Hello,

I get an error in DataContext when running a report. In designtime the preview works fine but in runtime the error in DataContext popups with the following stacktrace:

Infragistics.Reports.Engine.EngineException: Error in DataContext =DataSources.sqlDataSourceSalesWeb. ---> Infragistics.Reports.Engine.Data.EngineDataException: Error in DataContext sqlDataSourceSalesWeb. ---> Infragistics.Reports.Engine.Data.ConnectionStringNotFoundException: Exception of type 'Infragistics.Reports.Engine.Data.ConnectionStringNotFoundException' was thrown.    at Infragistics.Reports.Engine.Data.QueryHelper.RunQuery[T](String dataProvider, String connectionString, Query query, IDictionary`2 parameterValues, Func`2 action, CommandBehavior behavior, DbConnection customDbConnection)    at Infragistics.Reports.Engine.Data.SqlReportDataProvider.Execute()    at Infragistics.Reports.Engine.Data.ReportDataSourceManager.GetReportDataSource(DataSource reportDataSource)    --- End of inner exception stack trace ---    at Infragistics.Reports.Engine.Data.ReportDataSourceManager.GetReportDataSource(DataSource reportDataSource)    at Infragistics.Reports.Expressions.RuntimeEvaluationContext.<>c__DisplayClass2.<AddDataSource>b__1()    at Infragistics.Reports.Expressions.EvaluatorHelper.Accessor(Object target, String propertyName, Boolean onParent, Boolean scaleUp)    at lambda_method(Closure , IRuntimeEvaluationContext )    at Infragistics.Reports.Expressions.EvaluatorVisitor.Evaluate(Expression expression)    --- End of inner exception stack trace --- An error occurred while binding an expression.

The XAML of the reportviewer is:

        <ig:XamReportViewer Grid.Row="1" Margin="12,12,12,43" Name="xamReportViewer">
            <ig:XamReportViewer.RenderSettings>
                <ig:ClientRenderSettings DefinitionUri="/SalesWeb.Sales;component/Reports/OrderConfirmation.igr" />
            </ig:XamReportViewer.RenderSettings>
        </ig:XamReportViewer>

Nothing is done in code behind to change the datasource or something.

What is it that I am doing wrong?

Thanks for any assitance.
