Undo with two richtextboxs VB.NET .net6

I am writing a program where it has two RichTextBox's on the same form. I am trying to make it so the Undo/Redo/Copy/Paste/Cut select all etc.functions run independently of each of the RichTextbox's. Instead of having to run two separate ContextMenus, MenuStrips and toolstrips.
I have duckduckgo for a solution but I'm hitting a wall.

What I have tried:

I have tried If statements, Try Catch Statements, With, Functions, While when. Also trying a different combinations in the the If statements of :

If RichTextBox1.Focus = True And RichTextBox2.Focus = False Then
    If RichTextBox1.CanUndo = True Then
        If RichTextBox1.UndoActionName <> "Undo" Then
            RichTextBox1.Undo()
        End If

    ElseIf RichTextBox2.Focus = True And RichTextBox1.Focus = False Then

        If RichTextBox2.CanUndo = True Then
            If RichTextBox2.UndoActionName <> "Undo" Then
                RichTextBox2.Undo()
            End If
        End If
    End If
End If

or

If RichTextBox1.CanUndo = True And RichTextBox1.TabIndex = 4 Then
    If RichTextBox1.UndoActionName <> "Undo" Then
        RichTextBox1.Undo()
    End If
Else
    If RichTextBox2.CanUndo = True And RichTextBox2.TabIndex = 8 Then
        If RichTextBox2.UndoActionName <> "Undo" Then
            RichTextBox2.Undo()
        End If
    End If
End If

I have also tried running the statements out of the Else. No matter what combination I try either it affects One RichTextbox1 and Not RichTextbox2 or it affects both of them at the same time.

Solution 1

VB

If RichTextBox1.Focused = true Then

   RichTextBox1.Undo()

End If

If RichTextBox2.Focused = true Then

   RichTextBox2.Undo()

End If

it's a basic,
first you check the focus 'on' of the first RTBox, then for the second RTBox.
'Better' is an enemy for the 'good' : 'elseif' are not simple to master.

Assuming Windows Forms, you need to check the Focused property; Focus is a method which will set the focus to the specified control, so both of your tests will pass.
