// DataRows in the this DataTable's DataRowCollection;
// this index is really a cache that gets
// created during Open(), gets Updated
// when various properties of this view
// changes, gets Updated when this DataTable's
// row, column, or constraint collections have changed.
// I'm not sure what else.
// The data view will know one of the DataTable's
// collections have changed via one of
// its changed events.
// Otherwise, if getting a/the DataRowView(s),
// Count, or other properties, then just use the
// index cache.
