Enable to reset the datasource with anothers datas

[Foulont Gaetan]

Hello, 

I have this PivotView congured like that : 

                    pivotGridObj = new ej.pivotview.PivotView({

                        dataSource: {

                            enableSorting: true,

                            columns: [],

                            rows: [],

                            valueSortSettings: {

                                headerDelimiter: ' - '

                            },

                            data: ej.data.DataUtil.parse.isJson($scope.data),

                            expandAll: false,

                            formatSettings: [],

                            values: [],

                            filters: [],

                        },

                        showFieldList: true,

                        displayOption: {

                            view: 'Chart'

                        },

                        chartSettings: {

                            chartSeries: {

                                type: 'Column'

                            },

                        },

                        //showToolbar: true,

                        allowCalculatedField: true,

                        //toolbar: ['Chart'],

                        width: '99%',

                        height: '100%',

                    });

                    pivotGridObj.appendTo('#' + id);

How Can I reset the datasource from this specific PivotGridObj with completely another data structure ?

When I try to reset this PivotGrid with this code :

                    pivotGridObj = document.getElementById(id).ej2_instances[0];

                    pivotGridObj.dataSource = {

                        enableSorting: true,

                        columns: [],

                        rows: [],

                        valueSortSettings: {

                            headerDelimiter: ' - '

                        },

                        data: ej.data.DataUtil.parse.isJson($scope.data),

                        expandAll: false,

                        formatSettings: [],

                        values: [],

                        filters: [],

                    };

It doesnt work at all. I just retrieve my precedent field list with my actual new properties.

Here it is Before with initial data :

And After i Try to reset the datasource with other datas :

the data structure is not the same, ie : in new datas I don't have 'OptionPossible' property...

Coud you please help me ?

Thx

Hi Foulont, 

You can refresh “fieldlist” by using below code snippet when refreshing the data. 

Code Snippet: 

refreshBtn.element.onclick = function () { 

    pivotGridObj.engineModule.fieldList = {}; 

}

Hi Foulont, 

Thanks for the reply. 

You need to remove row, column and value fields which are not included in the data. You can remove fields by using following code snippet. 

Code Snippet: 

   var pivotGridObj = new ej.pivotview.PivotView({ 

        enginePopulating: function(args) { 

          var report = {}; 

          report[0] = args.dataSource.rows; 

          report[1] = args.dataSource.columns; 

          report[2] = args.dataSource.values; 

          report[3] = args.dataSource.filters; 

          var pos = 0; 

          while (pos < 4) { 

            if (report[pos]) { 

              for (var cnt = 0; cnt < report[pos].length; cnt++) { 

                if (Object.keys(args.dataSource.data[0]).indexOf(report[pos][cnt].name) == -1) { 

                  report[pos].splice(cnt, 1); 

                  cnt--; 

                } 

              } 

            } 

            pos++; 

          } 

        } 

    }); 

    pivotGridObj.appendTo('#PivotView');
