Make internal and private getter in DataGridCell public #186
Description
What is the reason, why the getters of IsCurrent, IsEdited, IsMouseOver, RowIndex, ColumnIndex... are internal or private?
This prevents the implementation of custom DataGridBoundColumn's.
Furthermore, there's no way to query external classes to determine which cell is currently focused. WPF used CurrentCell for this purpose. This property doesn't exist here, and EditingRow is internal. In general, there are too many restrictions regarding public read access to non-critical properties.
