Is components as Container needed for all custom controls?

Question

Hello, I'm learning designing of .net framework WinForms controls In a custom control I've seen:

Private components As System.ComponentModel.IContainer

and:

    Protected Overrides Sub Dispose(ByVal Disposing As Boolean)
        Try
            If Disposing AndAlso components IsNot Nothing Then
                components.Dispose()
            End If
        Finally
            MyBase.Dispose(Disposing)
        End Try
    End Sub

also in Private Sub InitializeComponent() :

Me.components = New System.ComponentModel.Container()

But this custom control has an ImageList component When designing my own custom control, which does not have any component (such as Image List) should I still insert the above code to my custom control? My custom control inherits the Panel with 1 Button and 1 TextBox inside, nothing more.

No, it is not needed. You can see MSDN samples for basic Custom Controls, like : How to: Develop a Simple Windows Forms Control
