VB.NET Navigation Panel

Hi there,

I have been searching high and low for a solution to what seems like a standard layout for a navigation pane. I have managed to obtain outlook 'accordion' style navigation panes from around the net.

The one I am currently using is from http://www.codeproject.com/Articles/43181/A-Serious-Outlook-Style-Navigation-Pane-Control and it works really well. The problem I have is that I would like to have a pane or split container to the right of the pane of which will display the appropriate form that I code it to display on click. The same way outlook works when you click calendar or contacts etc.

Please, please can someon point me in the right direction. I have managed to change the panel to show the form but don't know how to dispose of the old form when another button is clicked?

    Private Sub VButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles VButton1.Click
        Dim frm As New Form1

        frm.TopLevel = False
        frm.Parent = Me.Panel1
        frm.Show()

        frm.Show()
    End Sub

    Private Sub VButton2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles VButton2.Click

        Me.Panel1.Controls.Remove(Form1)
        Dim frm2 As New frmBlank

        frm2.TopLevel = False
        Me.Panel1.Controls.Add(frm2)
        frm2.Show()

        frm2.Show()
    End Sub

Select allOpen in new window

I am sure there is a proper way of having a panel that changes according to the button that been clicked from my navigation form. Basically if you look at a tabbed website or even ms access 2010's navigation pane is what I am looking for? Your help is much appreciated
