Get base enum lables insted enum ids in SSRS report

Generally in ssrs report to get baseenum labels instead basenum element id , we can do that in two ways

Way1) Take a  string field in Tmp table and make enum2str and assign.

Way2) In expressions generally we get for basenums =Fields!BaseenumName.Value now change it to 

Fields!BaseenumLabel.Value 

==> build it and check it.

SSRS report

 To make values empty while opening contract and making last given values empty

code:-

In controller class :-

 protected void prePromptModifyContract()

 {

     super();

     MyContract contract = this.parmReportContract().parmRdpContract() as MyContract;

     if (contract)

     {

         contract.parmFromDate(dateNull());

         contract.parmToDate(dateNull());

         contract.parmPRNumber(null);

     }

 }
