Metadata properties set to true
When the property is set to true, a preview of the change in the row or column sizes is shown. The actual size changes when the GridSplitter is released. If the property is set to false, the column or row sizes are updated in real time as the user drags the GridSplitter control.
If the keyboard is used to move the GridSplitter control, column or row sizes are updated in real time even if the property is set to true.
A GridSplitter requires an AdornerDecorator object to be present in its parent tree in order to display drag preview feedback. This requirement is typically met by the AdornerDecorator object that is available in the default style for the Window or in the AdornerDecorator object that is created by a ScrollViewer object. However, if neither of these is available, the GridSplitter control must define its own AdornerDecorator object.
