It seems that are not supported? or is it a xaml thing I am not aware of (Quite possible)
<igDock:ContentPane Header="abcde_f"></igDock:ContentPane
displays:
abcdef (no underscores)
thanks
In WPF, underscore usually denotes a mnemonic. You can either escape the underscore (by preceding it with an underscore (e.g. "abcde__f"), or you can retemplate the PaneHeaderPresenter such that the ContentPresenter it contains has its RecognizesAccessKey set to false or you can provide your own DataTemplate for the HeaderTemplate (e.g. a TextBlock that binds its Text property).
