Hi Lokesh,
Try using ng-options.
assuming your 'PropCollection' is an array of form:
$scope.PropCollection = [{"ViewerName":"AbhiNAV5"},{"ViewerName":"RaviNATH6"}];
under your js file (or tag)
mention the following
$scope.viewName = PropCollection[0].ViewerName;
and try building html like this
<select ng-model="viewName" ng-options="view.ViewName for view in PropCollection">
</select>
Now you can access the selected value using
"viewName".
For dropdowns you have a predefined directive called ng-options.
See this plnkr for reference.
