How to create a custom render extension in SSRS 2008.

Question

Hi,

Please let me know that how can I create a custom render extension in SSRS 2008. I have created it in SSRS 2005, but when I try using the same code in SQL Serever 2008, it does not work. The IRenderingExtension interface doesnot seem to be compatible with 2008.

It gives the following compilation error:

Class 'Renderer' must implement 'Function Render(report As Report, reportServerParameters As System.Collections.Specialized.NameValueCollection, deviceInfo As System.Collections.Specialized.NameValueCollection, clientCapabilities As System.Collections.Specialized.NameValueCollection, ByRef renderProperties As System.Collections.Hashtable, createAndRegisterStream As Interfaces.CreateAndRegisterStream) As Boolean' for interface 'Microsoft.ReportingServices.OnDemandReportRendering.IRenderingExtension'.

Please help..........

The name space for IRenderingExtension has changed from Microsoft.ReportingServices.ReportRendering (2005) to Microsoft.ReportingServices.OnDemandReportRendering in 2008.
