The following two methods are used to check whether or not there are any actions in stack:

  grid.CanUndo()
  grid.CanRedo()

And for monitor the actions performing, undoing and redoing, the following three events can be used to do that:

AddHandler grid.ActionPerformed, Sub(s, args)
                         MsgBox("Action Performed")
                       End Sub

AddHandler grid.Undid, Sub(s, args)
                         MsgBox("Undid")
                       End Sub

AddHandler grid.Redid, Sub(s, args)
                         MsgBox("Redid")
                       End Sub

Jing,
Can that tell me if there is any items left in the stack? so, i can disable or enable the buttons?

I've just updated my answer for check actions:)

You asked a nice question, I think there should be a document to describe how to use actions in ReoGrid.

Yes, it's same usage. I use them in ReoGridEditor.

Jing,
Would this work

ddHandler rgMainControlContainer.Undid, Sub(s, args)
                                                     If rgMainControlContainer.CanUndo = True Then
                                                         tbbUndo.Enabled = True
                                                     Else
                                                         tbbUndo.Enabled = False
                                                     End If
                                                 End Sub

or would this be better

 AddHandler rgMainControlContainer.Undid, Sub(s, args)
                                                     tbbUndo.Enabled = rgMainControlContainer.CanUndo()
                                                 End Sub

this the code for the Function for the undo and redo
As you can see i am checking to see if the grid is active control and doing undo and redo base on that..but i didnt have way to update the buttons, It work fine with short cut keys.

Private Function Undo() As Boolean
        Undo = False

        If rgMainControlContainer.Name = Me.ActiveControl.Name Then
            rgMainControlContainer.Undo()
            Undo = True
        Else
            frmUndoRedoManager.Undo()
            Undo = True
        End If
    End Function

    Private Function Redo() As Boolean
        Redo = False

        If rgMainControlContainer.Name = Me.ActiveControl.Name Then
            rgMainControlContainer.Redo()
            Redo = True
        Else
            frmUndoRedoManager.Redo()
            Redo = True
        End If
    End Function

Maybe you could use this:

AddHandler grid.LostFocus, Sub(s, args) Button1.Enabled = False
AddHandler grid.GotFocus, Sub(s, args) Button1.Enabled = True
