C#  Copy Code
public void ExecuteCommand (     Command command )

Visual Basic  Copy Code
Public Sub ExecuteCommand ( _     command As Command _ )

 Parameters

If undo/redo is enabled, the command is saved in the undo history or added to the active composite command.

AddItemCommand and RemoveItemCommand objects are created automatically by the control when adding or removing items, both programmatically or interactively. Calling this method explicitly could be necessary in order to save item's state for later undo using a ChangeItemCommand, or to run a custom operation represented by a class derived from Command.

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
