ReportParameter.ValidValues

I have been assigned to create a new report subscription form. I have
done everything but prompt the user for values. So there are a bunch
of reports with varied parameters. Some of these parameters are
hard-coded lists and others are DataSetReference. How do I provide the
subscriber with an accurate list of valid values?
I was thinking something like:
ReportParameters[0].reportParameter.ValidValues
but that comes back null.
I tried reportService.GetReportParameters(report, historyID,
forRendering, values, credentials)
Values comes back null.
Please help!
Thank you!
--Larry--"values" in GetReportParameters is used to validate parameter values.
Actual parameters are returned by GetReportParameters.
You can try something like this:
ReportParameter [ ] rp = reportService.GetReportParameters(report,
forRendering, historyID, null, credentials);
rp[0].ValidValues should contain valid values.

>|||Thank you, but that didn't work,
The ValidValues is <undefined value>
I used the following code:
ValidValue[] vv = new ValidValue[0];
parameters = server.GetReportParameters(thisfolder, null, false,
Paramvalues, Paramcredentials);
if (parameters.Length != 0)
{
vv = parameters[0].ValidValues;
}
when I look at parameter[0] (and 1 as well) I have ValidValues
<undefined value>
CalidValuesQueryBased = true
ValidValuesQueryBasedSpecified = true|||Thank you, but that didn't work,

post:
If ForRendering has a value of false, the parameter meta data returned
represents the parameter data that is currently associated with the
specified report. If any parameters values are based on a query and you
are
interested in returning the query-based parameters valid values list,
you
need to set ForRendering to true, In addition, for query based
parameters,
you need to ensure that you have passed in all of the credential
information
required to return the query parameters.
I set this parm to true and got my values!!
