Custom RadMap Provider for Q1 2011
Since Q1 2011 and the newest release of the RadMap several changes were made to the control.

RadControls for WPF, 2011.Q1 We will start with the project from the previous post: DOWNLOAD: RadScheduleView_GroupHeaderTemplates.zip And will produce the following project that has its timeruler items modified: DOWNLOAD: RadScheduleView_TimeRulerItemTemplates.zip Using the GroupHeaderContentTemplateSelector you can bind to the resource data.

TimeRulerItems and GroupHeaders in RadScheduleView
RadControls for WPF, 2011.Q1 The most important controls in RadScheduleView are the GroupHeaders, AppointmentItems and TimeRulerItems.
