Upgrading Telerik reports Q3 2009 to the latest version

[Ashwini]

I have a lot of reports developed using Q3 2009 version of telerik reporting. Before developing new reports, we want to ensure that the existing reports work as they used to after upgrading to latest version of telerik reporting. But all the reports which use subreport fail compilation with the error: 'DataItem' is not a member of 'Telerik.Reporting.Processing.SubReport'.

All the reports use objectdatasource.

 

 

 

 

 

Private Sub SubReport1_NeedDataSource(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SubReport1.NeedDataSource

 

 

 

Dim subReport As Telerik.Reporting.Processing.SubReport = DirectCast(sender, Telerik.Reporting.Processing.SubReport)

 

subReport.InnerReport.DataSource =

 

DirectCast(subReport.DataItem, System.Data.DataRowView)("subreportList")

 

 

 

End Sub

Please suggest what needs to be done here so that I can quickly fix these existing reports and then move to development of new reports

Thanks in advance

Hi Ashwini,

This API change has been introduced long ago and should you have upgraded in a shorter period of time, you would have received warnings upon compile, that it is obsolete and what you should use instead. Since you upgrade from a version that is 3 years old, the DataItem property is long gone and you do not get any warnings for this reason. To get your reports up and running, please follow the instructions from the following KB article: ReportItemBase.DataItem property (Telerik.Reporting.Processing) has been replaced by property DataObject.
