Email-New Html5 input element

In most of the websites we have contact forms and other forms where we have some standard inputs like Phone,Email and Website URL and those are widely used in any site and has specific features. Email is one of the most standard used input elements which are used in our forms. Till HTML 4.1 we have standard input type text and that’s for we were doing input validation with java script and other technologies. While we all know HTML5 is there and it’s contains lots of goodies, One of them is email input types.

Email input type comes with HTML5 as standard input type. It has all validation by default which are required for email input like we must have @ and . while we entered email input type.

string.format escape sequence in c#

Recently I was working on something and I need to put a curly bracket on the string with a string.format function but I was not aware how to to do it. So I did some search on internet and found how to give escape sequence in string.format. Suppose You need to put curly bracket then you have write two ‘{{‘ instead of { to put ‘{‘ and same way ‘}}’ to put ‘}’

Let’s take simple example. Following is a code where I am printing simple string with string.format and Response.Write.

using System;
using System.Web.UI;

namespace CallBack
    public partial class Index : System.Web.UI.Page
        protected void Page_Load(object sender, EventArgs e)
            Response.Write( string.Format(@"{{ escape sequence for string format from {0}}}", "DotNetJalps"));


Now let’s run that example in browser and let’s see how it goes.

C#,Escape Sequence,String.format

That’s it. It’s very easy to use.Hope you liked it. Stay tuned for more..Happy Programming.

Difference between generic handler and http handler- ASP.NET

Generic handler:

As per MSDN Generic Handler is a default handler which will have @webhandler directive and has .ashx extension this generic handler is not having UI but it provides response when ever any request made to this handler.

HTTP Handler:

HTTP Handler is a process which runs and continue to server request and give response based on the request handling code. This handler does not have UI and need to configured in the web.config against extensions. One of the great example of Http Handler is page handler of ASP.NET which serves .aspx pages request.

Difference between generic handler and http handler:

Following is a main differences between http handler and generic handler.
  1. Generic handler has a handler which can be accessed by url with .ashx extension while http handler is required to be configured in web.config against extension in web.config.It does not have any extension
  2. Typical example of generic handler are creating thumbnails of images and for http handler page handler which serves .aspx extension request and give response.

how to vertically middle align text in div-HTML tip

Recently in one of the project I have to vertical align text in div. so doing some internet search I have found there are no proper way to do it. So I thought it would be good do share this within my readers.

Here is the code do vertically align text in div.

<div style="width: 25%;border:solid 1px red;display: table;vertical-align: middle;float:left;height:100px;">
<div style="display: table-cell;vertical-align: middle;">this is a very long text this is a very long text this is a very long text this is a very long text this is a very long text this is a very long text </div>

Here in above code you can see that I have created two divs first one will serve container for other div and other div has the text which I want to align vertically in div. So in container div you can see I have given its style to display table and in child div which has the text I have given its display style to table-cell and given vertical-align property to middle. 

That’s it now when you run this in browser you can see text is vertically aligned.

ASP.NET Page Methods with Parameters

In earlier post I have written how we can use page methods to call server-side from the java script. In this post I am going to explain How we can pass parameters to page methods with java script.
So let’s take a simple example to see how we can pass parameters to the page methods. I am going to create a page method Hello World which takes name as parameter and return a string to greet user from that page method below is code for that.

using System;
using System.Web.Services;

namespace PageMethods
 public partial class Test : System.Web.UI.Page
    public static string HelloWorld(string name)
        return string.Format("Hi {0}",name);

As you can see in following page method it’s returning string with greetings. So now our server-side code is completed. Now it’s time to write HTML and java script code for this. Following is code for java script.

<script type="text/javascript">
 function GreetingsFromServer() {
     var name = 'Jalpesh';
     PageMethods.HelloWorld(name,OnSuccess, OnError);
     return false;
 function OnSuccess(response) {
 function OnError(error) {

As you can see in above code I have created a function called ‘GreetingsFromServer’ which called page method helloworld with passing name parameter. Other two functions are handlers for the page methods Onsucess will be called if page method is called successfully without error other wise it will call onError method and alert error message.

Now we are done with java script so its time to write HTML code. So let’s write a HTML code for this page.

<%@ 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 with parameter demo</title>
 <form id="form1" runat="server">
     <asp:ScriptManager runat="server" EnablePageMethods="true" EnablePartialRendering="true">

     <asp:button ID="btnHelloWorld" runat="server" Text="Greet User" OnClientClick="return GreetingsFromServer();"/>

As you can see from above code I have enabled page methods true with script manager and then I have called JavaScript function “GreetingsFromServer” on button client click. So it’s now time to run this code in browser. Following is output as expected.


That’s it. It’s very easy hope you liked it..Stay tuned for more…Happy programming
