Page methods in

Now days people are looking for richer and fluid user experience and to create that kind of application Ajax is required. There are several options available to call server-side function from JavaScript with ASP.NET Ajax and if you are using 2.0 or higher version of Microsoft.NET Framework then page methods are one of best options available to you.

Page methods are available there from 2.0. If works just like a normal web service. You can direct call that page methods directly from the JavaScript.

Let’s take a real world example. I will call java script on button client click event and then from that we call server-side function from the page methods. So let’s create a project called Pagemethods via File->New Project like following

Page methods in ASP.NET

After that I have created a page called test.aspx and now I am creating page method called GetCurrentDate like following.

using System;
using System.Web.Services;

namespace PageMethods
   public partial class Test : System.Web.UI.Page
      public static string GetCurrentDate()
          return DateTime.Now.ToShortDateString();

As you can see in above there is  a web method called GetCurrentDate which is just returning short date in string format. Here you will notice that I have putted WebMehod attribute for that method this is a perquisite for page methods to make available in client side.

Now let’s write code for HTML and JavaScript and following is a HTML code for that.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Test.aspx.cs" Inherits="PageMethods.Test" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">

<html xmlns="">
<head runat="server">
   <title>Page Method demo</title>
   <form id="form1" runat="server">
       <asp:ScriptManager runat="server" EnablePageMethods="true" EnablePartialRendering="true">

       <asp:button ID="btnGetDate" runat="server" Text="Get date from server" OnClientClick="return GetDateFromServer();"/>

As you can see in above code I have taken an ASP.NET button which call client side function GetDateFromServer which call page methods and get server date. Following is a javascript code for that.

<script type="text/javascript">
   function GetDateFromServer() {
       PageMethods.GetCurrentDate(OnSuccess, OnError);
       return false;
   function OnSuccess(response) {
   function OnError(error) {

As you can see in GetdateFromServer methods I have called our page method Get Current date and you can see PageMethods object in JavaScript has all the methods which are available from server-side. I have passed two event handler for success and error. If any error occurred then it will alert that error and on successful response from server it will alert a current date.

So it’s now time to run that in browser.So once you pass F5 then once you click ‘Get date from server’ the output is like following as expected.


That’s it as you see it’s very easy.Hope you like it. Stay tuned for more.Till then happy programming..

Shout it

kick it on


  1. Thank You very much ! It was very helpful. I also passed a parameter like this
    PageMethods.your_method_name(your_parameter_var,OnSuccess, OnError);

    1. Thanks for kind words. Yep you can pass parameter also.

How to use migration with Entity Framework Core

Entity framework core is  the lightweight, extensible and cross-platform version of Entity Framework. Before some time, Microsoft has Released a new version of Entity Framework RC2. I have written a couple of blog post about Entity framework code first migration earlier for Entity framework 6.0. So there was a couple of request coming for writing a blog post about Entity Framework Core RC2 migration. So I thought it will be a good idea to give an overview how database migration works in Entity Framework Core RC2. This post will cover a basic scenario where we are going to create the database with existing ASP.NET Identity migration and then we are going to create a new model and have that migration applied in the database.

How to use Entity Framework Migrations: Let’s get started, To demonstrate entity framework core migrations, I am going to create a sample core web application like following.

Once we select core application it will appear the following dialog.

Creating PDF with ASP.Net MVC and RazorPDF

Update: I have written a new blog post about better approach to create a PDF with mvc- You can find that following location.- A Better Solution to create PDF with Rotativa and ASP.NET MVC
In this post we are going to learn how we can easily create PDF from ASP.Net application with the help of Razor PDF NuGet package.

About Razor PDF:
This NuGet package is created by Al Nyveldt It internally uses ITextSharp an open source PDF convertor library. RazorPDF uses Razor View engine to create iTextXML which is in tern used to produce PDF file. You can get more information about that at below link.

Example(Creating PDF with ASP.Net MVC):
So what we are we waiting for ? Let’s create a simple example. To create example first thing we need to a create and ASP.Net MVC application.
