I am creating a web app in which i am using c# with angularjs currently i am updating my records in which i have one dropdownlist called zone which looks like this
Solution 1:
Hello you can take a look at ngOption:
https://docs.angularjs.org/api/ng/directive/ngOptions
Solution 2:
Try this :
<select ng-model="uzone" ng-change="locationupd(c)">
<option ng-repeat="l in gzone" ng-value="l.jzone">{{l.jzone}}</option>
</select>
Copy
Solution 3:
use a $scope variable to select the option first.
in my case i have $scope.opt = $scope.items[0];
angular
.module("myModule", [])
.controller("myController", ['$scope', function ($scope) {
$scope.items = [{id: 1,label: 'aLabel'}, {id: 2,label: 'bLabel'},{id: 3,label: 'cLabel'}, {id: 4,label: 'dLabel'}, {id: 5,label: 'eLabel'}, {id: 6,label: 'fLabel'}, {id: 7,label: 'gLabel'}];
$scope.opt = $scope.items[0];
}]);Copy
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="myModule" >
<div ng-controller="myController">
<select ng-model="opt" ng-options="i as i.label for i in items track by i.id ">
<option value="">Select ALL</option>
</select><br />
</div>
</body>Copy

I dealt with a similar situation yesterday at work.
My drop down list had to list the names of all countries.
I am now able to set a default value for the drop down list.
Please change the code according to your needs.
What I had to do: Set CH/Switzerland as default value for vm.selectedCountry.
CodePen code (using select):
Sample:
<select class="selector" ng-model="vm.selectedCountry" ng-options="country.name for country in vm.countries" ng-init="vm.selectedCountry = {'name': 'Switzerland', 'code': 'CH', 'init': true}">
<!--shows only when ng-init is run-->
<option value="" ng-show="vm.selectedCountry.init">Switzerland</option>
</select>

CodePen code (using md-select and Angular Material):
Sample:
<md-select ng-model="vm.selectedCountry" ng-init="vm.selectedCountry = vm.selectedCountry?selectedCountry : 'CH';">
<md-option ng-value="'CH'" ng-selected="vm.selectedCountry == 'CH'?true:false">Switzerland</md-option>
<md-option ng-repeat="country in vm.countries" ng-value="country.code">
{{country.name}}
</md-option>
</md-select>

In the above one, the default value is spliced from the array and put first in md-select (else, duplication occurs).
