RadPageView: Adding Page while hamburger is closed causes hamburger to expand

I attached a video and the code I used. I am trying to remove and add pageviews. (I would hide them it i knew how)

When I add the pageview back in while the hamburger menu is closed it somewhat expands the tabs. I would like it to leave it closed

Hello, Don,

Following the provided information, I have prepared a sample project to test the described behavior. Indeed, if I add a RadPageViewPage to the Pages collection while the hamburger is closed, it gets expanded. The attached gif file illustrates better the obtained behavior with the sample project.

I have logged it in our feedback portal by making this thread public. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to disable the animation and force expand/collapse operations: 

    Sub New()

        Dim navigationElement = TryCast(Me.RadPageView1.ViewElement, RadPageViewNavigationViewElement)
        navigationElement.AllowAnimation = False
    End Sub
    Private Sub RadButton1_Click(sender As Object, e As EventArgs) Handles RadButton1.Click
        If Not Me.RadPageView1.Pages.Contains(Me.RadPageViewPage2) Then
            Me.RadPageView1.Pages.Insert(1, Me.RadPageViewPage2)
            Dim navigationElement = TryCast(Me.RadPageView1.ViewElement, RadPageViewNavigationViewElement) 
        End If
    End Sub

    Private Sub RadButton2_Click(sender As Object, e As EventArgs) Handles RadButton2.Click
        If Me.RadPageView1.Pages.Contains(Me.RadPageViewPage2) Then
        End If 
    End Sub 

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
