Introduction

This is a simple application for beginners that shows how to drag and drop a title onto canvas using HTML 5 and CSS tools. We know that HTML 5 is the advanced version of HTML. Basically HTML 5 can be used to develop 3D applications. This article is intended to help with the use of HTML5 tools to develop drag and drop a title onto a canvas application. CSS is the acronym for Cascading Style Sheet that is used for design. CSS defines how HTML elements are to be displayed. Canvas is an important tag of a HTML 5 that is used to show the image and text in a HTML 5 application. I hope this article helps to drag and drop titles onto canvas using HTML 5 and CSS tools.

Step 1 : First Open a HTML editor such as Notepad.

Open start->Notepad.
The name of editor is "drag".

Step 2 : Create a Folder on a desktop.

Right-click on desktop->new->Folder.
Name of folder is "drop".

Step 3 : Open Visual Studio.

Go to file -> New->Projects.
Crete an ASP. NET Web Application.
Name of "Drag.aspx".

Step 4 : Add a HTML file to your web application.

Right-click on Solution Explorer.
Add->add new item->HTML form.
The Name of the HTML form is "Drop.html".

Step 5 : Add a js file to the application. The T1.js file provides the functionality of dragging a title from one frame and dropping to another frame and the T2.js file is used to change a color of frame after dropping the title on a frame.

Code

<script type="text/javascript" src="T1.js"></script>
<script type="text/javascript" src="T2.js"></script>

Step 6 : Now in this step we add a css file that sets all properties of a table. Through css we set color, size and font properties of the table.

Code

table.userTable td a
{

display:inline;

width: 20em;

height: 2.4em;

border: solid 1px #999999;

text-decoration:none;

text-align: center;

margin-bottom: .5em;

background-color:transparent;

cursor:default;

}
.draggedUser
{

zoom: 2;

opacity: .3;

moz-opacity: .4;

filter: alpha(opacity=30)

}
#unassignedUsers:hover
{

ackground-color:Blue;

}
#restrictedUsers:hover
{

background-color:Fuchsia;

}
#powerUsers:hover
{

background-color:Green;

}

Step 7 : In this step we define a table body container.

Code

<tbody>
    <tr>
    <td id="unassignedUsers" class="userList">
    <a href="#" draggable="true">Csharpcorner</a>
    <a href="#" draggable="true">Mindcracker</a>
    <a href="#" draggable="true">mcn professionals</a>
    <a href="#" draggable="true">mcn solutions</a>
    </td>
<td id="restrictedUsers" class="userList">
    </td>
    <td id="powerUsers" class="userList">
    </td>
    </tr>
</tbody>

Step 8 : Set a message that shows completion of dragging a title from one table to another table.

Code

<tfoot>
<td id="unassignedUsersHelp">Drag and drop example</td>
<td id="restrictedUsersHelp">Drag and drop example</td>
<td id="powerUsersHelp" >Drag and drop example</td>
</tfoot>

Step 9 : The complete drag and drop application code is given below.

Code

<html>
<head>
<title>Drag and Drop </title>
<link href="style.css" rel="stylesheet" type=
"text/css">
<script type="text/javascript" src="T1.js"></script>
<script type="text/javascript" src="T2.js"></script>
</head>
<body bgcolor="#ff99cc">
<form>
<fieldset>
<legend>Tom application</legend>
<table class="userTable">
<thead>
<tr>
<th bgcolor="Red">Company</th>
<th>Developer</th>
<th>Trainee</th>
</tr>
</thead>
<tbody>
    <tr>
    <td id="unassignedUsers" class="userList">
    <a href="#" draggable="true">Csharpcorner</a>
    <a href="#" draggable="true">Mindcracker</a>
    <a href="#" draggable="true">mcn professionals</a>
    <a href="#" draggable="true">mcn solutions</a>
    </td>
<td id="restrictedUsers" class="userList">
    </td>
    <td id="powerUsers" class="userList">
    </td>
    </tr>
</tbody>
<tfoot>
<td id="unassignedUsersHelp">Drag and drop example</td>
<td id="restrictedUsersHelp">Drag and drop example</td>
<td id="powerUsersHelp" >Drag and drop example</td>
</tfoot>
</table>
</fieldset>
</form>
</body>
</html>
