The actual data type depends on the source control.
// The source control is a grid.
int[] rowHandles = e.Data as int[];
int[] rowHandles1 = e.GetData<int[]>();
// The source is a tree list.
List<TreeListNode> nodeList = e.Data as List<TreeListNode>;
List<TreeListNode> nodeList1 = e.GetData<List<TreeListNode>>();
// The source control is a list box.
List<object> items = e.Data as List<object>;
List<object> items1 = e.GetData<List<object>>();
// If the list box is not bound to a data source (see the Items property),
// the event argument contains string representations of data items.
string item0 = items[0] as string;
// If the list box is bound to a data source (see the DataSource property),
// the actual type depends on the data source.
DataRowView dataRowView0 = items[0] as DataRowView;
