Specifies an optional number of data columns to encode for supported barcodes. This property applies to two-dimensional (2D) barcodes only.The form design must supply this property in conjunction with the dataRowCount property to specify a fixed row and column barcode, otherwise the parser must use the rowColumnRatio property to determine the row and column count. The template must not supply the dataColumnCount property unless the dataRowCount property is also supplied. When these properties are used the size of the barcode is fixed. If the supplied data does not fill the barcode it is padded out with padding symbols.Reference_Syntax.dataColumnCount =”string“
