I have developed a custom report item that works fine in design and preview mode while in Visual Studio. I cannot get it to show up on my deployed reports. Here's what I have done so far: 1. Deployed the report using Visual Studio 2. updated the rsreportserver.config file with the following entry: <ReportItems> <ReportItem Name="PedigreeChart" Type="Uabr.Rap.PedigreeChart.PedigreeChartRenderer, Uabr.Rap.PedigreeChart" /> </ReportItems> 3. Updated the rssrvpolicy.config file with the following entry. <CodeGroup class="UnionCodeGroup" version="1" PermissionSetName="FullTrust" Description="This code group grants Uabr.Rap.PedigreeChart.dll FUllTrust permission. "> <IMembershipCondition class="UrlMembershipCondition" version="1" Url="C:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer\bin\Uabr.Rap.PedigreeChart.dll" /> </CodeGroup> I've also tried using the StrongNameMembershipCondition with no better results. 4. The dll and its dependencies are copied to the bin directory of the report server. 5. When I load a report with this custom report item on it, the report loads fine with no errors or warnings in the log file (even with verbose tracing). The area where the custom item should be is just white. It's almost like Reporting Services isn't registering the item correctly. This is particularly frustrating because the report works fine in Visual Studio - apparently I configured that correctly.Any suggestions would be greatly appreciated. I'm stumped.

Hello, I'm having the exact same problem that you describe. I am also stumped and was wondering if you've found a solution to this problem? Thanks

I got it working, but I'm honestly not sure what I did to get it to work. I ended up granting all assemblies on the server fulltrust, which wasn't my preference but seemed to take care of the issue. However I'm still not sure if that was the item that fixed things. What I am sure about was that is was some configuration issue and not an assembly problem in my case because all I did was srcrew with the configuration for a while. It was a frustrating experience and I'm sorry I can't help more.

Hi, I hab the same problem in the beginning. What solved it for me was that ALL assemblies being used by the CRI have to be trusted, including unmanaged C++ DLLs if there are any. First I listed each DLL but then I gave all my DLLs a strong name and now it works with only the strong name membership condition. For debugging I enabled something named like 'assembly load logging' on the local report server. I also tried attaching to the worker process in order to read the debugging messages in VS if I remember that right. Hth, Thomas

Did anyone find a custom report item sample/tutorial/example with VB.NET? I'm getting reference and compiler errors attempting to use the C# progress bar example.
