There is no build in method to export jqgrid data to pdf. You have to use third party tools( I personally like iTextSharp which can be downloaded from Here . You have to create action method for printing the grid data in your controller.
Here is also another one example one guy made.
Here is also another example in trirand. If you see the source code they are using iTextHsarp.
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using JQGridMVCExamples.Models;
using Trirand.Web.Mvc;
using System.IO;
//
// For PDF export we are using the free open-source iTextSharp library.
//
using iTextSharp.text;
using iTextSharp.text.pdf;
using System.Data;
namespace JQGridMVCExamples.Controllers.Grid
{
public partial class GridController : Controller
{
// This is the default action for the View. Use it to setup your grid Model.
public ActionResult ExportPDF()
{
// Get the model (setup) of the grid defined in the /Models folder.
var gridModel = new OrdersJqGridModel();
var ordersGrid = gridModel.OrdersGrid;
// Setting the DataUrl to an action (method) in the controller is required.
// This action will return the data needed by the grid
ordersGrid.DataUrl = Url.Action("PDFGrid_DataRequested");
// customize the default Orders grid model with custom settings
// NOTE: you need to call this method in the action that fetches the data as well,
// so that the models match
SetPDFExportGrid(ordersGrid);
// Pass the custmomized grid model to the View
return View(gridModel);
}
// This method is called when the grid requests data
public JsonResult PDFGrid_DataRequested()
{
// Get both the grid Model and the data Model
// The data model in our case is an autogenerated linq2sql database based on Northwind.
var gridModel = new OrdersJqGridModel();
var northWindModel = new NorthwindDataContext();
// customize the default Orders grid model with our custom settings
SetPDFExportGrid(gridModel.OrdersGrid);
// Save the current grid state in Session
// We will later need it for PDF Export
JQGridState gridState = gridModel.OrdersGrid.GetState();
Session["gridState"] = gridState;
// return the result of the DataBind method, passing the datasource as a parameter
// jqGrid for ASP.NET MVC automatically takes care of paging, sorting, filtering/searching, etc
return gridModel.OrdersGrid.DataBind(northWindModel.Orders);
