Initializing the Barcode
The following example demonstrates how to define the Barcode.
@(Html.Kendo().Barcode()
.Name("barcode")
<kendo-barcode name="barcode"></kendo-barcode>
Basic Configuration
To configure the Barcode, pass the configuration options as attributes:
The name of the Barcode is mandatory. It specifies the "id" attribute of the widget.
You can select the appropriate encoding (symbology) from the available options. Specify it by passing an
enumvalue to the encoding method.
@(Html.Kendo().Barcode()
.Name("barcode")
.Value("10110110")
.Encoding(BarcodeSymbology.Code128)
.Width(200)
.Height(100)
.Border(border => border.Color("red").Width(2)))
)
<kendo-barcode name="barcode" value="10110110" type="BarcodeSymbology.Code128" width="200" height="100">
<border color="red" width="2"/>
</kendo-barcode>
Functionality and Features
The Barcode supports a set of encoding types.
Referencing Existing Instances
To reference an existing Barcode instance, use the jQuery.data() configuration option. Once a reference is established, use the Barcode client-side API to control its behavior.
// Place the following after the declaration of the Barcode for ASP.NET Core.
<script>
$(function() {
// The Name() of the Barcode is used to get its client-side instance.
var barcode = $("#barcode").data("kendoBarcode");
barcode.value("foo") // Supply a valid value for that encoding. Then, the Barcode will redraw automatically.
});
</script>
