Undo and Redo an Action in a Text Box or a Combo Box

The following example demonstrates how to undo or redo text editing within a TextBox or within the text area of a ComboBox. This sample checks whether an undo or redo operation can occur and then performs the appropriate action. The sample uses the CanUndo and CanRedo properties, and the UndoAction and RedoAction methods.

To use this example, copy this sample code to the Script Editor of a form. To run the code you need to open the form so the Open event will activate. Make sure that the form contains:

• A TextBox named TextBox1.

• A ComboBox named ComboBox1.

• Two CommandButton controls named CommandButton1 and CommandButton2.

Dim UserForm1 
 
Sub CommandButton1_Click() 
 If UserForm1.CanUndo = True Then 
 UserForm1.UndoAction 
 MsgBox "Undid IT" 
 Else 
 MsgBox "No undo performed." 
 End If 
End Sub 
 
Sub CommandButton2_Click() 
 If UserForm1.CanRedo = True Then 
 UserForm1.RedoAction 
 MsgBox "Redid IT" 
 Else 
 MsgBox "No redo performed." 
 End If 
End Sub 
 
Sub Item_Open() 
 Set UserForm1 = Item.GetInspector.ModifiedFormPages("P.2") 
 Set TextBox1 = UserForm1.Controls("TextBox1") 
 Set ComboBox1 = UserForm1.Controls("ComboBox1") 
 Set CommandButton1 = UserForm1.Controls("CommandButton1") 
 Set CommandButton2 = UserForm1.Controls("CommandButton2") 
 
 TextBox1.Text = "Type your text here." 
 
 ComboBox1.ColumnCount = 3 
 ComboBox1.AddItem "Choice 1, column 1" 
 ComboBox1.List(0, 1) = "Choice 1, column 2" 
 ComboBox1.List(0, 2) = "Choice 1, column 3" 
 
 CommandButton1.Caption = "Undo" 
 CommandButton2.Caption = "Redo" 
End Sub
