Exception: "System.Windows.Documents.Hyperlink" is not a "Visual" or "Visual3D."

[Maksim Gladkov]

Good afternoon,

We started getting this exception on one of our forms, after upgrading Telerik control for WPF to a new version.
The exception occurs for a DataGridHyperlinkColumn of the DataGrid in the RadTabControl.
Can anyone help us with this?

Stack trace:

Hi Maksim,

We haven't encountered nor seen this exception before. Can you try to isolate it in a sample project and send it over so that we can investigate the cause on our side? Thank you in advance.
