Specifies an optional number of data rows to encode for supported barcodes. This property applies to 2D barcodes only.The form design can supply this property in conjunction with the dataColumnCount property to specify a fixed row and column barcode. Otherwise the rowColumnRatio property plus the actual length of the data being inserted determine the row and column count. The dataRowCount property cannot be present unless the dataColumnCount property is also present. When these properties are used the size of the barcode is fixed. If the supplied data does not fill the barcode the remaining cells are padded out with padding symbols.Reference_Syntax.dataRowCount = “string“
