Crystal DiscardSavedData() method in C#

I am writing a c# program that loads a report into the Crytsal viewer and displays it on a form.
I want to be able to invoke the DiscardSavedData method to force the report to always do a new query.
I understand that this is a method of the report object but the intelisense in VS 2005 doesn't show the method

I am using VS 2005 with Crystal XI.

my code is like this
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
public bool SetReportName(string strReportName)
{
bool bRes=false;
m_ReportName=strReportName;
m_oRpt = new ReportDocument();
try
{
m_oRpt.Load(m_ReportName);
bRes=true;
}
catch (Exception e)
{
MessageBox.Show(e.Message);
return bRes;
}
return bRes;
}

'''''''''''''''''''''''''''''''''''''''''''''''''''''''
Elsewhere in the project I show the form and populate the viewer with the report ibject
// set the viewer source that actually displays the report
cvf.crystalReportViewer1.ReportSource = m_oRpt;

I was expecting to be able to do m_oRpt.DiscardSavedData() but the method isn't available.
I suspect that I am using the incorrect ReportDocument type but all the examples I have seen use this technique.
Can anyone advise please?

Thanks

Check if it is on the viewer object.

Did you try just typing it in?

Are you using CR XI or the Crystal that comes with VS?  If it is the standalone version did you update to Release 2 of CR XI?

Thanks for the reply.
I am using Crystal XI and it is updated to Crystal SP2.

I tried just typing the method in and ignoring the fact that it wasn't in the intellisense but when the project was built I got an error about an unsupported method.

I am assuming that whilst I have Crystal XI on the system it will have overwritten any components that VS2005 would have come with with the ones from SP2.

Do you have an example of this method being used in a C# program - if I could compare a working sample with my code I might be able to work out what is going on?

Thanks

Hi mimmc,
I did some more browsing on the Business Objects site and there are other downloads specifically for Crystal XI and c# - thanks for pointing me in the right direction

try to use the following command
rptDoc.ReportOptions.EnableSaveDataWithReport = False
where rptDoc is Reportdocument

@mlmcc: the link above just takes me to a SAP main page, no specific examples in C#. can you post some links with specific examples?
