Class GridVirtualizingCellRenderer<D, E>
GridVirtualizingCellRenderer is an abstract base class for cell renderers
that need live UIElement visuals displayed in a cell. You can derive from
this class and provide the type of the UIElement you want to show inside cells
as type parameter. The class provides strong typed virtual methods for
initializing content of the cell and arranging the cell visuals. See
The idea behind this class is to provide a place where we can add general code that should be shared for all cell renderers in the tree derived from GridVirtualizingCellRendererBase. While this class does at the moment not add meaningful functionality to GridVirtualizingCellRendererBase we created this extra layer of inheritance to make it easy to share code for the GridVirtualizingCellRendererBase base class between grid and common assemblies and keep grid control specific code out of the base class. It is currently not possible with C# to the base class as template type parameter.
