Returns

Type Description
T

The data type.

Remarks

The actual data type depends on the source control.

  • For a grid control - an array of row handles.
    // The source control is a grid.
    int[] rowHandles = e.Data as int[];
    int[] rowHandles1 = e.GetData<int[]>();
    
  • For a tree list - a list of the nodes.
    // The source is a tree list.
    List<TreeListNode> nodeList = e.Data as List<TreeListNode>;
    List<TreeListNode> nodeList1 = e.GetData<List<TreeListNode>>();
    
  • For a list box control - a list of the list box items.
    // 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;
