This is a quick sample that collapses the header of the Content Pane in the XamDockManager.  I share it here, as I recently had a customer ask how to do this, and I hope this sample might be helpful to others.

The Style targeting ig:ContentPane is copied from the default styles folder installed with NetAdvantage into the sample Window's resources.  The PaneHeaderPresenter's Visibility is set to "Collapsed" and this Style is assigned a Key so that it is applied selectively to those Content Panes requiring it.
