This is a quick post in response to a question asked by my one of the follower on Facebook and the answer is pretty simple. Here is the question I have been asked:-

This is a quick hit post. If you are developing a form in ASP.NET you may be noticed that when we press enter key even without writing any information in textboxes, form gets post (submitted). So, how do you stop it?

Another title of this post would be “Say bye-bye to Postbacks”. Sometimes we need to stop annoying post-backs on ASP.NET Web Pages. For example, when one click the ASP.NET button on webpage, by default page gets post-back. So, how we stop this by keeping proper code-behind method calls. Let’s look at one case.

Another easy but interesting stuff I found today on http://in.jagran.yahoo.com/epaper/ (Hindi Language e-News Paper) and decided to develop it on my PC. If you open Google and search by typing “Image Map in HTML” you will get huge response and you can start learning this from there but here I got something different for you.

In this quick post you will learn how to find elements in the DOM that have the specified attribute with a value beginning exactly with a given string. Actually, this problem was asked by my one of the friend Md Ibrahim Rashid, who is from Kolkata at Kolkata Geeks Developer Conference 2012. Let’s look at the HTML Markup and a problem:-     < div >         < a id ="abc" href ="#"> Link 1 </ a >< br />         < a id ="bdc" href ="#"> Link 2 </ a >< br />         < a id ="acd" href ="#"> Link 3 </ a >< br />         < a id ="cca" href ="#"> Link 4 </ a >< br />         < a id ="adc" href ="#"> Link 5 </ a >< br />     </ div > In the above markups, I have 5 links with id attribute. If you look at id attribute’s value, you will find 3 id’s value sta

I can see many websites today having no such feature like when user clicks on label control textbox gets focus. As you can see in animated image given below, in first login set when I clicked on label control text box not getting focus and the same in another login set textbox gets focus and we can start typing. Reason: Such websites not using AssociatedControlID property. Use of AssociatedControlID property We use AssociatedControlID property to associate a Label control with another server control on a Web form. When a Label control is associated with another server control, its attributes can be used to extend the functionality of the associated control. You can use the Label control as a caption for another control, or you can set the tab index or hot key for an associated control. When the AssociatedControlID property is set, the Label control renders as an HTML label element, with the for attribute set to the ID property of the associated control. You can set

Introduction SSL (Secure Socket Layer) is a cryptographic protocol developed by Netscape to provide communications security on internet. Cryptographic technology uses two keys to encrypt data, one for public (public key) and another for recipient (secret key). SSL enabled website communicates with web server by using security channel (secret key) that prevents tempering, eavesdropping (or simply say hacking). Mostly probably SSL is used on login section, payment system, online banking system etc that is very sensitive information for organization. When we enable the SSL for website URL will start with https:// instead of http://. Requirements To test this, you should have IIS installed. No need of extra software like Visual Studio or any other website development kit because only a single HTML file can be tested. Follow the steps to enable SSL on Windows Server 2008 R2 Operating System; another Operating System may have little difference. Step 1 Open IIS Manger and

Introduction Before writing anything, I will say this is a very simple article for those who don't know how to create website in IIS and navigate that website without opening Visual Studio IDE always. Means just open the browser and navigate that local websites. Actually such system has very huge advantages if we are working on intranets (in simple, local internet called intranet). Means if we have dozen of computers under network and one of the PC has server configuration then such websites can be available on each PC on network. Many companies has adopted such service, BSL is one the example who is using such services since decade. Look at below, I have opened a ASP.NET website without Visual Studio IDE.   In the above browser snap, 'localhost' url part may be replaced by computer name or IP. Look at snap below.   Okay, introduction is over now. Let's configure such system for our website developments. Follow the steps for the same. Note: Please be sure of IIS
