public abstract class BarcodeBase : Control

Constructors

BarcodeBase()

Initializes a new instance of the BarcodeBase class.

Declaration
protected BarcodeBase()

Fields

RenderChecksumProperty

Identifies the RenderChecksum dependency property.

Declaration
public static readonly DependencyProperty RenderChecksumProperty
Field Value
System.Windows.DependencyProperty

RestrictAspectRatioProperty

Identifies the RestrictAspectRatio dependency property.

Declaration
public static readonly DependencyProperty RestrictAspectRatioProperty
Field Value
System.Windows.DependencyProperty

ShowChecksumProperty

Identifies the ShowChecksum dependency property.

Declaration
public static readonly DependencyProperty ShowChecksumProperty
Field Value
System.Windows.DependencyProperty

ShowTextProperty

Identifies the ShowText dependency property.

Declaration
public static readonly DependencyProperty ShowTextProperty
Field Value
System.Windows.DependencyProperty

TextProperty

Identifies the BarcodeText dependency property.

Declaration
public static readonly DependencyProperty TextProperty
Field Value
System.Windows.DependencyProperty

Properties

BarcodeEncodedText

This is the encoded text.

Declaration
protected string BarcodeEncodedText { get; set; }
Property Value
System.String

Checksum

This is the checksum, calculated on the barcode.

Declaration
protected string Checksum { get; set; }
Property Value
System.String

RenderChecksum

Gets or sets a value that determines whether the checksum should be included in the barcode's image. By default this property is set to true. Scanning barcodes with most of the standards will be possible only when they include checksum. You could use this property to turn off the auto calculated checksum if you have already calculated it yourself and passed it as part of the Text property.

Declaration
public bool RenderChecksum { get; set; }
Property Value
System.Boolean

true if the checksum should be included in the barcode's image; otherwise false. The default is true.

RestrictAspectRatio

Gets or sets a boolean value, indicating whether the aspect ratio should be preserved or not.

Declaration
public bool RestrictAspectRatio { get; set; }
Property Value
System.Boolean

ShowChecksum

Gets or sets a value that determines whether the checksum will be displayed at the end of the text.

Declaration
public bool ShowChecksum { get; set; }
Property Value
System.Boolean

true if the checksum is displayed at the end of the text; otherwise false. The default is true.

ShowText

Gets or sets a value that determines whether the text will be displayed.

Declaration
public bool ShowText { get; set; }
Property Value
System.Boolean

true if the text is displayed; otherwise false. The default is true.

Text

Gets or sets the Text entered by the user.

Declaration
public string Text { get; set; }
Property Value
System.String
