Syntax

C# Copy Code
public class ChangeItemCommand : Command

Visual Basic Copy Code
Public Class ChangeItemCommand Inherits Command

The ChangeItemCommand constructor records the state of an item, and its Undo and Redo methods restore the item to either its old or new state.

The following example shows the pattern that should be used to save the state of an item for later undo.

C# Copy Code
Item item = calendar.ItemSelection.Items[0]; if (item != null) { ChangeItemCommand change = new ChangeItemCommand(calendar.Schedule, item); item.HeaderText = "new header"; item.StartTime = DateTime.Now; item.EndTime = DateTime.Now.AddHours(2); calendar.Schedule.ExecuteCommand(change); }

Visual Basic Copy Code
Dim item = calendar.ItemSelection.Items(0) If (item IsNot Nothing) Then Dim change As New ChangeItemCommand(calendar.Schedule, item) item.HeaderText = "new header" item.StartTime = DateTime.Now item.EndTime = DateTime.Now.AddHours(2) calendar.Schedule.ExecuteCommand(change) End If
