Codeless Barcode Generation

Codeless Barcode Generation (CBG) is a feature that lets you to render barcode images on ASP.NET Webforms by just setting up a special/formatted URL to a standard ASP.NET Image Control without the need of coding VB or C# sentences for barcode rendering.

Codeless Barcode Generation is simple and the concept is very straightforward. For enabling CBG in an ASP.NET web application, you must:

Add a reference to Neodynamic.WebControls.BarcodeProfessional.dll assembly in your project (BIN folder).
Set up the Web.config file of your ASP.NET Web Application so it can recognize CBG. CBG requires you specify an ASP.NET HTTP Handler name to associate it to Barcode Professional assembly. That name can be any you want, but we recommend using BarcodeGen.axd. So, supposing you decide naming CBG in that way, then the web.config entry must be set up as follows:
```
<system.web>      
     ...
     <httpHandlers>
          <add verb="*" path="BarcodeGen.axd" type="Neodynamic.WebControls.BarcodeProfessional.BarcodeProfessional, Neodynamic.WebControls.BarcodeProfessional"/>
     </httpHandlers>
     ...
</system.web>
```

The last step involves creating a special/formatted URL and set up it to ImageUrl property of an Image control. For example, the following URL will generate a Code 39 barcode encoding the value 1234567890

Image1.ImageUrl = "~/BarcodeGen.axd?S=Code39&C=1234567890"

In the sample URL string, the S parameter is for specifying the Barcode Symbology you want to create and the C parameter is for specifying the value to encode in the specified Symbology.
The URL for CBG lets you to specify many other parameters like Bar's Width and Height, DPI, Output Image Format, Font, additional Text, etc. Below is a list of valid parameters and their meanings.

CBG URL Parameters

The following parameters (in the first column) have the same meaning of the associated BarcodeProfessional property (in the second column). The third column shows an example for each parameter. In addition, please refer to Note column for some additional info about each parameter.

IMPORTANT

The URL is composed of a series of param-value pairs.
The first parameter in the URL must be S (for Syambology), followed by C (for value to encode "Code" property) and finally followed by any other parameters.
Param-value pairs are separated by & (ampersand character).
The param-value pairs are each separated by an equal sign.
