DataView.AllowNew 屬性


取得或設定值,指出是否可以使用 AddNew() 方法加入新的資料列。Gets or sets a value that indicates whether the new rows can be added by using the AddNew() method.

 property bool AllowNew { bool get(); void set(bool value); };
public bool AllowNew { get; set; }
member this.AllowNew : bool with get, set
Public Property AllowNew As Boolean


如果可以加入新的資料列,則為 true,否則為 falsetrue, if new rows can be added; otherwise, false.



下列範例會先將AllowNew屬性設定為 true, 然後再AddNew使用方法加入新的資料列。The following example sets the AllowNew property to true before adding a new row with the AddNew method.

private void AddNew()
    DataTable table = new DataTable();

    // Not shown: code to populate DataTable.

    DataView view = new DataView(table);
    view.AllowNew = true;
    DataRowView rowView = view.AddNew();
    rowView["ProductName"] = "New Product Name";
Private Sub AddNew()
    Dim table As New DataTable()

    ' Not shown: code to populate DataTable.

    Dim view As New DataView(table)
    view.AllowNew = True
    Dim rowView As DataRowView
    rowView = view.AddNew
    rowView("ProductName") = "New Product Name"
End Sub
