Overview ComponentOne QRCode for ASP.NET Webforms allows you to store information about the

item it is associated with. A QRCode (or Quick Response Code) is a two dimensional barcode

that comprises black square dots organized on a white background, in a square grid. It is a

machine readable code that can be read by any imaging device such as a camera or a

smartphone. Unlike barcodes, QRCodes store data in both, horizontal and vertical direction and

therefore, can store upto hundred times more information than the conventional barcodes in

the same amount of space.

QRCode codes are widely used in product packaging or labels to track shipping and other

details; on billboards, newspapers, magazines and websites for branding purposes or redirect

users to other websites.

Key Features

Size: Change the size and resolution of the QRCode as required. See Size for more

information.

Color: Modify the color and create customized QRCodes for your brand. See Color for

more information.

Error Correction: Set upto 30% error correction levels, allowing the data to be

recovered even if the code is damaged. See Error Correction Level for more information.

Encoding: Choose from four encoding options, namely Automatic, Numeric,

Alphanumeric and Byte. See Encoding for more information.

Features

Size A QRCode must be big enough to be scanned easily and small enough to fit into a page

without occupying much space. You can resize the control, as well as the symbols within the

control to improve the resolution of the control. Complete the following steps to change the

size of the control, as well as the symbols.

A QRCode must be square in shape in order to be scanned properly.

In the Designer

1. Resize the QRCode by clicking the edges of the QRCode and drag it till it reaches the

desired height or width.

2. Resize the symbols by clicking the Smart Tag. In the C1QRCode Tasks Menu, set the

SymbolSize property as per your requirement.

3. Alternatively, right click the QRCode and select Properties to open the Properties

window. Set the Height, Width and SymbolSize properties in the Properties window.

In Source View

Set the Height, Width and SymbolSize properties within the <wijmo:C1QRCode> tag to resize

the QRCode.


<wijmo:C1QRCode ID="C1QRCode1" runat="server" Height="150px"

Text="ComponentOne QRCode for ASP.NET Webforms" Width="150px" SymbolSize="5"

/>

In Code

Add the following code to the Page_Load event to set the Height, Width and SymbolSize

properties in code view.

C# Copy Code

C1QRCode1.Height = 150;


9

C1QRCode1.Width = 150;

C1QRCode1.SymbolSize = 5;

VB Copy Code

C1QRCode1.Height = 150

C1QRCode1.Width = 150

C1QRCode1.SymbolSize = 5


When you run your application, notice that the size of the QRCode as well as its symbols is now

bigger.

Color Conventionally, QRCodes are black and white, but you can add color to the control without

distorting the scanning ability of the QRCode. This is the easiest way to customize the QRCode

and add branding to it. Along with color, you may also add a logo or other images on the

QRCode to customize it further. See Add a Logo for more information.

A QRCode with a dark background and light symbols is not recommended, as it may not be

scanned properly.

In the Designer

1. Right click the QRCode and select Properties. The Properties window opens.

2. Set the BackColor and ForeColor properties in the Properties window.

In Source View

Set the BackColor and ForeColor properties within the <wijmo:C1QRCode> tag to add color to

the QRCode.


10


<wijmo:C1QRCode ID="C1QRCode1" runat="server" BackColor="#FFFFCC"

ForeColor="#6600CC" Text="ComponentOne QRCode for ASP.NET Webforms" />

In Code

Add the following code to the Page_Load event to set the BackColor and ForeColor properties

in code view.

C# Copy Code

C1QRCode1.BackColor = System.Drawing.ColorTranslator.FromHtml("#FFFFCC");

C1QRCode1.ForeColor = System.Drawing.ColorTranslator.FromHtml("#6600CC");

VB Copy Code

C1QRCode1.BackColor = System.Drawing.ColorTranslator.FromHtml("#FFFFCC")

C1QRCode1.ForeColor = System.Drawing.ColorTranslator.FromHtml("#6600CC")


When you run your application, notice that the QRCode appears colored.

Error Correction Level This helps in recovering information from the QRCode even when some data is missing or the

QRCode is damaged. This feature is useful in creating customized QRCodes as you can add

images or logos on the QRCode, which may damage the code, but it can still be scanned easily.

The QRCode control has four error correction levels.

Low L: Allows an error margin of 7%.

Medium M: Allows an error margin of 15%.

Quartile Q: Allows an error margin of 25%.

High H: Allows an error margin of 30%.

Complete the following steps to change the error correction level of the QRCode control.

C1.Web.Wijmo.Controls.C1QRCode.ErrorCorrectionLevel.H;

VB Copy Code

C1QRCode1.ErrorCorrectionLevel =

C1.Web.Wijmo.Controls.C1QRCode.ErrorCorrectionLevel.H


The error correction level has been set to H (High) allowing an error margin of 30%.

Code Version The QRCode control has 11 code versions, from 0 to 10. Each code version has a different

configuration of the black and white square dots, that the QRCode is composed of.

Configuration means the number of black and white dots present in a symbol. The arrangement

of the black and white dots is referred to as a module. Starting with version 0 that consists of 21

modules along its height and width, every higher version contains 4 more modules per side.


12

With a rise in the amount of information to be encoded into the QRCode, higher number of

modules are needed in the QRCode, resulting in bigger QRCode symbols. Complete the

following steps to change the code version of the QRCode control.

In the Designer


2. Set the CodeVersion property, as per your requirement.


window. Set the CodeVersion property in the Properties window.

In Source View

C# Copy Code

C1QRCode1.CodeVersion = 8;

VB Copy Code

C1QRCode1.CodeVersion = 8


The code version of the QRCode has been changed to 8, adding more modules to the QRCode.


13

Encoding QRCode consists of four encoding modes to store data more efficiently:

Numeric: Can encode digits 0 - 9.

AlphaNumeric: Can encode digits 0 - 9, upper case letters A - Z and some other

characters like space $ % * + - . / : ),.

Byte: By default, can encode ISO/IEC 8859-1. It may also encode some other sets that

have been defined.

Automatic: Sets the encoding mode depending on the text added to the control.

The alphanumeric mode compresses a message more than the byte mode, but it is unable

to store lower case alphabets and can store only a few punctuation marks.

Complete the following steps to change the encoding mode of the QRCode control.

In the Designer


2. Select the encoding mode from the Encoding combobox, as per your requirement.


window. Set the Encoding property in the Properties window.

In Source View

C# Copy Code

C1QRCode1.Encoding = C1.Web.Wijmo.Controls.C1QRCode.Encoding.Byte;

VB Copy Code

C1QRCode1.Encoding = C1.Web.Wijmo.Controls.C1QRCode.Encoding.Byte


The encoding mode has been changed to Byte, so characters including lower case letters, digits

as well as punctuations can be encoded into the QRCode.

User Scenarios QRCodes can be used for many purposes, such as:

To redirect users to a website,

To make phone calls or send emails without having to type the entire contact number

or email ID,

To fetch coupons and special offers,

To get directions,

To listen to songs or watch videos,

To connect to WIFI networks,

To store feedback forms or other forms,

To promote brands, etc.

The following topics demonstrate some of the many possible uses of QRCodes. The

following topics assume that you are familiar with programming in Visual Studio .NET.

for client-side Web development and utilize the power of jQuery for superior performance and

ease of use.

The ComponentOne Wijmo website at http://wijmo.com/widgets/ provides everything you need

to know about Wijmo widgets, including demos and samples, documentation, theming

examples, support and more.

The client-side documentation provides an overview, sample markup, options, events, and

methods for each widget. To get started with client-side Web development for QRCode for

ASP.NET Webforms, click one of the external links to view our Wijmo wiki documentation.

Note that the Overview topic for each of the widgets applies mainly to the widget, not to the

server-side ASP.NET Webforms control.

Using the Wijmo CDN

You can easily load the client-side Wijmo widgets into your web page using a Content Delivery

Network (CDN). CDN makes it quick and easy to use external libraries, and deploy them to your

users. A CDN is a network of computers around the world that host content. Ideally, if you're in

the United States and you access a webpage using a CDN, you'll get your content from a server

based in the US. If you're in India or China, and you access the SAME webpage, the content will

come from a server a little closer to your location.

When web browsers load content, they commonly will check to see if they already have a copy

of the file cached. By using a CDN, you can benefit from this. If a user had previously visited a

site using the same CDN, they will already have a cached version of the files on their machine.

Your page will load quicker since it doesn't need to re-download your support content.

Wijmo has had CDN support from the very beginning. You can find the CDN page at

http://wijmo.com/downloads/cdn/. The markup required for loading Wijmo into your page

looks similar to this:

 <script src="http://ajax.aspnetcdn.com/ajax/jquery/jquery-1.7.1.min.js" type="text/javascript"></script> <script src="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.17/jquery-ui.min.js" type="text/javascript"></script>  <link href="http://cdn.wijmo.com/themes/rocket/jquery-wijmo.css" rel="stylesheet" type="text/css" title="rocket-jqueryui" />  <link href="http://cdn.wijmo.com/jquery.wijmo-complete.all.2.0.0.min.css" rel="stylesheet" type="text/css" />  <script src="http://cdn.wijmo.com/jquery.wijmo-open.all.2.0.0.min.js" type="text/javascript"></script> <script src="http://cdn.wijmo.com/jquery.wijmo-complete.all.2.0.0.min.js" type="text/javascript"></script>

In this markup, you'll notice that some of the .js files are labeled as *.min.js. These files have

been minified - in other words, all unnecessary characters have been removed - to make the

pages load faster. You will also notice that there are no references to individual .js files. The

JavaScript for all widgets, CSS, and jQuery references have been combined into one file,

respectively, such as wijmo-complete.2.0.0.min.js. If you want to link to individual .js files, see

the Dependencies topic for each widget.

With the ComponentOne Studio for ASP.NET Webforms controls, you can click the Use CDN

checkbox in the control's Tasks menu and specify the CDN path if you want to access the

client-side widgets.

CodeVersion Property Gets or sets the "version" of QR code to generate.

Syntax



<C1DescriptionAttribute(Key="C1QRCode.CodeVersion", Description="Gets or sets

the 'version' of QR code to generate (set to zero to auto-select).")>

<C1CategoryAttribute("Data")>

[C1Description(Key="C1QRCode.CodeVersion", Description="Gets or sets the

'version' of QR code to generate (set to zero to auto-select).")]

[C1Category("Data")]

public System.int CodeVersion {get; set;}

Remarks

The QR specification includes 40 "versions" of QR codes. Higher versions consume more space

and are able to encode more information.

The C1QRCode control can generate QR codes versions one through ten only, which allow

encoding up to 652 digits, or 395 alphanumeric characters, or 271 bytes.

Set the CodeVersion property to zero (the default value) to automatically use the most compact

version able to render the content specified in the Text property.

Public Property Encoding As Encoding

C#



[C1Description(Key="C1QRCode.Encoding", Description="Determines how the Text

should be encoded (automatic, text, numeric, or bytes).")]

public Encoding Encoding {get; set;}

Remarks

More flexible encodings have lower capacity. The C1QRCode control can encode up to 652

digits, or 395 alphanumeric characters, or 271 bytes.

The default value for this property is Encoding.Automatic, which causes the control to

automatically select the most compact encoding that can be used based on the content

specified in the Text property.

EncodingException Property Gets the System.Exception that prevented the Text from being encoded.

Syntax


<System.ComponentModel.BrowsableAttribute(False)>

Public ReadOnly Property EncodingException As System.Exception

C#


86

[System.ComponentModel.Browsable(false)]

public System.Exception EncodingException {get;}

Remarks

The C1QRCode control can be used to encode up to 652 digits, or 395 alphanumeric characters

(uppercase only), or 271 bytes.

If these limits are exceeded, or if any of the control properties is set to values that prevent the

content of the Text property from being encoded, the control remains blank, and the

EncodingException property contains details that explain why the code could not be generated.

Example

The code below sets the Text property and shows a message in case any errors are detected:

C#

c1QRCode1.Text = textBox1.Text; label1.Text = c1QRCode1.EncodingException == null ? string.Empty : c1QRCode1.EncodingException.Message;

87

[C1Description(Key="C1QRCode.ErrorCorrectionLevel", Description="Gets or sets

the error correction level used to create the QR code.")]

public ErrorCorrectionLevel ErrorCorrectionLevel {get; set;}

Remarks

Higher levels of error correction add more redundant information to the QR code, making it

more resistant to damage. Higher levels of error correction also reduce the amount of data that

can be encoded in a given area.

The default value for this property is the lowest level, which produces the most compact QR

codes.

Remarks

Larger values will result in larger images which consume more space but may be easier to for

some scanners to read.

The default symbol size is three pixels, which usually represents a good compromise between

size and readability.

This property must be set to values between 2 and 10.
