    As its shown below, i'm overriding my read function in transport to send ajax request to get data and set it as datasource for the grid but i also have server side paging enabled with virtual scrolling. But i have noticed that i see instead of one, multiple requests(at least two) were sent. I read the posts and people are talking about prefetch and fetch issue. Is there any good solution sofar to fix this issue in my case.
    var dataSource = {
        transport: {
            read: function (options) {
                var success = function (response) {
                var error = function (xhr, status, error) {
                    Ember.Logger.error('Fail response: ' + xhr.responseText + ' (status=' + xhr.status + ' ' + error + ')');
                _this.get('PopulateGridData')(gridUrl, success, error, options.data, 'POST', true, true);
        pageSize: gridPageSize,
        schema: gridSchema,
        serverPaging: true,
        serverSorting: true,
        serverGrouping: true,
        serverFiltering: true,
    var gridOptions = {
        dataSource: dataSource,
        columns: gridColumns,
        editable: gridEditable,
        pageable: {
            refresh: true,
            numeric: false,
            previousNext: false,
        height: gridHeight,
        scrollable: {
            virtual: true,
        groupable: true,
        filterable: true,            
    var grid = Ember.$("#kendo-grid").kendoGrid(gridOptions).data('kendoGrid');
    _this.set('kendoGrid', grid);

    Hello Niloofar,


    As it seems you've already have found the information about how virtualization works, i.e it pre-fetches data in order to achieve more smooth scrolling experience. You could not disable these request as they are integral part of the implementation.
