How to Select a Single Row with ui-grid?

Question

I'm working with university project. I have working REST API with spring boot and a angularJs front end. this is my working part of the angularJs.

HomeService.js

this.getDeviceList = function getDeviceList(){
    return $http.get(REST_SERVICE_URI + '/get_device_list')

}

 this.getPeripheralList = function getPeripheralList(dev_hard_id){
    return $http.get(REST_SERVICE_URI + '/get_peripherals/?dev_hard_id=' + dev_hard_id)
}

Working functions in HomeController.js

$scope.getDeviceList = function () {
    HomeService.getDeviceList()
      .then (function success(response){ 
          $scope.details = response.data;
          $scope.errorMessage = '';
      },

      function error(response){
          $scope.errorMessage = 'Error occured!!!';
          $scope.message = response.data.message;
    });
}

$scope.getPeripheralList = function (devHardwareId){
    HomeService.getPeripheralList(devHardwareId)
    .then (function success(response){
        $scope.peripheralDetails = response.data;
        $scope.errorMessage = '';
    },
    function error(response) {
        $scope.errorMessage = 'Error occured!!!';
        $scope.message = response.data.message;

    });
}

the working primitive table in html file.

<div class="panel-heading">
                Logged in user: <b th:inline="text"> [[${#httpServletRequest.remoteUser}]] </b>
                <br>
                <span class="lead">Devices</span></div>
                <div class="panel-body">

                    <div class="table-responsive">
                        <table class="table table-hover">
                                <thead>
                                        <tr>
                                            <th>Device Name</th>

                                        </tr>
                                </thead>
                                <tbody>
                                        <tr ng-repeat="d in details track by d.devHardwareId">
                                            <td>{{d.deviceName}}</td>

                                            <td align="right"><button type="button" ng-click="getPeripheralList(d.devHardwareId)" class="btn btn-success custom-width">Attached Devices</button></td>
                                        </tr>
                                </tbody>
                        </table>      
                    </div>
                </div>

above codes are working well. but my requirement is I need to select a single row and at the time I need to call getPeripheralList(d.devHardwareId) function for the particular device. for that I'm using ui-grid.

so I've added functions in my HomeController.js

$scope.gridOptions = { enableRowSelection: true, enableRowHeaderSelection: false };

$scope.gridOptions.columnDefs = [
    { name: 'Device HardwareId' },
    { name: 'Device Name'},
    { name: 'Device Ip Address'},
    { name: 'Attached Cameras' }
  ];

$scope.gridOptions.multiSelect = false;
$scope.gridOptions.modifierKeysToMultiSelect = false;
$scope.gridOptions.noUnselect = true;
$scope.gridOptions.onRegisterApi = function( gridApi ) {
$scope.gridApi = gridApi;
  };


$scope.toggleRowSelection = function() {
    $scope.gridApi.selection.clearSelectedRows();
    $scope.gridOptions.enableRowSelection = !$scope.gridOptions.enableRowSelection;
    $scope.gridApi.core.notifyDataChange( uiGridConstants.dataChange.OPTIONS);
  };

$scope.deviceGrid = {
    data: 'details',
};

and have changed html page too..

<button type="button" class="btn btn-success" ng-click="toggleRowSelection()">Toggle rowSelection</button>
<strong>rowSelection:</strong> 
<span ng-bind="gridApi.grid.options.enableRowSelection"></span>
<div ui-grid="deviceGrid" ui-grid-selection class="grid"></div>

but this doesn't work as I expect. it allow to select multiple rows which I don't wanna do and I don't understand how to call the getPeripheralList(d.devHardwareId) function with the ui-grid. (whenever I select a single row I wanna call above method) so I wish to get help from someone here.

If you dont want to allow selecting multiple rows in your grid you only have to configure it in your gridOptions just like this:

$scope.gridOptions = { enableRowSelection: true, enableRowHeaderSelection: false, multiSelect:false };

If you want to call a function when a row is selected you have to register gridApi and use it, you could do something like the following:

$scope.gridOptions = { enableRowSelection: true, enableRowHeaderSelection: false, multiSelect:false, 
onRegisterApi: function (gridApi) { 
 gridApi.selection.on.rowSelectionChanged($scope, function (row) {
     // Your call to your function goes here
    });
}};

How can I rename and filter some fields from the database? – Tharuka Feb 26 '18 at 09:40
Ui-grid has some built-in filters, [filtering tutorial](http://ui-grid.info/docs/#!/tutorial/103_filtering). But it allows you creating your own filter functions. Maybe you should take a look to the documentation for ui-grid. Hope it helps! – A1t0r Feb 26 '18 at 11:22

This was the answer

$scope.deviceGrid = { 
data:'details',
enableRowSelection: true, 
enableRowHeaderSelection: false, 
enableSelectAll: false,
multiSelect: false,
noUnselect: true,
onRegisterApi: function (gridApi) { 
 gridApi.selection.on.rowSelectionChanged($scope, function (row) {
    var msg = 'row selected ' + row.isSelected;
   console.log(row.entity.devHardwareId);
   HomeService.getPeripheralList(row.entity.devHardwareId).then (function success(response){
    $scope.peripheralDetails = response.data;
    $scope.errorMessage = '';
},
function error(response) {
    $scope.errorMessage = 'Error occured!!!';
    $scope.message = response.data.message;

});
    });
}};
