I have the wpf report viewer in a user control which is on a tab (Telerik RadTabControl). When I close the tab I get
the following exception:

System.NullReferenceException was unhandled
Message=Object reference not set to an instance of an object.
Source=Telerik.ReportViewer.Wpf

Hello Claus,

In v. 5.3.12.119 we have not built against the latest WPF controls version, so if you have referenced RadControls for WPF Q3 SP1, you should add binding redirects in order for the viewer to function correctly. For more information refer to How to: Add report viewer to a WPF application Binding Redirects section. If the problem persists, please open a support ticket and attach a sample project that exhibits the problem so we can look into it locally.

All the best,
Steve

I recently tried this by adding these lines into my config file and it does not fix the issue. The issue still remains.

I'm going to have to request an internal build if possible. We are between a rock and a hard place on this issue.

The previous version has multiple issues with it (page numbering problems, missing tool tips on buttons, inability to change document rendering message). So it is inadequate for us. We only continued to use it because we were promised fixes for our issues in the next version.

When we updated to the next version, we didn't notice right away that Telerik had introduced a fatal exception. So development on reports continued on the 5.3.12.119 version.

We've since rolled back our Telerik Reporting assemblies (dlls) and have uninstalled the 5.3.12.119 version from our machines and reinstalled the 5.3.11.1116 version. However, none of our reports can be loaded in the designer now. Every one of them throws an exception (despite us manually changing the version stored in each report back). Therefore we cannnot continue work on our reports. We could try rolling back our reports to an earlier time, but then we will lose a couple of months of work. We have about 1 month before our application is scheduled to be released to the public and don't have the time or resources to redo the work or remake the reports.

We need some immediate solution to resolve this issue!

Edit: I fixed my mistyping of the previous version.

I do not see a 5.3.11.1119 version, you probably talk about the Q3 (5.3.11.1116). Problems with the designer not opening after changing versions is usually caused by improper upgrade or so I've noticed from experience. Go into your solution and delete manually reporting dlls, then re-add the references to the desired version. The Upgrade Wizard (http://www.telerik.com/help/reporting/ui-upgrade-wizard.html) does update the references, but any manually copied dlls would have to be deleted. Ah, and don't forget to rebuild!

While the bug in the current version is bad, I do not think starting a flame and complaining about everything including not being able to revert to previous version you had working is in your favor. After all it used to work for you, right?, readding references and rebuilding your project would have probably been faster than posting a reply.

Good luck!

Yes, I mistyped. I meant to type 5.3.11.1116 for the previous version.

I have replaced all the manually referenced dlls. We have rebuilt the project. The reports still throw exceptions when trying to load then in the designer.

I wasn't starting a flame. I'm not sure why you'd accuse me of that as if that was my intention. I was explaining a real world situation that we have unexpectedly run into and trying to convey my level of concern. I was seeking help.

I don't understand why you made the comment that posting was a waste of my time, that it would have been better spent re-adding references and rebuilding. That is something we already attempted and it did not work. Your assumption that it has to work is some what presumptuous, right? After all, the previous post about Binding redirects did not resolve any one else's issue either.

As far as it "used to work for us", it did. But on versions of the reports that are much older. If I return to those working versions, I am going lose a lot of valuable work. I'm on a tight deadline with limited resources and I'd much rather have a solution that doesn't involve me recreating a month's worth of report changes. And it's not as if I'm still not attempting to isolate the issue to prevent losing the work. But you can understand why I might appreciate a solution from Telerik as opposed to me spending my time when I could be working on some other outstanding issue in our application can't you? Especially when you consider that your customer's didn't create the bug in the viewer, Telerik did.

I've gone back and re-read my earlier post many times now and I'm still at a loss as to why you would accuse me of trying to start a flame. I tried to see exactly what it was I was complaining about, as you put it, but I only see myself as explaining the situation I was in. My hope was if anyone else here on the thread had run into similar issues, that they could share how they resolved them (isn't that the point of a forum?). And if they weren't able to resolve them, possibly garner support by allowing others to express their concerns as to why they would prefer a more immediate resolution as opposed to waiting 2-3 more weeks. I fail to see why I was deserving of the accusatory remarks against my intentions.

I have tried the internal build and it does fix most of our problems. But like so often, it also introduces a new problem.

We are using a custom theme for the Wpf ReportViewer. It references a class called ZoomConverter. It throws an error trying to instantiate ZoomConverter. This is the error:

<Message
