RadOpenFolderDialog generate a lot of exception

[Mathieu]

Just by using that:

            var openFileDialog = new RadOpenFolderDialog();
            openFileDialog.ShowDialog();

 

I get all those exceptions and it break each time I run with the debugger.  It's probably related to my mapped network drives.

The callstack for the first exception:

>mscorlib.dll!System.IO.Path.LegacyNormalizePath(string path, bool fullCheck, int maxPathLength, bool expandShortPaths)Unknown
 mscorlib.dll!System.IO.Path.GetFullPathInternal(string path)Unknown

 Telerik.Windows.Controls.FileDialogs.dll!Telerik.Windows.Controls.FileDialogs.DirectoryBaseWrapper.CanExpand.get()Unknown

 

In RefreshCanExpand not all the exception of EnumerateDirectories seems to be catch.

Hello Mathieu,

Thank you for the shared stack trace.

Those exceptions are thrown and caught with a try-catch structure, in the code of the dialogs, when they try to get an inaccessible directory. They will only be printed in the Output pane of Visual Studio and you can safely ignore them. The application will run properly.

If Visual Studio throws the exception on your side you can disable this by changing the exception settings via the Exception Settings pane. Do give this approach a try and let me know how it goes.
