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#

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.

SqlBulkCopy for insert multiple rows of data into table in SQL Server

Sometimes we need to insert bulk amount of data into a table in SQL. We can insert bulk data to SQL in different methods. Here we are going to demonstrate how to insert large amount of data using SQL Bulk Copy method.

Example of SQL BulkCopy method

Here we are going to insert multiple rows of sample data into Employee table. First of all create a table in SQL named Employee. After that  create sample data for employee table and finally this multiple rows of employee data insert into table using SQL bulk copy method.

Create a Table in SQL 

CREATE TABLE Employee
(
ID INT,
EmpName varchar(200),
Department varchar(200),
DOB DateTime
);

SQLMulkCopy Example in SQL Server

SQLMulkCopy Example in SQL Server

C# Code to generate sample data and insertion using SQL Bulk Copy

private void loadDataBySQLBulkCopy()
        {
            DataTable dtTblEmployee = new DataTable();
            dtTblEmployee.Columns.Add("ID", typeof(Int32));
            dtTblEmployee.Columns.Add("EmpName", typeof(String));
            dtTblEmployee.Columns.Add("Department", typeof(String));
            dtTblEmployee.Columns.Add("DOB", typeof(DateTime));

            DataRow dtrow = dtTblEmployee.NewRow(); // Create New Row
            dtrow["ID"] = 1; //Bind Data to Columns
            dtrow["EmpName"] = "Wazeem";
            dtrow["Department"] = "Admin";
            dtrow["DOB"] = "1990-10-16 12:00:00.000";
            dtTblEmployee.Rows.Add(dtrow);

            dtrow = dtTblEmployee.NewRow(); // Create New Row
            dtrow["ID"] = 2; //Bind Data to Columns
            dtrow["EmpName"] = "Aslam";
            dtrow["Department"] = "HR";
            dtrow["DOB"] = "1987-05-16 12:00:00.000";
            dtTblEmployee.Rows.Add(dtrow);

            dtrow = dtTblEmployee.NewRow(); // Create New Row
            dtrow["ID"] = 3; //Bind Data to Columns
            dtrow["EmpName"] = "John";
            dtrow["Department"] = "Finance";
            dtrow["DOB"] = "1992-12-11 12:00:00.000";
            dtTblEmployee.Rows.Add(dtrow);

            dtrow = dtTblEmployee.NewRow(); // Create New Row
            dtrow["ID"] = 4; //Bind Data to Columns
            dtrow["EmpName"] = "Mishal";
            dtrow["Department"] = "Infra structure";
            dtrow["DOB"] = "1989-04-01 12:00:00.000";
            dtTblEmployee.Rows.Add(dtrow);

            SqlBulkCopy bulkCopy = new SqlBulkCopy(
                "server=TEST;database=TEST;uid=test;password=test",
                SqlBulkCopyOptions.TableLock);
            bulkCopy.DestinationTableName = "dbo.Employee";
            bulkCopy.WriteToServer(dtTblEmployee);

How to merge two data tables in ASP.Net/C# OR Merge 2 DataTables and store in a new one in ASP.Net/C#

October 14, 2012 Leave a comment

Merge multiple data-tables data into a another data-table using C#/ASP.Net

Here we are going to demonstrate a sample application which shows merge two data tables  in ASP.Net. In this sample we are having two data tables with some data and merge data of each tables data. We binds first data table to a data grid second one to another grid and third data grid binds with merged data table.

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

October 2, 2012 4 comments

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>

Sample Application of Navigation Menu/Bread Crumbs

  <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" />

Resize and drag a div in ASPX page/HTML Page

Here we are going to demonstrate making a div that can be drag and resize by users. We are achieving this drag and resize of div functionality using Jquery files. We already posted some article related with Jquery and Javascript. Here we are again demonstrating a detailed post regarding Draggable and Resizable div using Jquery files.

Drag able Re-sizable Div in HTML/ASPX Page

Drag able and Resizable Div using Jquery in HTML/ASPX Page

For implementing drag and resize Div, we need to download following jquery and css files and included in the ASPX/HTML page.

1. jquery.min.js          – Download from here 

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" />

HTML/ASPX Page for creating drag able and re sizable div

 }
 </style>
 <script type="text/javascript">
$(document).ready(function () {
$("#resizediv").resizable();
$("#resizediv").draggable();
});
</script>
</head>
<body>
 <form id="form1" runat="server">
 <div id="resizediv">
 Drag me ... or Resize me....<br />
 This is a Div that can be Drag and Resize by you.. .
