Exception thrown in design mode

[Jason]

Hi,

I've just installed Telerik Report Q1 2009, and now I'm having this problem.

In visual studio, I added a new item of Telerik Report Q1 2009 in my project. I could see the auto-generated code in Code mode, but when I switched to the design mode, it threw an exception on the opened design mode page, which said: Object reference not set to an instance of and object. In addition, when I run the Telerik Reporting Q1 2009 Demo Application, click one of the nodes in the left tree,say, Sales Dashboard, an error window pop up showing:

Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.
Exception has been thrown by the target of an invocation.

When I clicked the "Details" button, it shows following details:
/*---------------------------------------------------------------------------------------------------------------------------------------------*/

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

My OS is windows XP professional SP3. But in my colleage's computer, which is Windows server 2003, there is no such problem.

Hello Jason,

This is a known issue that slipped into the Q1 SP1 release, for which we sincerely apologize. The bug can occur when the current desktop DPI setting is different from 96 DPI (or you have a custom windows font set), and the ReportViewer tries to auto-scale itself accordingly. The issue has already been addressed and would be part of the subsequent Telerik Reporting release. As a temporary work-around you can reset your desktop DPI setting to 96 DPI (or return to default font).

Please, excuse us for the temporary inconvenience.

All the best,
Steve

Hi Steve,
Thanks for your quick reply. However, after I checked my desktop setting, I found it was 96DPI. I have never changed anything about this and windows font set. So is it because of something else?
Thanks!

[Steve]

Hi Jason,

As explained in my previous reply, the issue occurs with different windows fonts as well. So in your case, if your windows is localized (i.e. Chinese windows), then the font used is not the standard and the report viewer would always try to auto re-size, thus throw the error. Unfortunately in this case there is no workaround other then reverting back to v.Q1 2009 which does not exhibit this problem.

Please excuse us for the inconvenience.

Kind regards,
Steve

Thanks Steve, yes, my OS is Chinese windows. But, one of my colleagues has installed in his computer, which is with Windows Server 2003, and the program runs fine. His OS is also Chinese windows.

Hello Jason,

Well, I guess the font of the windows 2003 server differs from the font of the Vista/XP windows. Either way there is no other workaround at the moment for localized windows except reverting back to the previous version (link is available in my previous post).
We have taken precautions from now on to test on localized and OS with different dpi to avoid such unpleasant problems in the future. As explained the issue is already fixed and would be part of the Q2 release expected in the end of June.

We sincerely apologize once again for the inconvenience caused.

Best wishes,
Steve

Thanks, Steve. Now we just use the Q1 2009 version first, and everything is ok now.
