Change datasource for xml and xsd in runtime

Hi

I've a report working with Xml and Xsd, for some reason, I've to create a new "instance" when calling the report, means, create new folder to save the three files: .rpt, .xml and .xsd.

The sample code as following:

            System.Data.DataSet reportData = new System.Data.DataSet();

            reportData.ReadXml(xmlFile);

            ReportDocument reportDoc = newReportDocument();

            reportDoc.Load(rptFile);

            reportDoc.DataSourceConnections[0].SetConnection(xsdFile, "", false);

            reportDoc.SetDataSource(reportData);

The report always uses the initial data (in report design) instead of the new datasource, but the DataSourceConnections updated.

Questions please:

    How to change the data source in runtime?

    How can I check the current data source?

PS.

• Visual Studio 2012
• Crystal Reports for .NET 12.0.2000.0
• C#

Thanks,

Andrew Huang
