BindingFailure was detected

[Pierre Alain]

We recently updated to Q1 2010 SP2.

When I add a office2007BlackTheme to a form, the run in debug with Exceptions set up to break whenever an exception is thrown, I get the exception below on this line from InitializeComponent:

 

 

this.office2007BlackTheme1 = new Telerik.WinControls.Themes.Office2007BlackTheme();

 

 

 

Everything still seems to work fine, but it is anoying when debugging.

Hi pacarrier,

The issue that you experience seems to be related to an assembly mismatch. Please make sure that you have followed all the steps described in this article concerning the upgrade process.

If you have additional questions, feel free to contact me.

Thank you for your reply.

I updated using the Project Upgrade Utility.

Please note that if I create a new project from scratch, I get the same result.

The reference seems to be correct: C:\Program Files\Telerik\RadControls for WinForms Q1 2010 SP2\bin\Telerik.WinControls.Themes.Office2007Black.dll. Version is 2010.1.10.504. From the debug console, I can see that assembly loading fine.

I can't find Telerik.WinControls.XmlSerializers anywhere. Where is it supposed to be?

Found this bug report on Microsoft Connect: https://connect.microsoft.com/VisualStudio/feedback/details/304095/bindingfailure-mda-when-using-xmlserializer

The solution would be to use sgen for whatever xmlserialiable type is used in that assembly.

For now, I'll turn off Exceptions...

Hello pacarrier,

Thank you for writing and for the research you have done.

Indeed, this is just how the xml serializer works. There are other instances of similar behavior. For example if CurrencyManager calls a part of your code and you throw a particular exception it will catch it and the debugger will stop if you have enabled the .NET Framework source stepping. This can be a huge pain when your have many controls bound to the same data source but this is how it works.
Also, the approach with exception handling is not necessarily wrong. After all, the exceptions were created in order to avoid if statements and functions returning error codes. An exception being thrown also does not always mean an error.

This particular exception can be really annoying when debugging serialization of hundreds objects, but this is how Microsoft decided to implement it.

Please write again if you have other questions or if you need assistance with our controls.
