This is the documentation of the old version of the RadBarcode component, which is currently deprecated. Check out the new version here.

This is an integer value, in the range from 1 to 40, representing the version which one desires to use. Usually, higher-version QR codes are used do accommodate larger amounts of data. If this property is not set, the control internally calculates the lowest possible version and uses it instead. Since Q1 2014 you can take advantage of the ActualVersion property to get the version that the control calculated. In the cases when the Version is set, both properties will be equal.


There are four possible values to choose from - L(Low), M(Medium), Q(Quartile), H(High). These values allow for 7%, 15%, 25% and 30% recovery of symbol code words. Additionally, choosing a higher version of error correction dedicates a larger portion of modules for error correction. Thus, given two QR codes with the same sizes, the one with a lower error correction level would be able to accommodate more data.


This string property represents the data, which will be encoded by the QR control.


There are four values available for this property - Alphanumeric, Numeric, Byte and Kanji. Essentially, this determines the sets of acceptable symbols - numbers, characters, etc.


The Extended Channel Interpretation, in short (ECI) allows for encoding of characters of different character sets. For example, choosing an ECI equal to 8859-7 will allow for encoding characters from the Latin/Greek alphabet. Please note, that the ECI setting is only honored when the Mode property of the control is set to Byte.


This mode is used for messages containing data formatted either in accordance with the UCC/EAN Application Identifiers standard or in accordance with a specific industry standard previously agreed with AIM International.


This property allows for additional data to be applied to the FNC1 data. Please, keep in mind, that this is only applicable with FNC1Mode.FNC1SecondPosition. Additionally, the acceptable data for this property is in the range {a-z}],{[A-Z} and {00-99}.

Essentially, both the FNC1 property and the ApplicationIndicator data is applied to the raw data encoded in the control, allowing for special formatting.
