// object's selection state.

// (1) The IsSelected property is dynamically injected into
// DataTable when object data is read from database.
// See ReadRawData() function in the
// IS3.Core.Serialization.DbDataLoader class for more information.
// (2) The DataTable is used to display object data in
// the datagrid (class IS3DataGrid). When IsSelected property
// is set to true, it will be displayed as selected state
// in the datagrid.
