Hi Giorgio,
We would need more information that can help us reproduce or track down this problem. We have the following questions:
Any additional information you could provide that you consider relevant would be highly appreciated.

We would need more information that can help us reproduce or track down this problem. We have the following questions:
- what is your Operating System
- what is your Visual Studio version? If 2008, are you building against .NET2.0 or .NET3.5?
- how big is your project? Scanning for the business objects, uses reflection, so this is time consuming task in general and can take a while on huge projects.
- how much time do you wait for it when it is "frozen"? Have you tried leaving it for a while to see if it would get populated eventually?
- Can you try to bind a winforms DataGridView to your business objects and share the result with us? It uses the same databind wizard, so it would be immediately visible whether this is a problem with our product, VS bug or a problem with your business object.
Any additional information you could provide that you consider relevant would be highly appreciated.
All the best,

VisualStudio 2008 against NET3.5
>how big is your project? Scanning for the business objects, uses reflection, so this is time consuming task in general and can take a >while on huge projects.
Is very small is only a test project 1 form and 1 custom class
>how much time do you wait for it when it is "frozen"? Have you tried leaving it for a while to see if it would get populated eventually?
30 minutes i think was very frozen..... but now this problem is solved
>Can you try to bind a winforms DataGridView to your business objects and share the result with us? It uses the same databind >wizard, so it would be immediately visible whether this is a problem with our product, VS bug or a problem with your business object.
I have try and I can bind a DataGridView without problem
Now VisualStudio do not freeze but when I select my custom data source object i obtainn this message: "DataSet do not support System.Nullable<>"
Where can I find a simple HowTo, to create a simple crosstab report with an object data source?
Thank
Giorgio

I'm having the same issue and have the same environment as Giorgio.
I was able to track down the problem and have found a workaround, however. Here's what I uncovered in the hopes it will help track down the issue.
My Telerik project, using Telerik Q1 2009, contains a set of data objects in a .cs file contained within the Telerik project file. These data objects contain as a property another data object that is exists in another external class library located outside of the Telerik project. This class library is NOT GAC'd and is in a completely different directory than my Telerik project. I simply add a reference to this library in the "References" of my Telerik project and set the properties of that reference to "Copy Local". The project builds without issue.
I then go to my report, which is a simple empty 2009 template and select Data Source | Add Project Data Source... and select the "Data Source Type" as Business Object, VS 2008 hangs and I have to eventually restart it using Task Manager. I have waited as long as 1 hour to see if it would ever come back.
If, however, I take the very same libraries and add their respective projects (.csproj) to my Telerik solution file and reference the projects in the Telerik report project "References", the DataBind wizard finds the data objects and in fact returns very quickly.
Hope this helps.

Hi guys,
Unfortunately even with the steps you provided, we were not able to replicate this on our end. John, I would really appreciate it, if you send us your libraries (or sample ones for that matter), which we can use. Also it is not clear how you add reference in your first case " I simply add a reference to this library in the "References" of my Telerik project and set the properties of that reference to "Copy Local" - do you add reference to the build assembly instead of the project? I've just tried that by creating a new project on my desktop and referenced our CSharp.ReportLibrary from the Visual Studio examples we ship with the reporting installation- business objects worked just fine.
We kindly ask you to open a support ticket and attach sample projects which can be used to reproduce the issue.

Steve

Hi Steve -
I've created a sample project that mirrors in a simple way my project structure and have attached it to a support ticket. This sample project will reproduce the issue that I'm having. The support ticket id: 209380

Hello John,
Thank you for the sample project! We were able to reproduce the freeze, but it is happening very sporadically i.e. 1 out of 5 times, so we would need more time to investigate what is the exact culprit behind this. We would post in your ticket and here once we have more info.
Thank you for the involvement once again!
Kind regards,

Steve,
I have the same problem. In my case it freezes 5 out o 5 times.(thus,all the time)
After 15mins I've had to kill vs.net 2008.
I must say that in my classes there are several circular references.
Maybe that's somehow related ?
My info : windows vista bussiness + SP2 + Intel core 2 duo 2,5Mhz.

Hi Sebastian,
We've already found the culprit for this problem and it would be part of the next Telerik Reporting version. To be on the safe side, you can try binding a datagrid or asp:repeater with your class and if they bind ok (i.e. no problems whatsoever) then it is the same problem we've tackled with.
Please excuse us for the temporary inconvenience.
Best wishes,

We have run into the same issue as described above and was wondering if Telerik was able to release a fix as a hot fix or as part of a published internal build?

Hello Jim,
We have not released a fix for this issue yet. The official Q2 release is scheduled for the end of June.

Thanks for the fast response. Is there any chance you will publish an internal build with this fix before June? We are using a single instance of Telerik ORM for both our reporting layer and our UI. I do not really want to have to create two data layers just to work around an issue like this.
Thanks again!
Thanks again!

Hi Jim,
We have not released internal builds for the reporting product so far and this would slow us down for the official release. We would see if we can a good built and try to post it, but we cannot engage with a time frame and of course this build would not be recommended for production environments as we do not do extensive tests on such builds. I will update this thread if we manage to get an internal build available before the release.
Sincerely yours,
Steve
