How to access all types of server controls in ASP.Net using Javscript/JQuery OR Clear all server controls values using javascript or Jquery
How to access server side controls in ASP.Net using Javascript/JQuery
Using client side script such as JavaScript and Jquery, we can access all server side controls from ASPX page and it will get more performance on web application as it is not causing post back. While development we are frequently facing a feature to implement that “Clear All” function in the ASPX page. Suppose in a User Entry form, most probably there will be having a button for clear all values that user was trying to enter previously.
Get all textboxes, radio buttons and checkboxes in an ASPX page from JavaScript
To access all server side textbox controls in an aspx page using JavaScript, we have to find all controls with tag name is input and type is text. Below mentioned code will access all textboxes in a aspx page from JavaScript and clear those values to empty. The type of the radio button is ‘radio’ and checkbox is ‘checkbox’.
var elements = document.getElementsByTagName("input");
for (var ii = 0; ii < elements.length; ii++) {
if (elements[ii].disabled == false) {
if (elements[ii].type == "text") {
elements[ii].value = "";
}
if (elements[ii].type == "radio") {
elements[ii].checked = false;
}
if (elements[ii].type == "checkbox") {
elements[ii].checked = false;
}
}
}
How to access dropdown list control in an ASPX Page using Javscript/JQuery
The tagname for the dropdownlist and listbox controls in an aspx page is ‘select’. We can access all dropdown list in a aspx page by checking tagname of each controls as same as below sample code.
var select = document.getElementsByTagName("select");
var length = select.length;
for (i = 0; i < length; i++) {
for (var j = 0; j < select[i].length; j++) {
select[i][j].selected = false;
}
}
A simple example for accessing all server controls in an aspx page from javscript/jquery
We are demonstrating a sample web page containing different server controls like textbox, dropdownlist, checkbox, radiobutton, listbox etc.. and clearing all this values to default by using javscript/jquery. Here we are accessing all serverside controls without knowing their ids and names.

How to implement CAPTCHA image validation in ASP.Net/C# OR CAPTCHA image validator Sample in ASP.Net/C#
DOWNLOAD SOURCE CODE FOR CAPTCHA IMAGE VALIDATION IN ASP.NET
What is CAPTCHA and why we are using CAPTCHA
A CAPTCHA is a type of challenge-response test used in computing as an attempt to ensure that the response is generated by a human being. The process usually involves a computer asking a user to complete a simple test which the computer is able to grade. These tests are designed to be easy for a computer to generate but difficult for a computer to solve, but again easy for a human. If a correct solution is received, it can be presumed to have been entered by a human. A common type of CAPTCHA requires the user to type letters and/or digits from a distorted image that appears on the screen. Such tests are commonly used to prevent unwanted internet bots from accessing websites, since a normal human can easily read a CAPTCHA, while the bot cannot process the image letters and therefore, cannot answer properly, or at all.
How to implement CAPTCHA validation/CAPTCHA verification in ASP.Net/C#
CAPTCHA image can be generated using ASP.Net codes and we can validate the code that user enter with the code in the CAPTCHA image. Here we are going to do a sample application that demonstrates how to create a CAPTCHA image using C# codes and how we can validate the user inputs with the CPATCH code. We are having two aspx pages and one class .cs file in the sample application.
A very simple application sample for CPTCHA validation
In the page load, first of all we are creating a 6 digit random number and stored in the session. By using this random number we creates a image suing System.Drawing package by giving some width,height,font family and alignment of the numbers, So the user can able to view the codes in the CAPTCHA image but it is difficult to read using system.

How to show Password Strength image to user in ASP.Net
Register/change password pages on most of the application showing password strength information to user while entering password in the textbox. It allows to user to enter a strong password for register the pages. We can implement Password Strength Checker in different methods in ASP.Net application. Its better to do it in the client side itself so that user doesn’t feels post back in the page.
Implement Password Strength Checker using Jquery
Here we are going to demonstrate a sample application to implement Password Strength Checker using Jquery. The application shows the status of entered password by each alphabet changes in the textbox such as Week, Good, Strong etc..

How to create breadcrumbs in ASP.Net/C# OR Show Navigations for each pages in ASP.Net/C# OR How to implement Sitemap in ASP.Net
DOWNLOAD SOURCE CODE FOR BREADCRUMB EXAMPLE IN ASP.NET
What is breadcrumbs and what is the use of it?
Breadcrumbs typically appear horizontally across the top of a web page, often below title bars or headers. They provide links back to each previous page the user navigated through to get to the current page or-in hierarchical site structures-the parent pages of the current one. Breadcrumbs provide a trail for the user to follow back to the starting or entry point. A greater-than sign (>) often serves as hierarchy separator, although designers may use other glyphs <http://en.wikipedia.org/wiki/Glyph> (such as » or >), as well as various graphical treatments.
Typical breadcrumbs look like this:
Home page > Section page > Subsection page
How to implement breadcrumbs in ASP.Net/C# pages
In order to implement breadcrumbs in ASPX pages, we can use new pages called sitemaps. In ASP.NET the menu can be stored in a file to make it easier to maintain. This file is normally calledweb.sitemap, and is stored in the root directory of the web.
BREADCRUMB EXAMPLE IN ASP.NET
Example for implementing sitemaps in ASP.Net/C# pages
We are going to demonstrate sample ASP.Net application for implementing Breadcrumbs in ASPX pages. First of all create a new ASP.Net project and create three pages home.aspx, aboutus.aspx and contactus.aspx. Then create a sitemap file by “Add New item > SiteMap” and mention the hierarchy of the pages in the sitemaps as follows
<?xml version="1.0" encoding="utf-8" ?> <siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" > <siteMapNode url="Default.aspx" title="Home" description="Home Page"> <siteMapNode url="ContactUs.aspx" title="Contact US" description="Contact US Page" /> <siteMapNode url="About.aspx" title="About" description="About " > <siteMapNode url="AboutCompany.aspx" title="About Company" description="About Our Company" /> <siteMapNode url="AboutService.aspx" title="About Service" description="About Our Services" /> </siteMapNode> </siteMapNode> </siteMap>
Once we created sitemap and mentioned the hierarchy of the pages we need to map this sitemaps into all pages that we need to show navigation as follows.
<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" /> <asp:SiteMapPath ID="SiteMap1" runat="server"> </asp:SiteMapPath>

2. jquery-ui.min.js – Download from here
3. jquery-ui.css – Download from here
After downloading above files we need to create a HTML/ASPX Page and include above files as mentioned below.
<script src="jquery.min.js" type="text/javascript"></script> <script src="jquery-ui.min.js" type="text/javascript"></script> <link rel="stylesheet" href="jquery-ui.css" type="text/css" media="all" />
