I was able to solve my issue using following AJAX
$.ajax({ url: webManager.resolveUrl("~/maint/GetCustomerComments"), method: "POST", data: { invoices: invoicesList }, success: function (result) {var grid = $("#CustomerCommentsGrid").data("kendoGrid");var dataSource = new kendo.data.DataSource({ data: result.Data}); grid.setDataSource(dataSource); grid.dataSource.read();}, error: function () { alert('an error occurred');}});
Needed to know how to set datasource for the grid.
