Hi Experts,

I am trying to add a validation in my SSRS report's contract class to make sure the dates are selected properly. Below is my contract class and the methods in it. The validation is not working (Nothing happens when I select an invalid period) when I run the report ,can anyone help me with if I missed anything or what's wrong in it.

class XYZ implements SysOperationValidatable
{
TransDate FromDate,ToDate;
}

[DataMemberAttribute('From Date'),SysOperationLabelAttribute('From date :'),SysOperationDisplayOrderAttribute('1')]

public TransDate parmFromDate(TransDate _fromDate = FromDate)
{
FromDate = _fromDate;
return FromDate;
}

[DataMemberAttribute('To Date'),SysOperationLabelAttribute('To date :'),SysOperationDisplayOrderAttribute('2')]

public TransDate parmToDate(TransDate _toDate = ToDate)
{
ToDate = _toDate;
return ToDate;

}

public boolean validate()
{
boolean IsValid = true;

if (!FromDate || !ToDate || ToDate < FromDate)
IsValid = checkFailed("Invalid Date");

return IsValid;
}

Is your class really missing DataContract attribute, or did you merely share incomplete code?

By the way, please always use Insert > Insert Code (in the rich formatting view) to paste source code. It preserves line indentation, which makes code much easier to read.

What did you find when you debugged your code before giving it up and coming here? Does validate() get called at all?

By the way, you again forgot to use Insert > Insert Code. This is how it would look like:

[DataContractAttribute] class XYZ implements SysOperationValidatable { TransDate fromDate, toDate; [ DataMemberAttribute('FromDate'), SysOperationLabelAttribute('From date:'), SysOperationDisplayOrderAttribute('1') ] public TransDate parmFromDate(TransDate _fromDate = fromDate) { fromDate = _fromDate; return fromDate; } [ DataMemberAttribute('ToDate'), SysOperationLabelAttribute('To date:'), SysOperationDisplayOrderAttribute('2') ] public TransDate parmToDate(TransDate _toDate = toDate) { toDate = _toDate; return toDate; } public boolean validate() { boolean isValid = true; if (!fromDate || !toDate || toDate < fromDate) { isValid = checkFailed("Invalid Date"); } return isValid; } }

I've also fixed a few things in your code.

Try to print or debug the parameters(from date , To date) in the DP class to make sure your contract class working fine.
