$(function(){
 var grid = $("#grid").kendoGrid({
            dataSource: {
                type           : "odata",
                transport      : {
                    read: "http://demos.kendoui.com/service/Northwind.svc/Orders"
                },
                schema         : {
                    model: {
                        fields: {
                            OrderID  : { type: "number" },
                            Freight  : { type: "number" },
                            ShipName : { type: "string" },
                            OrderDate: { type: "date" },
                            ShipCity : { type: "string" }

                    title : "Order Date",
                    width : 100,
                    format: "{0:MM/dd/yyyy}"
                },
                {
                    field: "ShipName",
                    title: "Ship Name",

                }
            ]
        }).data("kendoGrid");

 $("#btnExport").click(function(e) {

 var dataSource =  $("#grid").data("kendoGrid").dataSource; 
     var filteredDataSource = new kendo.data.DataSource( { 
         data: dataSource.data(),

     filteredDataSource.read();
     var data = filteredDataSource.view();

     var result = "data:application/vnd.ms-excel,";

     result += "<table><tr><th>OrderID</th><th>Freight</th><th>Order Date</th><th>Ship Name</th><th>Ship City</th></tr>";

     for (var i = 0; i < data.length; i++) {
         result += "<tr>";

         result += "<td>";
         result += data[i].OrderID;
         result += "</td>";

You can make a controller method and pass the grid's request as follows

public void Export([DataSourceRequest] DataSourceRequest gridRequest){
    // your logic goes here
}
