JScript prend en charge l'utilisation d'événements mais pas la déclaration de nouveaux événements.
ExemplePrivate Sub DataTableRowChanged() Dim custTable As DataTable = New DataTable("Customers") ' add columns custTable.Columns.Add("id", Type.GetType("System.Int32")) custTable.Columns.Add("name", Type.GetType("System.String")) custTable.Columns.Add("address", Type.GetType("System.String")) ' set PrimaryKey custTable.Columns("id").Unique = True custTable.PrimaryKey = New DataColumn() {custTable.Columns("id")} ' add a RowChanged event handler for the table. AddHandler custTable.RowChanged, _ New DataRowChangeEventHandler(AddressOf Row_Changed) ' add ten rows Dim id As Integer For id = 1 To 10 custTable.Rows.Add( _ New Object() {id, String.Format("customer{0}", id), _ String.Format("address{0}", id)}) Next custTable.AcceptChanges() ' change the name column in all the rows Dim row As DataRow For Each row In custTable.Rows row("name") = String.Format("vip{0}", row("id")) Next End Sub Private Sub Row_Changed(ByVal sender As Object, _ ByVal e As DataRowChangeEventArgs) Console.WriteLine("Row_Changed Event: name={0}; action={1}", _ e.Row("name"), e.Action) End Sub
private static void DataTableRowChanged() { DataTable custTable = new DataTable("Customers"); // add columns custTable.Columns.Add("id", typeof(int)); custTable.Columns.Add("name", typeof(string)); custTable.Columns.Add("address", typeof(string)); // set PrimaryKey custTable.Columns[ "id" ].Unique = true; custTable.PrimaryKey = new DataColumn[] { custTable.Columns["id"] }; // add a RowChanged event handler for the table. custTable.RowChanged += new DataRowChangeEventHandler(Row_Changed); // add ten rows for(int id=1; id<=10; id++) { custTable.Rows.Add( new object[] { id, string.Format("customer{0}", id), string.Format("address{0}", id) }); } custTable.AcceptChanges(); // change the name column in all the rows foreach(DataRow row in custTable.Rows) { row["name"] = string.Format("vip{0}", row["id"]); } } private static void Row_Changed(object sender, DataRowChangeEventArgs e) { Console.WriteLine("Row_Changed Event: name={0}; action={1}", e.Row["name"], e.Action); }
