Hello dear Support,
i evaluate the Devexpress WpF Controls and i try to use the controls programmatically.
The programmatically use of a couple of already tested devexpress controls works fine.
If I try to use the DXTabControl as in the attachment (constructor of the Class MainWindow), a System.Security.VerificationException occures adding the TabItem to the Control.
Can you please help me and give me a hint what i do wrong?
Thank you very much!
Gianpietro Dal Zio

Hello,
I suggest that you uncomment out the InitializeComponents method, you code will work fine:
public MainWindow() { InitializeComponent(); Grid wholeWindowContentGrid = new Grid(); DXTabControl tabControl = new DXTabControl(); tabControl.View = new TabControlScrollView(); DXTabItem tabItem = new DXTabItem(); tabItem.Header = "Header of the tab item"; Grid tabItemContentGrid = new Grid(); Label testLabel = new Label(); testLabel.Content = "asdfadfadfadsfadsfasdfsadf"; tabItemContentGrid.Children.Add(testLabel); tabItem.Content = tabItemContentGrid; tabControl.Items.Add(tabItem); wholeWindowContentGrid.Children.Add(tabControl); this.Content = wholeWindowContentGrid; }I've attached the modified sample.
Thank you, Marina
Hi Marina,
thank you for your reply.
Uncommenting the InitializeComponent() call does not solve the error.
The workaround for me is to create a local administrator account (without Domain authentication).
I investigate that the error occures only when i try to debug the Application with Visual Studio.
If i run the content of the "build" directory the DXGridControl works fine…
The preview im VisualStudio WpF WYSIWIG works fine too…
Maybe are the problems specific to our domain security policies ?!
Thank you for your help…

Giapietro
Hello Giapietro,
>The workaround for me is to create a local administrator account (without Domain authentication).
Sorry, we are not aware of how this can affect the WPF application with custom libraries. Our libraries don't have any special settings. I believe that you have some special settings on your OS, and this problem can be reproduced with any custom libraries. If you need further assistance, please clarify your OS settings, so our developers can research the issue.
Thank you, Marina
Hi,
i found the problem.
The postet error occurres if the Setting Tools->Options->IntelliTrace->General->"Intellitrace events and call information" ist enabled. (See screenshot).
The setting "Intellitrace events only" does not produce the error…
Gianpietro
Hello Gianpietro,
Thank you for your feedback. Your post can be very helpful for other users. As far as I know, the Intellitrace option is only available for the VS2010 Ultimate edition. This exception is not visible at runtime, since it is caught and properly handled. We recommend that you just skip this exception, as it does not break anything in the working application.
Thank you, Marina
Hi,
the problem exist in Build 1.5.1 too.
If someone needs to use all the features of Intellitrace (Setting "Intellitrace evants and call information") it is necessary to exclude the module "DevExpress.Xpf.Core.DXTabControl" from collecting, this can be done under VS Options->Intellitrace->Modules…
I hope this can be helpful for someone…
