but when I deploy it to the web server I this error

Dim reportUri = New Uri("/Arrangement/Arr_Bekraeft.igr", UriKind.Relative)
Dim Exporter = ServerExporterFactory.CreateExporter(reportUri)
Dim Param As New List(Of Infragistics.Reports.ParameterValue)
Dim P1 As New Infragistics.Reports.ParameterValue()
P1.Name = "ID"
P1.Value = ID
Param.Add(P1)
Exporter.Parameters = Param
Dim FilStream As New FileStream(Filnavn, FileMode.Create)
Exporter.Export(FilStream, "PDF")
FilStream.Close()

Thanks, Hector.

1. No, that is not possible. The idea is to either use the DataSources property, or use the DB connection provider to override the connection details.

2., 3. There are no online examples, but the properties are straightfoward to use:

var uri = new Uri("ProgrammaticExportWithRuntimeDataSources;component/Report1.igr", UriKind.Relative);

using (var exporter = ServerExporterFactory.CreateExporter(uri))

{

    using (var fs = new System.IO.FileStream(@"c:\temp\igsalesreport.pdf"))

    {

        var dataSources = new List();

        dataSources.Add(

            new DataSourceValue

            {

                Name = "Data Source Name",

                Value = /* IEnumerable that contains the data */

            });

        exporter.DataSources = dataSources;

        var parameters = new List();

        parameters.Add(

            new ParameterValue

            {

                Name = "Parameter Name",

                Value = /* Parameter Value */

            });

        exporter.Parameters = parameters;

        exporter.Export(fs, "PDF");

    }

}

I was able to do this by implementing IReportDbConnectionProvider (below).  But that just leads to more questions

1.  Can I access the Sql stored in the report and update it on the fly?

2.  IServerExporter.DataSources - is there an example of adding one?

3.  IServerExporter.Parameters - again, is thaere an example of this being used?  Google is failing me.

Thanks

Joe
