Custom undo events?

beandog · Post by **beandog** » Fri Jan 27 2006

I am developing a wholly new user interface to the PDFCreactiveX control. So I have my own custom print, properties, page setup, etc. dialogs.

My question is, how do I make it so that users can undo the changes they make using my dialogs? Is there a way to insert a custom Undo level?

Hello Ben,

You can use the Undo command to undo the last actions. Here is a VB code on calling the Undo function you can definitely translate it to C#

Code: Select all

With PDFCreactiveX1
    If .UndoLevels > 0 Then
       .Undo
       .Refresh
    Else
        MsgBox "No more actions to Undo"
        Exit Sub
    End If
    
 End With

Hope this helps.
