The UnPin button which you wish to style is in the AutoHideArea
template (note that there are four such templates - AutoHideAreaLeftTemplate
You can either generate the whole template of RadDocking in Blend and drill down to the PaneHeader_UnPinButtonStyle
in the left auto hide area, or you can use the attached sample. The example uses an implicit style for the left auto hide area, without including all the xaml for the rest of the auto hide areas or the RadDocking style itself.
However, note that to keep your PaneHeader_PinButtonStyle
, you will need to keep your existing customizations.
