Catastrophic failure for radcombobox

[Marc]

Hi,
Since I upgraded to the Q3 build, all of my combo's crash when changing the selection.

Unhandled exception, CODE 4004
Catastrophic failure (0x8000FFFF)

The have an ItemSource like:

ObservableCollection<KeyValuePair<SeminarDashboardView, string>>

And are bound like:

<telerikInput:RadComboBox  DisplayMemberPath="Value" SelectedValuePath="Key" SelectedValue="{Binding SelectedView, Mode=TwoWay}"  />

Update: when these combo's are placed on top of a RadWindow, they work just fine. And after having used a combobox on a RadWindow once, the other ones stop crashing. True story.

Is there a problem in the build?
Thanks

Hi, I'm not able to reproduce this problem in an isolated way... It still occurs in my solution, which I can't send over.

We are also encountering "catastrophic failure" in the RadComboBoxes when we try to change the selected value.

I notice that this is happening when we are setting the StyleManager.ApplicationTheme to the the following themes, Office_Blue, Office_Silver, Summer, Vista

example:

Telerik.Windows.Controls.

StyleManager.ApplicationTheme = Telerik.Windows.Controls.ThemeManager.FromName(TelerikTheme.Office_Blue.ToString());

Office_Black is working fine.

We are using the Q32009 release.

Any ideas?

I manage to solve the problem we are encountering.

We are using Prism ( Composite Application Guidance library ).
Whenever we set the ApplicationTheme right after the Shell object is created in the Bootstrapper's CreateShell method, changing the radcomboboxes value that are situated in the Shell.xaml is crashing for Office_Blue, Office_Silver, Summer, Vista ( except Office_Black .. not sure why ).

So moving the setting of the ApplicationTheme right before creating the Shell object fixed the problem.
