lookup-dropdown data-lookup-name="countrytype" required data-model="contactaddress.country" id="country{{$index}}" name="country{{$index}}" class="form-control"></mc-lookup-dropdown>         </div>         <div data-ng-messages="memberdemographics.demographics.$error" class="validation-errors">             <div data-ng-message="country">{{ contactaddress.$servererrors.country }}</div></div>         <div data-ng-messages="demographicsform.{{'country'+$index}}.$error" class="validation-errors">             <div data-ng-message="required" data-ng-show="!demographicsform.{{'country'+$index}}.$pristine">this field required</div>         </div>     </div> </div>

below error thrown on pageload "rror: [$parse:syntax]

http://errors.angularjs.org/1.5.8/$parse/syntax?p0=%7b&p1=is%20not%20a%20validnandentifier&p2=18&p3=demographicsform.%7b%7b'phonenumber'%2b%index%7d%7d.%24error&p4=%7b%7b'phonenumber'%2b%index%7d%7d.%24error"

i need have expression in ng-message since textname depends on $index of ng-repeat loop..

these lines having errors:

<div data-ng-messages="demographicsform.{{'country'+$index}}.$error" class="validation-errors"> <div data-ng-message="required" data-ng-show="!demographicsform.{{'country'+$index}}.$pristine">this field required</div>

change : 

<div data-ng-messages="demographicsform['country' + $index].$error" class="validation-errors"> <div data-ng-message="required" data-ng-show="!demographicsform['country'+$index].$pristine">this field required</div>

from this article

you need wrap in braces when using angular's templating system - braces tell angular replace value. in case, value of data-ng-message expression being evaluated.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
