Local Data

To set the local JSON data, define a JSON array and initialize the GroupButton with dataSource property. Specify the column names in the fields’ property.

NOTE

the columns are bounded automatically when the field’s are specified with the default names like id, text, etc…

Below is the sample to code to render the GroupButton JSON dataSource.

  • html
  • <div id="groupButton" ej-groupbutton e-groupbuttonmode="radiobutton" e-width="100%" e-showroundedcorner="true" e-datasource="dataSource"></div>
  • js
  • <script>
            angular.module('GroupBtnCtrl', ['ejangular'])
            .controller('GroupBtnCtller', function ($scope) {
                
                var groupdata = [
                            { text: "Day", contentType: "textonly" },
                            { text: "Week", contentType: "textonly" },
                            { text: "Work Week", contentType: "textonly" },
                            { text: "Month", contentType: "textonly", selected: "selected" },
                            { text: "Agenda", contentType: "textonly" }];
    
                $scope.dataSource = groupdata;
            });
        </script>

    Remote Data

    To bind remote data to the GroupButton, you can assign a service data as an instance of ejDataManager to the dataSource property along with the fields mapping.

  • html
  • <div id="groupButton" ej-groupbutton e-groupbuttonmode="radiobutton" e-width="100%" e-showroundedcorner="true" e-datasource="dataManager" e-fields="field" e-query="query" ></div>
  • javascript
  • <script>
            angular.module('GroupBtnCtrl', ['ejangular'])
            .controller('GroupBtnCtller', function ($scope) {   
                $scope.field = { text: "CustomerID" };         
                $scope.dataManager = ej.DataManager({
                    url: "http://mvc.syncfusion.com/Services/Northwnd.svc/"
                });
                $scope.query = ej.Query().from("Orders").take(6);            
            });
        </script>
