SSRS无法识别条形码表达式中的数据集

Question

Whenever I use this code

=IIf(JPCI_RPT_ReceiptStatusHeaderBLW.RECEIPT_ID_TYPE = "Trailer ID",  
 Code.StringToBarcode({JPCI_RPT_ReceiptStatusHeaderBLW.trailer_id}), 
 Code.StringToBarcode({JPCI_RPT_ReceiptStatusHeaderBLW.receipt_id_type}) & chr(10) &
 Code.StringToBarcode({JPCI_RPT_ReceiptStatusDetailsBLW.item})

I get the following error...

Name 'JPCI_RPT_ReceiptStatusHeaderBLW' is not declared.

It's checking for dataset right? If not, how do I declare it?

Answer 1

The expression is looking for a field name and you're converting something like Crystal Reports to SSRS. In SSRS you refer to a field value with Fields!FieldName.Value.

Ass u me ing that you have a dataset with necessary fields, your expression would be something like:

=IIF(Fields!RECEIPT_ID_TYPE.Value = "Trailer ID",  
    Code.StringToBarcode(Fields!trailer_id.Value), 
    Code.StringToBarcode(Fields!receipt_id_type.Value) & chr(10) &
    Code.StringToBarcode(Fields!item.Value) )

You had missed a closing parenthesis as well, but the error check didn't get that far.
