Attached Behaviors

The Acitpro WPF DataGrid Contrib assembly includes attached behaviors, which are described in this topic.

FocusBehavior

This class provides attached behavior for DataGrid controls to track the focus, which is configured by setting the FocusBehavior.TrackingModesProperty attached property to one or more values from the FocusTrackingModes enumeration.

Column Header

When FocusBehavior.TrackingModesProperty includes the Headers enumeration flag, then the read-only FocusBehavior.IsFocusedHeaderProperty attached property will be tracked/maintained. This allows one or more triggers to alter the look of the column headers when one of the associated cells has focus.

NewRowTemplateBehavior

This class provides attached behavior for DataGrid controls to customize the new row template. The NewRowTemplateBehavior.TemplateProperty attached property can be set to a custom ControlTemplate to use when the new row is not currently editing.

By default, the new row looks identical to actual data rows, but with empty cells. Using NewRowTemplateBehavior, a more appealling look can easily be achieved.

SelectionBehavior

This class provides attached behavior for DataGrid controls to track the selection, which is configured by setting the SelectionBehavior.TrackingModesProperty attached property to one or more values from the SelectionTrackingModes enumeration.

Column Header

When SelectionBehavior.TrackingModesProperty includes the Headers enumeration flag, then the read-only SelectionBehavior.IsSelectedHeaderProperty attached property will be tracked/maintained. This allows one or more triggers to alter the look of the column headers when one or more of the associated cells is selected.
